Alastair Cook

When Cook retired from international cricket in 2018, he stated that he would continue to play for Essex, signing a three-year contract with them. In the 2019 County Championship season Cook helped Essex to win the title

After a score of 70 of the first match of the home series against Pakistan, Cook had another slump in form, scoring a total of 155 more runs in 5 further matches Pakistan and India. On 3 September 2018, after the conclusion of the fourth Test, Cook announced that his twelve-year international career would end at the conclusion of the series against India. On the fourth day of the fifth Test (after resuming on an overnight score of 46*), Cook made a score of 147 and in doing so became the fifth batsman to score a century in his first and last Test match and the second batsman to score twin fifties in his first and last Test. When he reached 76 during the innings, he overtook Kumar Sangakkara to become the fifth highest run scorer and the highest scoring left-hander in Test history.

Cook's form slump that had continued through the 2017-18 Ashes, where he had not scored a half-century in 10 innings, finally came to an end with 104* from 166 balls by the end of day two of the Boxing Day Ashes Test in Melbourne. He went on to carry his bat with a double century and put England into a lead of over 100, finishing with 244 not out, the highest Test score by an opener who has carried the bat. In December 2018 this record was bettered by New Zealand's Tom Latham, in his score of 264* vs Sri Lanka.

In the first Test against Sri Lanka, Cook could only make 16 but England went on to win the match by an innings and 88 runs. In the second Test, left handed batsman created history on 30 May 2016 in the second Test against Sri Lanka to become the youngest batsman to score 10000 Test runs beating Sachin Tendulkar's 11-year-old record. The 31-year-old broke the record on the fourth day of the second Test match against Sri Lanka at Chester Le Street. He became the 12th international cricketer to reach the landmark and the first Englishman. He scored 47 in England's second innings to help England to a convincing nine wicket victory. In the first innings of the third Test, he scored 85 to help England to 416. He came in down the order for England's second innings after being injured in the field and made an unbeaten 49. Rain on the final day meant the match finished in a draw, with England winning the series 2–0.

Cook broke India great Sunil Gavaskar’s record of 9,607 for the most runs as a Test opener while making 81 against Pakistan in the first Test at Lord's. However, Cook could only make eight in the second innings and England lost the opening Test by 75 runs. On 22 July 2016, Alastair Cook equalled Don Bradman's record of having hit 29 Test centuries when he scored 105 on the opening day of the 2nd Test against Pakistan at Old Trafford. He chose not to enforce the follow-on when England were far ahead in the second Test – but was vindicated by an England victory, with Cook scoring an unbeaten 76 in England's second innings. In the third Test he made scores of 45 and 66 and England won by 141 runs to go 2–1 up in the series. However, England lost the final match, with Cook scoring 35 in the first innings before making seven in the second innings as England lost by 10 wickets and the series ended in a 2–2 tie.

For his performances in 2016, he was named as captain of the World Test XI by the ICC.

In the second Test at Adelaide, Cook scored another century, his 15th, which saw him match Bradman in scoring 15 centuries before his 26th birthday. Cook broke Wally Hammond's record of runs scored without being out and Nasser Hussain's record of most minutes at the crease without being out, before being caught behind off an inside edge for 148 after over 1,000 minutes of being at the crease.

Cook captained England in the 2015 Ashes series, and although England won the first game, Cook could only manage scores of 20 in the first innings and 12 in the second. England lost the second Test by 405 runs, but Cook was one of the few England batsman to show any resistance, scoring 96 in England's first innings. With the series level Cook made 34 in England's first innings of the third Test and England went on to win the game by eight wickets. England won the fourth Test by an innings and 78 runs, meaning Cook only needed to bat once, scoring 43 in England's first innings. With the Ashes won, Cook was praised for his captaincy and he gave an emotional interview following the victory. England lost the final match of the series, but Cook was again one of few England batsmen to show any resistance with the bat as he scored 85 in their second innings. Despite the loss, England won the series 3–2 and Cook celebrated his second Ashes win as captain.

Cook scored his third double-century and 28th Test ton (263) against Pakistan in first Test at Abu Dhabi in October 2015 in 836 minutes: the longest innings by an Englishman and 3rd longest of all time, facing 528 balls. In doing so he also became the all-time highest non-Asian run scorer in Asia, overtaking Jacques Kallis' 2,039 runs. Despite Cook's brilliant innings, England were unable to force a victory, running out of time after bad light stopped play. In the second Test Cook scored 65 in the first innings as England posted 242. With England chasing down a big target to win in the second innings, Cook could only manage 10 and Pakistan won the match by 127 runs. England need to win the third Test to have any chance of drawing the series and despite taking a first innings lead which Cook contributed 49 to, Pakistan batted well in the second innings and England were dismissed for 256 in their second innings, meaning the lost the series 2–0, despite Cook scoring 63.

For his performances in 2015, he was named as captain of the World Test XI by the ICC. He was also named in the Test XI by ESPNCricinfo and Cricbuzz.

On 19 December 2014, Cook was removed as one-day captain, and replaced by Eoin Morgan. This was primarily due to his poor form in ODI cricket.

Cook has written a column in The Daily Telegraph and Metro. He used his skill with the saxophone to contribute to Freefonix, a CBBC animated series with music-based adventures. Cook has donated his time to various charities including taking part in The Great City Race for Breakthrough Breast Cancer and modelled naked alongside fellow cricketers James Anderson and Stuart Broad to help raise awareness for testicular cancer on behalf of the Everyman Campaign. Additionally, he is also an active patron of the David Randall Foundation, a charity that carries the name of his childhood friend and opening partner at Maldon CC & Essex age group sides. Much of the proceeds from his 2014 Benefit Year went to this charity.

In December 2011, Cook married Alice Hunt, whom he had known since childhood. The couple's daughter Elsie was born on 3 April 2014. He was allowed to miss a tour game in Bangladesh to be present at the birth of the second child, Isabelle, on 13 October 2016.

Returning home, Cook was again selected for the first XI during Sri Lanka's tour. For his debut match at Lord's, Cook was shuffled down to third to make way for the returning Trescothick. However, he still walked to the crease alongside his teammate as Strauss fell at the stroke of lunch. Cook and Trescothick put on 127 in their partnership as Trescothick made a century while Cook later stumbled just before at 89; there was no second innings as England enforced the follow-on but were one wicket away from victory, with Cook being targeted among others for two significant dropped catches. Cook's first taste of victory came in the second Test, guiding the team past the target of 78 in the second innings with an unbeaten 34 alongside Andrew Flintoff furthering the reputation of his calm, meticulous style of play against the dangerous spin of Muttiah Muralitharan who took 4–29. Although not initially selected for the one-day series, Cook made his limited overs debut in the fourth match scoring 39 from 38 balls in a bright spot of an otherwise dour England performance hampered by injuries.

Although normally known for his slow but focussed repose with the bat, the first Test against New Zealand gave Cook a chance making three sharp catches in the first innings and mirroring his efforts with three even more spectacular catches in the second innings, the first two off Ryan Sidebottom who then went on to make a hat-trick with a final LBW, the match itself saw England collapse in the second innings for 110 with Cook being the only other player besides Ian Bell to make it into double figures. Incidentally, Cook's other catch in the second innings was also off Sidebottom to dismiss New Zealand captain Daniel Vettori, a feat the pair reproduced in the second innings of the second Test and again in the first innings of the third Test. His batting meanwhile began its long road of decline scoring no more than sixty in the two Tests and falling for only two runs in the final match, though in the second Test he did secure another English record being the youngest Englishman at just over 23 years, to score 2,000 Test runs – again eclipsing Gower; two days later he recorded his first Test six after 2047 runs, including 233 boundaries, after an accidental top edge and ruined his chances of beating Vijay Manjrekar's 2,308 record.

Omitted from the World Twenty20 competition, Cook returned to Essex for two moderate county matches but impressive Twenty20 games. Despite being the only Englishman to score a century, or even more than 50, in the first innings of England's warm up match against Warwickshire, in the first Ashes Test at Cardiff, Cook was the lowest scoring recognised batsman, scoring 10 and 6 – caught in the gully in the first innings, and trapped LBW by Mitchell Johnson in the second. Cook bounced back in the second Test at Lord's, batting through to the afternoon session, as he and his captain Andrew Strauss (who scored 161) set the record for the highest opening English partnership at Lord's with 196, Cook initially scored faster than Strauss but fell short of another Lord's century, trapped again by Johnson for 95. This partnership, along with Strauss' anchoring throughout the innings, led England to a total of 425 and enabled them to gain a 210-run first-innings lead, aided by three catches from Cook off James Anderson and Stuart Broad. Batting quickly in the second innings to force victory, Cook scored 32 from 54 balls before again falling LBW but providing enough for England to cement their first victory over Australia at Lord's since 1934 and second since 1896.

In the Test series against Sri Lanka Cook made 133 in the first Test of the series to help England take a 1–0 lead. His good form continues into the next match where he made scores of 96 and 106. In the final match of the series Cook made 55 in his only innings of the match, meaning he had scored two centuries and two half centuries in his four innings. Cook's first game as full-time captain against Sri Lanka at the Oval saw England victorious by 110 runs. England went on to win the series 3–2, with Cook top scoring for England in the series with 298 runs in five matches. This performance also led to an ODI player of the series award.

Cook was expected to be a key player when England met India, with the series winners taking over the world number one spot. Although Cook failed to make a significant score in the first game, England won the match to go 1–0 up. Cook only scored seven runs in the entire match in the next game, although England again won to go 2–0 up. In the third match of the series Cook hit a brilliant 294 to help England win the game by an innings and clinch the World's number one spot. In the final match of the series he made 34 as England won the series 4–0. In the second ODI Cook made an unbeaten 80 to help guide England to victory. After making scores of 23 and 12 in the next two matches, Cook finished off the series in good form, making 50 in the final game as England won by six wickets.

England then travelled to India for a limited overs series overseas. Cook scored 60 in the first match but England lost by 126 runs. He scored just 13 runs in the next three games, which included being dismissed for a duck. In the final match of the series he returned to form, making 60. However, England again lost and suffered a 5–0 series defeat.

In the first Test against Sri Lanka England's form showed no sign of improving and they lost the first match of the series, with Cook being dismissed for a duck in the first innings. With the pressure on England going into the final match of the two Test series, Cook returned to his best, making 94 in the first innings before hitting an unbeaten 49 to help England level the series at 1–1.

England struggled in the three match series against South Africa, eventually losing the series 2–0. Cook started the series well, making yet another century in the first innings of the first match between the two sides. However, he was dismissed for a duck in the second innings as South Africa took a 1–0 lead. The next match ended in a draw, with Cook making decent contributions, despite failing to pass fifty. The third match was over shadowed when Kevin Pietersen was dropped following an argument with senior England players. Cook scored just ten runs in the match as England lost to lose the series 2–0 and lose their spot at the top of the Test rankings. Cook had an unsuccessful ODI series, the only 50 he made coming in the final match of the series. England lost the match and series finished 2–2.

Cook continued his impressive form in the ODI series, scoring 75 in the first match, which helped England win the game. Cook was less impressive in the next two games as India took a lead in the series after winning both games. Cook made 74 in the fourth game but England still lost and India took an unassailable 3–1 series lead. England won the last game meaning the series had finished 3–2 to India, meaning the tour was seen as a success and the transition from Strauss to Cook was seen as a smooth one.

After the tour of India, Cook led England in New Zealand. In the second ODI, Cook hit 78 to guide England to victory and level the series 1–1. England clinched the series by winning the decider, in which Cook made 46 to secure the series for England. In the first Test match, Cook made a century to help England battle to a draw after a poor showing in the first innings. Cook was not at his best in the final two games of the two, although the nature of the wickets meant that the batsmen found it easy to score runs, and so the series ended 0–0. Despite the pitches, many had expected England to win the series and the draw was seen as a disappointment.

Cook led England in the 2013 Champions trophy, and they won their first game against Australia. It was also Cook's first game as captain against Australia. Cook made 59 against Sri Lanka, but England lost the game meaning they were not assured of their place in the next round. Cook top scored with 64 as England narrowly beat New Zealand to book their place in the semi final. After beating South Africa in the semi finals, England played India in the final in what turned out to be a rain affected match. Despite restricting India to 129 in 20 overs, England lost the match by 5 runs, leaving them as runners up. Cook was named as part of the 'Team of the Tournament' by Cricinfo.

In the first Test against New Zealand on home soil, Cook got made good starts in both innings but was unable to convert these scores past fifty. Despite this England won the Test match. In the second match, Cook returned to form, making 130 and leading England to a 2–0 series win. This meant that England remained undefeated in Test series under Cook, winning two and drawing one. Cook played in the ODI series, despite calls for him to be rested ahead of the Ashes. He made scores of 30, 34 and 0 in the three match series, with England losing 2–1.

The 2013 home Ashes series marked Cook's first Ashes series as captain. England went into the series as strong favourites, with Australia recently having parted company with their coach. England won the first Test, with Cook making 50 in England's second innings to help them set Australia a competitive target to win the game. They were bowled out for 296, meaning England won the match by 14 runs. Although Cook only managed 20 runs in the next match, England cruised to victory, winning by 347 runs. The third match ended in a draw, with Cook scoring 62 in the first innings, but being dismissed for a duck in the second. The fourth Test saw England win the series after winning the match and taking a 3–0 series lead. The final match ended in a draw, with Cook failing to pass fifty in either of his innings. Despite this, Cook was generally praised for the way he had led the side. In the ODI series, Cook and Flower decided to rest several of England's Test players to ensure they were fit for the series in Australia. Cook himself played no part in the series, being replaced in the side by Michael Carberry.

England and Cook suffered a complete whitewash when they travelled to Australia for the 2013–14 Ashes series. They were heavily defeated in the first Test, losing by 381 runs. Cook top-scored in England's second innings with 65 but it wasn't enough as England slumped to defeat. The second match saw a similar humiliation as England lost by 218 runs. England surrendered the urn after losing the third Test, giving Australia a 3–0 series lead. Cook made 72 in the first innings but was dismissed for a duck in the second as England lost their third straight match by over 100 runs. The fourth Test saw Cook make another 50, but it wasn't enough to prevent another heavy defeat. England lost the final match and the series 5–0, with questions being asked of Cook's captaincy. Cook captained England in the ODI series but was unable to make a big contribution as England went 2–0 down. Cook scored 35 in the third match as England finally won their first game of the tour. However, they went on to lose the series 4–1. Upon returning from Australia, Andy Flower resigned but Cook vowed to continue as captain and was later backed by the ECB to help to mould a new England team.

For his performances in 2013, he was named as captain of the World Test XI by the ICC.

Cook continued in his role as captain for the home series against Sri Lanka. In the first ODI of the series he made just 11 runs. He followed this up with an unbeaten 30 in the third match and guided England to a ten wicket victory. He was out for just one in the next match as Sri Lanka levelled the series at 2–2. In the deciding match Cook made 56, his first half century of the summer, although it was not enough to prevent England losing the series 3–2. Cook continued to struggle for form in the Test series against Sri Lanka, scoring 17 and 28 as England drew the game. Cook was also criticised for not declaring earlier and not giving his bowlers enough time to win the game. England lost the next match, with Cook again failing to pass fifty in either innings, with his high score in the match being 33 in the second innings.

Cook went into the Test series against India under pressure following the defeat to Sri Lanka. In the first Test he scored just five runs. However, as the match edged towards a draw, he collected his maiden Test wicket of Ishant Sharma when he was bowling medium pace. Cook's poor form continued in the second Test when he made scores of 10 and 22 as England lost the game to go 1–0 down in the series. On 27 July, in the third Test against India at the Rose Bowl, Cook scored 95 in the first innings which showed that he was getting back in form with confidence before getting out to Ravindra Jadeja. He then went on to score 70 not out in second innings before declaring as England won the match to level the series. Although he only made 17 in the next match, his captaincy was praised as England won the game by an innings to take a 2–1 series lead. Cook made 79 in the final match of the series, which England again won to seal the series 3–1. Following the win, Cook revealed he had considered his position as captain but was convinced by his wife to continue. After the first match of the ODI series was rained off, Cook made 19 in the second ODI as England suffered a defeat. They went 2–0 down in the series after losing the next game, although Cook batted well, making 44. He made just 9 in the next match as India clinched the series 3–0. Following the defeat questions were asked over Cook's role in the ODI team. However, the team bounced back to win the final game of the series in convincing fashion, with Cook making 46.

Cook captained England for the ODI tour of Sri Lanka. However, he did not perform well in the first two matches, making scores of 10 and 22 as England lost both games. England won the third match, with Cook making 34, although he was later banned for the next game due to a slow over rate. In the fifth match he scored 20, as England won to keep the series alive. However, they lost the last two games, with Cook making scores of 1 and 32. The 5–2 series defeat lead to questions over Cook's leadership of the team.

Cook continued his captaincy of the Test team, having not scored a century since May 2013. In the first Test of the three-Test series, Cook registered scores of only 11 and 13, in an otherwise strong performance from England. The match finished in a draw. Cook took advantage of favourable batting conditions in the following Test, making 76 in an opening partnership of 125 in England's first innings with Jonathan Trott. It was England's first century opening partnership since March 2013, and Cook's innings took him past Alec Stewart to become England's second-highest run-scorer in Tests. In the second innings, Cook made 59* in a comfortable run chase to win the Test by nine wickets and help England to secure 1–0 lead in the three match series. In the third Test in Barbados, Cook scored 105 in England's first innings, his first Test century in almost two years. However he made only 4 in the second innings, as England slumped to 123 all out. West Indies comfortably chased the runs they needed to gain a victory, making the final result for the series 1–1.

The English team then welcomed the Black Caps in May, with the first Test of the two-match series at Lord's. In the first Test, Cook continued his resurgence with his 27th century in Tests, scoring 162 in the second innings as England ultimately made 478 all out. England went on to win the game by 124 runs to go 1–0 up in the series. Cook continued his good form in the second Test. He made 75 in England's first innings as they posted 350 to equal New Zealand's first innings score. New Zealand were able to build up a big lead in their second innings, and although Cook made 56 in the final innings in the match, England lost the match by 199 runs and the series finished tied at 1–1. During the second Test, he became England's leading run scorer in Test matches, as well as the first England player to score 9,000 runs in Tests and the first to score 1,000 Test runs against five different nations.

In the Test series against South Africa, Cook made a duck in the first innings of the first Test, but England recovered to post 303. England went on to win the game by 241 runs thanks to a strong bowling performance. In the second Test Cook again failed to make a major impression, scoring just 35 runs in the entire match in what proved to be a high scoring draw. Cook started to show some form in the third Test. He scored 43 in England's second innings total of 74–3, as England won the game by seven wickets after dismissing South Africa for just 83 in their second innings. In the final Test of the series, which England had already won, Cook made 76 in the first innings. However, England collapsed in the second innings and only made 101, with Cook being dismissed for five. Despite this, England won the series 2–1 with Cook captaining England to the historic victory.

In the first Test against Bangladesh, Cook scored 4 in the first innings and then made 12 in the second. Despite his low scores, England won by 21 runs. In the second Test Cook made 14 in the first innings, and although he made 59 in the second, England were bowled out for 164 to lose the match by 108 runs and draw the series 1–1.

The first Test at Lord's was Cook's first under the new captain, Joe Root. Cook didn't score a century in the series but was reliable with three 50s. England won the 4 Test series 3–1 with the only loss at Trent Bridge. Cook's top scored in the second innings there with 42, with no other England batsmen offering much resistance.

Cook and James Anderson have taken part in an exhibition darts series against each other with Cook leading the series 2–0, winning both 1-Leg shootouts.

He was appointed captain of the Test team after fellow opener Andrew Strauss's retirement on 29 August 2012. Cook captained England to its first Test series victory in India since 1984–85. During the tour he became the first captain to score a century in each of his first five Tests in charge. On 30 May 2015, Cook became the leading run-scorer in Test matches for England, surpassing Graham Gooch (8900). After England's 2016 tour of Bangladesh and India, he stepped down as Test captain. Cook was appointed MBE in 2011 and promoted to CBE in 2016 for services to cricket. On 24 May 2018 during the first Test against Pakistan, Cook equalled Allan Border's record for appearing in the greatest number of consecutive Test matches, with 153, surpassing it a week later in the second Test at Headingley. On 3 September 2018, Cook announced that his twelve-year international career would end at the conclusion of the series against India on 11 September 2018. In the 2019 New Year Honours, Cook was appointed a Knight Bachelor for services to cricket.

In the winter of 2012, England struggled in Test matches in the sub continent. They were beaten by Pakistan in the first match of the series, with Cook being dismissed for single figures in both innings. He made 94 in the next game, the only time he passed 50 in the tour, but it was not enough to prevent England losing the match and going 2–0 down. Cook was out cheaply in the first innings as England were again bowled out for less than 200, and although he made 49 in the next innings it wasn't enough to prevent another England defeat.

On 29 August 2012, Cook became England's Test captain after previous Test captain Andrew Strauss retired from all forms of cricket.

Cook, who captained England in Bangladesh for two Tests in a previous series, took charge of England for the Test series against India in the winter of 2012. In each of the first three Tests – the first a defeat and the second a ten-wicket victory – he scored a century. This, together with a century in each of the aforementioned two Tests in Bangladesh, gave Cook five centuries in five Tests as captain, a record number. His scores on the tour also included 119 and 97 in the warm-up matches. The ten-wicket victory in the second Test was lauded by the media as one of England's greatest victories, and Cook's run of hundreds brought him level with the English Test record for most centuries. On 6 December 2012, Cook became England's leading scorer of centuries after making a hundred against India in Kolkata.

On 7 December 2012 he captained England to its first Test series victory on Indian soil since 1984–85, as well as overtaking Mike Gatting as England's highest ever run scorer in India For his performances in 2012, he was named both in the World Test XI and ODI XI by the ICC . He was also named in the World Test XI by the Cricinfo.

Following England's quarter-final departure from the 2011 World Cup, Andrew Strauss resigned the ODI captaincy and Cook was named his successor, despite not having featured in an ODI since leading the side in Bangladesh. In addition to Cook's promotion, seam bowler Stuart Broad was named captain of the Twenty20 side and England went into the home series with Sri Lanka with different captains for each format of the game.

For his performances in 2011, he was named in the World Test XI by the ICC and Cricinfo.

Although there were still concerns about Cook's form and technique ahead of the 2010-11 Ashes series, Cook answered his critics in the best way possible. Following a century in one of the warm-up games, Cook opened his series account with 67 as England won the toss and batted at the Gabba in Brisbane. After surrendering a first-innings deficit of 221, Cook fought back with fellow-opener Strauss and Jonathan Trott. Strauss scored 110 as England scored 188 for the first wicket. With this partnership, Cook and Strauss became England's highest scoring opening partners across their four years together, beating an eighty-year-old record set by Jack Hobbs and Herbert Sutcliffe; albeit taking 44 more innings to do so. Cook was joined by Trott and they scored an unbeaten partnership of 329; Cook recorded his first double-century in first-class cricket, finishing on 235 not out, and Trott scored 135 not out before England declared on 517–1. Cook's 235* overtook Don Bradman's record score at the ground and several other records were set in that innings.

The 2009 English season featured an early Test series against the West Indies where, despite being in the Test team, Cook joined Essex in a tour match. He scored 76 not out in the second innings before the match was rained off, stopping Essex pressing for victory. Before the Test series he helped Essex force the follow on against Kent in the County Championship but faltered with his team, scoring only 4 in the second innings to lose by 192 runs. After the Test series, Cook was omitted from the one day side leaving him free to play for Essex. He joined them in their bid to defend their Friends Provident Trophy matching Varun Chopra's 65 in a 124 run partnership against Lancashire to gain a place in the semi-final. He and his team could not recreate the same form for the semi-final, at the same location against the same team three days later, after being caught from a running catch by Sajid Mahmood, seeing the team lose by 67 runs. Having been knocked out of the FP Trophy, the team turned to the Twenty20 Cup. Making only his fourth appearance in the tournament since 2005, Cook hit 80 off 56 balls in a match against Kent that was rained off. While his England partner Bopara scored 45 against Sussex, Cook only scored one but made up for this with a 60 run partnership with Bopara days later to put Essex top of the table. Despite averaging 49 from these four games, Cook felt he was a long way from the international squad. In his last performance before joining the Ashes squad, Cook scored a 57 ball century, and batted throughout the whole innings as they beat Surrey, but without Cook and Bopara, the team were knocked out after two successive losses.

After being omitted from the World Twenty20 Cook rejoined England in Sri Lanka making an outstanding contribution in both forms of the game. Starting with another ODI series victory, Cook battled with a stomach virus to top score 47 in a losing match and went on to be the second highest scoring batsmen in the series behind Chamara Silva with 155. Cook also picked up his first ODI Man of The Match award in the fourth game after scoring 80 to help England win by five wickets. After an unsuccessful first Test, Cook went on to be the top scoring Test batsmen for England too, scoring two half centuries in the second Test and 118 in the third match, at an average of 46. Up until this tour, Cook had held a strange record of having more Test centuries than half centuries but this century marked his last until March 2009 and Cook came under increasing criticism for his lack of ability to convert fifties to hundreds at the top of the order, yet maintained an average in the low forties.

With a year to go before the 2009 Ashes, it was imperative for Cook to cement his position as opener in the home series against South Africa. Again, at Lord's, Cook made his way comfortably to a half-century before being dismissed for 60. A high team score, together with a benevolent wicket, saw the fifth day bring Cook's first Test over as a bowler: he conceded just one run. Cook fell in one innings of each Test between fifty and a hundred, amassing the considerable average of 47 for the series.

Cook made his return to international Twenty20 cricket during the tour of South Africa in 2009–10. After scoring 11 runs in the first match, Cook was handed the captaincy after Paul Collingwood picked up an injury prior to the second match but led them to an 84 run loss after posting only 26. In the second Test he scored a patient 118 after being saved by a third umpire referral at 64. This, along with a century from Ian Bell, gave England their only Test win of the drawn series with an innings margin. Despite a meagre performance in the rest of the series, it was quickly announced that England's 2010 tour against Bangladesh would see Strauss rested, with Cook taking on the captaincy role in the Test and One-Day teams as, what national selector Geoff Miller, "an audition for future engagements".

In his first Test as captain in Chittagong, Cook led the team to a win, despite a strong rearguard from Bangladesh, with the top score in both innings. Scoring a century in the first, in the second innings he accumulated 4,000 Test which coincided with teammate Collingwood achieving the same. At 25 years, 79 days Cook became the youngest Englishman to reach this amount and the second youngest worldwide after Indian veteran Sachin Tendulkar who was 24 years, 224 days old. In the second Test, Cook scored the winning runs in a nine wicket win, having scored another century. By virtue of being captain, Cook returned to England's ODI squad for the first time since 2008 and led the team as an opening batsmen to a three win whitewash with respectable scores.

After his England call up, Cook's appearances at Essex significantly reduced. In the County Championship he appeared in only three matches, making two hundreds and another two fifties in his five innings, topping the season averages with an inflated 141.3. Similarly in the Cheltenham & Gloucester Trophy he appeared only three times and again topped the batting averages, only being out once with a top score of 91 and average of 148. He scored less favourably in his one Twenty20 Cup appearance, scoring only nine runs. In the 2007 season, for Essex alone his first-class average was only 58.8 from three appearances, making two hundreds but countering this with one duck and he made a similar century/duck appearance in the (formerly C&G) Friends Provident Trophy during his 5 matches averaging 38.4. The back to back Totesport/Pro40 champions saw Cook make only one appearance in that competition, scoring 81 not out, before being relegated. They won Division Two and were promoted the following season, though Cook only provided 11 runs in one innings during the tournament. Despite his international commitments Cook managed to participate in at least one match of each tournament averaging 36.16 in three County Championship matches and 15 in his one Twenty20 match. Given time off the South Africa One-Day series, Cook fared better in the FP Trophy with 45.3 from 3 matches including contributing the second highest in the final at Lord's to seal the trophy.

After being omitted for the Twenty20 International against Australia and the 2007 World Cup, Cook found himself once again in favour for the home series against West Indies. Starting at Lord's, Cook found himself among four centurions in the opening innings with Collingwood opposite him once again, being one of only five Englishmen to hit as many centuries in 15 Tests and recorded another half century in the following innings to win his first Man of The Match award. After another half century in the second Test, Cook recorded another half century/century combination in the two innings at Old Trafford, his first innings sixty equating to the team's win margin. Cook was selected for his first Twenty20 International against the West Indies, in a losing effort where he scored 15 runs from 16 balls. This was followed by a disappointing one-day series for Cook, and England, who averaged 22 in 3 matches.

As well as the one day series against Pakistan, Cook was overlooked for the 2006 Champions Trophy squad. However, he was named for the 2006–07 Ashes series touring party and when Trescothick pulled out once again due to stress, Cook re-earned a spot as an opener for the foreseeable future. In the disastrous 5 Test whitewash, Cook failed to impress in the first two Tests, but during a two-day warm-up he retired with a century and afterwards remained adamant that he and England would make a turn around in the series. With England desperately chasing 577 runs, or a draw to not lose the Ashes, Cook stayed at the crease for over six hours, lasting almost all of the fourth day to earn his maiden Ashes century (119) before being caught behind off Glenn McGrath just shy of three overs before the close of play. This was his fourth Test century before turning 22, no England player had scored more than two by the same age. With only three other batsmen scoring double figures, England lost the Test and the Ashes and despite only having an average of 27.6 runs, Cook scored one of only three English centuries on the tour and also on 28 December 2006 in Melbourne, Cook scored his thousandth Test run, the second cricketer to do this in their maiden year, after Mark Taylor.

For his performances in 2006, he was named in the World Test XI by Cricinfo.

His exploits in his single season gained enough attention for him to be brought in as opening batsman for the MCC in 2005 season's opener against County Champions Warwickshire. With a century in the first innings and 97 in the second, Cook helped secure victory in a match destined for a draw. The season opener would not be Cook's only highlight for the year: as the Ashes approached, Australia were touring the counties and in a two-day match (which did not count towards his first-class statistics) Cook scored a double century and went on to take the first wicket of Justin Langer with a catch in the drawn match days after being awarded PCA Young Cricketer of the Year. A further highlight of the season saw Cook help Essex to achieve one of Durham's two defeats of the season, scoring 107 of Essex's 245 before taking his maiden first-class wicket, followed by another two, with his off-spin. Cook played in every first-class match for Essex and also helped them clinch the Totesport League Title for the first time in 20 years. The end of the season saw Cook finish with an average of 48.03 in the County Championship, hitting four centuries.

After the 2005 domestic season he was part of the intake for the ECB National Academy, but this was interrupted as he flew to Pakistan to cover the squad for Michael Vaughan's knee injury. After not being used in the first XI he travelled back with the Academy to the West Indies in the new year scoring 101 in a two-day match against Antigua before youth cricket came to an abrupt halt for Cook.

Cook was included in the ECB National Academy in the winter of 2005–06. The Academy's tour of the West Indies was cut short on 24 February for Cook who only appeared in the first innings, scoring only 6, before being called up, alongside James Anderson and Owais Shah, to the England tour of India to replace captain Michael Vaughan, who was suffering from a knee injury, and opener Marcus Trescothick, who was suffering from stress. Unlike Shah and Anderson, Cook was welcomed straight into the England XI and made his Test debut aged 21, days after he had flown in from the West Indies. He made an instant impact, opening with Andrew Strauss and scoring a half century in the first innings before being bowled just before tea on the first day for 60 runs from 160 balls being the second top scorer after 134 from Paul Collingwood. The second innings would prove to cement him in cricket history as he went on to score 104 not out before England declared, making him the sixteenth Englishman to score a century on his debut Test and an even more exclusive list of five to score 100 and 50 in their first Test. His hundred was also the 3,000th century in Test cricket. Despite being known for a patient style of play, an impending declaration forced Cook to play quickly to bring up the century; regardless, the match was drawn. After a mediocre outing in the losing second Test, scoring 17 and 2, he missed the Third Test due to a stomach illness and was omitted from the one-day series.

The following home series against India saw Cook continue his fine Test form despite England not winning a Test. He was the third highest scoring Englishman with an average of 37. In the first Test, Cook made scores of 36 and 17 as the match ended in a draw. During the first day of the second Test at Trent Bridge, Cook became the youngest English player to rack up 1,500 Test runs eclipsing the record held by David Gower. In the first innings of the third Test, Cook made his biggest score of the series, 61 and followed this up with 43 in the second innings to help England secure a draw. Cook played in six of the seven ensuing one-day matches, scoring his maiden ODI century in the first match alongside Ian Bell's 126 not out guiding England to a 104 win victory that propped up England's first one-day series victory since 2005. After two ducks, Cook was dropped in the final, decisive match.

Cook played for Essex's Academy and made his debut for the first XI in 2003. He played in several of England's youth teams from 2000 until his call up to the Test side in 2006. While touring in the West Indies with the ECB National Academy, Cook was called up to the England national team in India as a last-minute replacement for Marcus Trescothick and debuted, aged 21, with a century. He went on to score 1,000 runs in his maiden year and made centuries in his first Test matches against India, Pakistan, the West Indies and Bangladesh. Cook played a pivotal role in England winning the 2009 Ashes series, and, after deputising as Test captain in 2010 and then taking ODI captaincy full-time, in retaining the Ashes in 2010-11.

Over the next four years, he hit 17 centuries and two double-hundreds to total 4,396 runs at an average of 87.90, captaining the cricket team in his final year under coach Jeremy 'Boris' Farrell, as well as being President of the Music Society. He also gained three A-Levels and nine GCSEs. In his final year at Bedford in 2003, he scored 1,287 runs for the school, including two unbeaten double-hundreds, averaging 160.87 to take the school record. After his international success, Cook returned for an Old Boys' match at Bedford in 2008, playing for the Head Master's Ultimate XI. Later on, Cook spent two years at Alleyn's School as a PE master.

Having been a member of the Essex Academy since the age of 16, Cook was given his first-class debut for Essex against Nottinghamshire County Cricket Club on leaving school at the end of the 2003 season; put in to field he aided the first dismissal with a catch before scoring just 13 runs in his first innings but pushing Essex to a nine wicket victory with 69 not out in the second. Despite Essex's relegation being assured, Cook still battled away with an opening stand of 122 opposite Will Jefferson in the second innings of his second match, against Warwickshire. In the six innings in which he participated he quickly racked up three half centuries at an average of 47.80. Having secured his place as opener in the county team, he made his maiden first-class century against Leicestershire in May 2004 with 126 opposite Jefferson's 128 for a 265 opening stand, Essex's third highest but the team failed to secure promotion.

Cook had his first taste of international cricket playing the U15 World Cup in 2000. Three years later Cook was called up to the England Under-19 team for their tour of South Africa. After it was decided Samit Patel had enough responsibility batting and bowling, Cook was appointed captain of the team the following year, 2004. His first call of duty was the U19 World Cup in the West Indies where he guided England through the group stages and on past the Super League stage, including an unbeaten century-each partnership with Patel against New Zealand, and continued a 100% win record with 87 over eventual winners Pakistan before falling short in the semi-final against the West Indies. He went on from there to captain them in a U19 Test win over Bangladesh before taking the One-Day series too. His career with the Under 19 team was cut short when Kevin Pietersen was called up to replace Andrew Flintoff in the main team, leaving a spot in England A tour of Sri Lanka for Cook.
