Stan Wawrinka

At the 2020 Australian Open, Wawrinka beat Damir Džumhur in four sets in the first round before defeating Andreas Seppi in five sets in the second round. He then progressed to the fourth round after John Isner retired with injury and upset Daniil Medvedev in five sets to reach the quarterfinals. Wawrinka then lost his quarterfinal match to Alexander Zverev in four sets.

Wawrinka started his 2019 season at the Qatar Open, where he lost in quarterfinals to eventual champion Roberto Bautista Agut. At the Australian Open, for a second straight grand slam tournament, he was defeated by Raonic in four sets, this time in the second round. At the Rotterdam Open, Wawrinka reached his first tournament final in over 20 months, where he fell to Gaël Monfils in three sets, and this was followed by a three set defeat to Nick Kyrgios in the quarterfinals of the Mexico Open.

He made his return to the tour at the 2018 Australian Open, where he lost in the second round to Tennys Sandgren in straight sets. His next tournament was the Sofia Open, where he lost in the semifinals to Mirza Bašić. Then he entered the ABN AMRO World tournament, where he lost in the first round to wildcard Tallon Griekspoor. His next tournament was the Open 13 in Marseille, France. He retired during his first match, trailing Ilya Ivashka by one set, at 1–1 during the second set because of his knee injury.

After missing almost three months due to his injury, Wawrinka returned in the 2018 Italian Open but lost in the first round to Steve Johnson in straight sets. He then played at the 2018 Geneva Open where he was the two-time defending champion but his title defense ended in a straight sets defeat to Márton Fucsovics in the quarterfinals. In the 2018 French Open, he was seeded 23rd, but lost in the first round to Guillermo Garcia-Lopez in five sets, which made him drop from 30 to 263 in the rankings. He entered Queens as a wildcard, losing to fifth seed Sam Querrey in the second round. He gained entry to Eastbourne as a wildcard, where, in the first round, he played Andy Murray, who was playing just his second tournament after a year-long absence from the sport. Wawrinka lost in straight sets.

Entering Washington as a wildcard, he narrowly lost to Donald Young in the first round. He also received wildcard entry to the 2018 Rogers Cup, where he defeated 16th seed Nick Kyrgios in the first round and Márton Fucsovics in the second before being defeated by top seed and eventual champion Rafael Nadal in two close sets. At Cincinnati, he defeated Diego Schwartzman, Kei Nishikori, and Márton Fucsovics before falling to Roger Federer in three sets in the quarterfinals.

Wawrinka entered the 2018 US Open as a wildcard, where he was again drawn against Grigor Dimitrov in the first round. He triumphed in straight sets and advanced to the third round, defeating Ugo Humbert in four sets. He then lost to Milos Raonic in the third round.

Warwinka received a Wild Card and entered the St Petersburg Open beating Karen Khachanov, Aljaž Bedene and Damir Džumhur before losing to Martin Kližan. He received a wildcard for the 2018 Shanghai Rolex Masters.

To start his 2017 campaign, Wawrinka chose not to defend his Chennai Open title (he had won the previous 3 editions), and played in Brisbane instead. He reached the semifinals, losing to No. 5 Kei Nishikori in straight sets. At the Australian Open he barely escaped a first round exit by beating Slovakian player Martin Kližan after being down a break in the 5th set. He then played Steve Johnson and beat him in straight sets and played Viktor Troicki in the third round, winning in four sets. In the fourth round, he played Italian Andreas Seppi, beating him in three tight tiebreaks to progress to the quarterfinals. He then beat 12th seed Jo-Wilfried Tsonga in three sets, to set up a semifinal against his compatriot and 17th seed Roger Federer. Wawrinka lost the all-Swiss clash, recovering from a two sets to love deficit and holding numerous breaking points in the opening games of 5th set only to ultimately lose 3–6. Federer went on to win the tournament. Despite the loss this result elevated Wawrinka back to No. 3. Wawrinka was then upset by Damir Džumhur in the first round of the Dubai Duty Free Tennis Championships in straight sets.

Wawrinka then entered Wimbledon with the chance to complete his career Grand Slam, but lost his opening match against Daniil Medvedev, a Russian player who was making his Wimbledon debut, in four sets. There was speculation that Wawrinka had an injured knee, and Wawrinka confirmed it by announcing that he would be taking time off to heal. On 4 August 2017, Wawrinka announced that he would undergo surgery to repair the damage on his knee, and that he would miss the remainder of the 2017 tennis season.

He then played in the Australian Open where he was the 4th seed. He started against Dmitry Tursunov who was here on a protected ranking. Wawrinka won the first two sets before Tursunov had to retire due to injury. He then played qualifier Radek Štěpánek. He won in straight sets. He then proceeded to the third round where he played Lukáš Rosol. He also won in straight sets. Then in the fourth round he played big serving Canadian and 13th seed Milos Raonic. Despite pushing it to a fifth set he was unable to overcome the Canadian and lost. It also snapped Wawrinka's streak of 6 consecutive quarterfinals or better appearances in Grand Slams.

At the Miami Open Wawrinka lost in the first round to Andrey Kuznetsov. Next up was the Monte-Carlo Masters with wins against Philipp Kohlschreiber and Gilles Simon. He then suffered a two set loss to the eventual champion, Rafael Nadal. Wawrinka then suffered another first round exit at the Madrid Open to Nick Kyrgios. He then competed at the Rome Masters as the 4th seed. He had a three set win against Benoît Paire but then had a three set loss to Juan Mónaco, who was here with a protected ranking. At the Geneva Open Wawrinka had two easy wins against Albert Ramos-Viñolas and Pablo Carreño Busta, and a three set victory over Lukáš Rosol. In the final he played Marin Čilić. He won his 3rd title of the year with a tight straight sets win.

His next tournament was the second major of the year, the French Open, as the 3rd seed and the defending champion. Against Lukáš Rosol Wawrinka was down two sets to one, but came through in five sets. Wins over Taro Daniel, Jérémy Chardy and Viktor Troicki sent Wawrinka to the quarterfinals, where he dispatched Albert Ramos-Viñolas in straight sets. In the semifinals he played 2nd seed Andy Murray. He lost in four sets. He then played at Queens in the Aegon Championships as the second seed. However he suffered a straight sets defeat to No. 53 Fernando Verdasco in the first round. His next tournament was at the Wimbledon Championships, as the 4th seed. In the first round he faced Taylor Fritz and won in four sets. However, he was beaten in the second round by Juan Martín del Potro on the comeback in four sets. After missing the Olympics due to a back injury, Wawrinka played at the Cincinnati Masters. However, he would lose to Grigor Dimitrov in two sets in the third round.

Prior to the start of the U.S. Open, Wawrinka returned to the Top 3 in the ATP Rankings due to Roger Federer being unable to defend his title in Cincinnati due to injury. In the first round he faced Fernando Verdasco, beating the Spaniard in straight sets. He then faced qualifier Alessandro Giannessi, also winning in three sets. He then played a four-hour match in the third round against British player Daniel Evans, which saw Wawrinka save a match point in the fourth set tiebreak, before beating Evans in five sets. He then defeated Illya Marchenko in four sets in the fourth round. In his fourth consecutive quarterfinal appearance at the U.S. Open, he defeated Juan Martín del Potro in four sets. He defeated Kei Nishikori in the semifinals in four sets and went on to defeat Novak Djokovic in four sets to win the 2016 U.S. Open, his third major title in as many years and his eleventh consecutive win in a championship final. With this victory, Wawrinka improved his record to 2–0 in major finals against Djokovic and 3–0 in overall major finals, and he remained the only player to defeat Djokovic in Djokovic's twelve Grand Slam finals dating back to the 2014 Wimbledon championships. Much as Wawrinka's 2015 French Open victory denied Djokovic the 2015 calendar year Grand Slam, his win at this tournament denied Djokovic claiming three Grand Slam victories in successive years (2015 and 2016). It should also be noted that Wawrinka defeated the No. 1 player in the finals of all three of his grand slam titles. The 2016 US Open final was even more impressive as it was the only time in 2016 that Djokovic won the first set but lost the match (53–1).

At the US Open, Wawrinka upset defending champion Novak Djokovic in the round of 16; Djokovic pulled out after dropping the first two sets. It was their first match since Wawrinka's victory in the 2016 US Open final. He went on to lose the quarterfinal to Daniil Medvedev.

As of June 2016, Wawrinka wears Yonex clothing and shoes and uses the Yonex Vcore 95D racquet with the Yonex Vcore Dual G paint job, formerly playing with a Yonex VCORE Tour 97 paint job. Wawrinka has been known to use Babolat's RPM Blast as his string of choice, opting to string his rackets at 27 kilograms in the main strings and 25 kilograms in the cross strings. Previously, he used Head tennis racquets, first the Flexpoint Prestige MidPlus and Microgel Prestige pro, and then the YOUTEK Prestige Pro MidPlus. Wawrinka is also an ambassador for the TGV Lyria train service between France and Switzerland, with his photo appearing on the exterior of the high-speed trains.

Wawrinka continued his dominant Grand Slam form at the US Open, with wins over Albert Ramos, Chung Hyeon, Ruben Bemelmans, Donald Young. He then beat South African Kevin Anderson in straight sets in the quarterfinals to advance to the semifinals, where he was dispatched in straight sets by Roger Federer. Wawrinka then helped Switzerland advance to the Davis Cup World Group with a five-set win over Dutchman Thiemo de Bakker in Geneva. He then competed in the Rakuten Japan Open Tennis Championships, entering as the first seed. Wawrinka avenged his loss to Tatsuma Ito at the same tournament the previous year by defeating him in the second round. He eventually advanced to the finals, where he beat Benoît Paire in straight sets and won his fourth title of the season. Wawrinka then entered the Shanghai Rolex Masters, where he defeated former US Open champion Marin Čilić in a three-set battle before losing in straight sets to Rafael Nadal in the quarterfinals. Playing in the Paris Masters, Wawrinka avenged his previous loss to Rafael Nadal in Shanghai with a two set victory. In the semifinals, Wawrinka lost to Novak Djokovic in a three set match. He then matched his performance at the ATP World Tour Finals the previous year by reaching the semifinals in London with round-robin wins over Andy Murray and David Ferrer. In the semifinals, Wawrinka played Roger Federer for the fifth time in the 2015 season, losing in straight sets.

Wawrinka began dating WTA player Donna Vekić in 2015, their relationship becoming public knowledge after Nick Kyrgios abused Wawrinka over it during a match at Montreal. Kyrgios was subsequently fined and given a suspended ban for his comments. Wawrinka and Vekić were reported to have split in May 2019.

Wawrinka appeared in the 2015 ESPN body issue, posing nude in athletic poses.

He has reached four Grand Slam singles finals in his career to date, winning three: the 2014 Australian Open, the 2015 French Open and the 2016 US Open; each time he defeated the reigning world No. 1 in the championship match (Rafael Nadal once and Novak Djokovic twice, respectively). In doubles and team tennis for Switzerland, he has won a gold medal in the men's doubles event at the 2008 Summer Olympics, partnering with Roger Federer, and the Davis Cup in 2014. He played in the longest doubles match in history at the 2013 Davis Cup, in a tie against the Czech Republic, partnering with Marco Chiudinelli.

Possessing one of the strongest one-handed backhands on tour, Wawrinka is characterized as a powerful offensive baseliner capable of playing well on most surfaces, especially on clay and hard courts. He is known for his fast serve which has reached as high as 232 kilometres per hour (144 mph). His forehand, considered a weakness early in his career, has improved significantly and is now a big weapon in his game. While he is primarily known as a baseliner, Wawrinka has occasionally backed up his game with approaches to the net, and is capable of using the serve and volley tactic. Wawrinka is known by the nicknames "Stanimal" and "Stan the Man" for both his play style and ability to win in big matches, particularly between the 2014 Australian Open and the 2016 US Open.

On 11 July, at Gstaad, Wawrinka progressed into his first ever career final, in doubles, with Marc Rosset as his partner. The Swiss pair lost in the final to Leander Paes and David Rikl. That year Wawrinka had his Davis Cup debut with the Swiss National Team. Wawrinka lost his first match against Victor Hănescu in a dead rubber. Switzerland won the tie 3–2 against Romania and progressed into the World Group quarterfinals. He finished the year ranked No. 162 in the world rankings.

Wawrinka became the 13th seed at the Monte-Carlo Masters and defeated Victor Hănescu in the first round in a rematch of the Casablanca final. He then beat Latvian Ernests Gulbis to advance to the third round. He was defeated by Novak Djokovic. Wawrinka reached the quarterfinals in Rome, losing to Rafael Nadal, and the semifinals in Belgrade, losing to John Isner. At the French Open, where he was the 20th seed, he reached the fourth round without dropping a set, defeating Jan Hájek in the first round. In the second round, he defeated German Andreas Beck, and in the third round, he beat Italian Fabio Fognini, before losing to Roger Federer in the fourth round.

Wawrinka made the fourth round of the French Open after defeating Flavio Cipolla, Andújar, and Gilles Simon. He was defeated by Jo-Wilfried Tsonga in the fourth round, once again coming from two sets down to take the match into a fifth set and recovering a 4–1 deficit in the decider before Tsonga finally prevailed.

In the first round of the Davis Cup on 2 February 2013, he played the longest ATP doubles match in history. He and Marco Chiudinelli were defeated by Lukáš Rosol and Tomáš Berdych of the Czech Republic in 7 hours and 2 minutes, including a 46-game-long final set. The match was the second-longest ATP match ever (singles and doubles combined).

At the Australian Open, Wawrinka beat Andrey Golubev and Alejandro Falla in the first two rounds, then had a walkover when Vasek Pospisil pulled out of their third-round match, followed by a straight-set win over Tommy Robredo. Wawrinka's quarterfinal opponent was Novak Djokovic, and this time Wawrinka won in five sets, taking the deciding fifth set 9–7 after being a break down. The victory ended a 14-match losing streak against the three-time reigning champion. He then faced off against another first-time Australian Open semifinalist, Tomáš Berdych, winning the match in four tight sets (including three tiebreaks). In the ensuing final, he defeated No. 1 Rafael Nadal in four sets, thus denying Nadal's attempt for the distinction of being the only active men's tennis player to hold at least two titles at each of the four Grand Slam tournaments. The victory was his first win over Nadal in 13 attempts (having never won a set against him in their previous 12 meetings), and also made him the first man since Sergi Bruguera in 1993 to beat both of the top two seeds en route to a Grand Slam title. (Bruguera defeated No. 1 Pete Sampras and No. 2 Jim Courier at the 1993 French Open). This was also only the second time since 2005 that a player outside of the 'Big Four' (Federer, Nadal, Djokovic, and Murray) had won a Grand Slam title, and the first since Juan Martín del Potro won the US Open in 2009. In addition, Wawrinka became the first player to defeat both Nadal and Djokovic in a single Grand Slam tournament. He is also the second Swiss man to win a Grand Slam singles title after Federer.

Playing for Switzerland in the first round of the Davis Cup against Serbia, he defeated Dusan Lajovic in four sets in the second rubber. Switzerland went on to win the tie 3–2 (after an unassailable 3–0 lead) to reach their first Davis Cup quarterfinal since 2004.

The pair appeared as friends though when they met for the Davis Cup final. In the final against France, Wawrinka gave his country the perfect start by defeating Jo-Wilfried Tsonga in four sets. Wawrinka then teamed up with Federer to win the doubles rubber and give Switzerland a 2–1 lead going into the final day. The match ended a sequence of four doubles rubbers losses for the pair, and it was their first win together on clay. Wawrinka did not play on the final day, as Federer sealed the tie, by beating Gasquet in straight sets for Switzerland's first Davis Cup title. With the win, Wawrinka became the first player since Andre Agassi in 1992 to win his first Grand Slam title and first Davis Cup in the same season.

Wawrinka next competed in the French Open, as the 8th seed. He beat Marsel İlhan and Dusan Lajovic in three and four sets, respectively, before beating Steve Johnson and Gilles Simon in straight sets to reach the quarterfinals, and defeated compatriot Roger Federer in straight sets to reach his first Roland Garros semifinal. This was also Wawrinka's first win over Federer in a major tournament. Winning in four sets against Jo-Wilfried Tsonga in the semifinals, he earned his second appearance in a Grand Slam final, this time against top seed Novak Djokovic. He defeated Djokovic in four sets, after being down a break in the fourth set and 0–40 in a subsequent game. He broke Djokovic's service twice in the set, reeling off six of the final seven games of the match. With this victory, Wawrinka claimed his second Grand Slam tournament title, and Djokovic failed to win a personal career Grand Slam. Wawrinka's French Open championship also denied Djokovic the 2015 calendar year Grand Slam, as Djokovic won all other Grand Slam tournaments that year. Mirroring his victory at the 2014 Australian Open, Wawrinka was seeded 8th at this tournament, defeated the 2nd and 1st seeds in the quarterfinals and finals, respectively, clinched the championship match in four sets, and rose five positions in the ATP rankings, back to the No. 4 position, which was his original position at the beginning of the year. This was also the 2nd time since Sergi Bruguera at the 1993 French Open that the champion defeated No. 1 (Novak Djokovic) and No. 2 (Roger Federer) players in the same grand slam (Wawrinka also accomplished this feat at the 2014 Australian Open). Wawrinka is the first man to win Roland Garros after losing in the first round in the previous year since Albert Costa in 2002, and the first former boys' champion to win the men's title since Mats Wilander in 1982.

Wawrinka was seeded 24th at the French Open. He won his first two matches against Jozef Kovalík and Cristian Garín before beating Grigor Dimitrov for the third time in the last four majors. He then defeated Stefanos Tsitsipas in the fourth in an 'epic' five setter that lasted 5 hours and 9 minutes (the final scoreline was 7–6, 5–7, 6–4, 3–6, 8–6) to advance to his first Grand Slam quarterfinal in two years. However, he was eliminated by Roger Federer, the third seed, in four close sets.

In 2013, he began working with new coach Magnus Norman, who was a former world No. 2 and coached Robin Söderling to two consecutive French Open finals and a Masters title. This partnership has been credited with tremendous improvement in Wawrinka's overall game, who qualified for the ATP World Tour Finals for the first time the same year and ended the year in Top 10 for the first time. The following 3 years Wawrinka won 1 Grand Slam, qualified for Tour Finals, and ended the year in Top 5 every season.

Norman is also credited with improvement in Wawrinka's mental toughness, as seen in his performance in important matches and was evident in his victories over Andy Murray at the 2013 US Open, and Novak Djokovic at the 2014 Australian Open (both were defending champions), as well as his improved consistency, culminating in his win over No. 1 Rafael Nadal at the 2014 Australian Open in which Wawrinka survived a fightback from Nadal to clinch the title. He also survived a fightback from No. 1 Novak Djokovic at the 2015 French Open final, being down one break of serve in the fourth set, before breaking Djokovic's service twice to clinch the title.

Despite his late-career successes, Wawrinka has been mired with inconsistency throughout his career. Illustrative of this is his record against players ranked No. 1 in the world. In Grand Slam finals, he holds a 3–0 record against No. 1 players but is 1–20 in all other matches against No. 1s, with that single victory coming in the semifinals of the 2017 French Open against Andy Murray. This, combined with the 11 consecutive finals won, has given Wawrinka the reputation of being a "big-match player". Furthermore, Wawrinka is one of only two players in the Open Era to have won three Grand Slam singles titles, but never been ranked higher than No. 3, the other being Jan Kodeš.

Wawrinka and Novak Djokovic have played 25 times with Wawrinka trailing 6–19 (24.0%); however the two have contested numerous close matches and therefore it is considered a highly competitive rivalry since 2013. Wawrinka defeated Djokovic at all three Grand Slam tournaments which he won, including two finals matches. Wawrinka and Djokovic played in three consecutive Australian Opens (2013–2015), with each match going to five sets, a five-set match at the 2013 US Open, and a five set match at the 2006 Davis Cup. At the 2013 Australian Open, the two played each other in the fourth round with Djokovic winning 12–10 in the fifth set. Later that year at the US Open in what was Wawrinka's first career Grand Slam semifinal appearance, Djokovic won 6–4 in the fifth set. At the 2014 Australian Open quarterfinals, Wawrinka won 9–7 in the fifth set, breaking Djokovic's run of 14 consecutive semifinals in Grand Slam tournaments and ending Djokovic's 25 match winning streak at the Australian Open. Djokovic got revenge at the 2015 Australian Open, winning 6–0 in the fifth set. In the 2015 French Open final, Wawrinka defeated Djokovic in four sets to claim his second Grand Slam title and thereby become the only player apart from Roger Federer to defeat Djokovic in the Australian Open and the French Open. Wawrinka defeated Djokovic in four sets to win the 2016 US Open singles title. At the 2019 US Open, Wawrinka once again defeated Djokovic (who at the time had won 36 of his last 37 Grand Slam matches) after Djokovic retied injured trailing two sets to love. Contrary to most high-profile rivalries, they have played doubles together and maintain a close friendship.

Despite Djokovic's 19–6 overall record against Wawrinka, Wawrinka leads Djokovic 2–0 in Grand Slam finals and 3–2 in all ATP finals. Their overall head-to-head in Grand Slam matches is also split at 4–4. During Djokovic's run of twelve appearances at Grand Slam finals from 2014 Wimbledon through the 2016 Wimbledon, his only two losses came at the hands of Wawrinka. Moreover, in Djokovic's 25 Grand Slam championship matches, Wawrinka is the only opponent he has not defeated and Wawrinka is also the only opponent outside the Big Four who has defeated him.

Wawrinka and his compatriot Roger Federer have played each other 26 times with Wawrinka trailing 3–23 (11.5%). Federer leads 7–1 in Grand Slam tournaments, 17–0 on hard courts, 1–0 on grass courts and 4–3 on clay courts. While the rivalry is one-sided in Federer's favour, the two of them have contested some close matches such as the 2014 Monte Carlo Rolex Masters final in which Wawrinka came from behind a set to defeat Federer in three sets to win his first Masters 1000 title. Wawrinka also defeated Federer in straight sets during the 2015 French Open quarterfinals en route to winning his first ever French Open title although Federer then reversed it with a straight sets victory in the 2015 US Open semifinals. Federer defeated Wawrinka in five sets in the 2017 Australian Open semifinals en route to his 18th major title. Other close matches include the 2012 Shanghai Masters and the 2013 Indian Wells Masters, both of which Federer won in three sets, the 2014 Wimbledon quarterfinal which Federer won in four sets and the 2014 ATP World Tour Finals in which Federer won in three sets after saving four match points. The duo's most recent encounter took place at 2019 French Open with Federer prevailing in four sets. Despite their on-court rivalry, they are close friends off court and they have played doubles together on numerous occasions, most notably when they won the doubles Olympic Gold at the 2008 Beijing Olympics and when winning the 2014 Davis Cup.

Wawrinka and Andy Murray have played 19 times with Wawrinka trailing 8–12 (40.0%). Murray leads 8–4 on hard courts and 3–0 on grass courts while Wawrinka leads 4–1 on clay courts. They have also met 6 times in Grand Slam tournaments and result is tied 3–3. They have contested some close matches and two of their most notable matches were in the 2009 Wimbledon fourth round which Murray won in five sets and was the first men's match to be played under the Wimbledon roof, having the latest finish for a Wimbledon match at the time., and the 2017 French Open semi-final, where Wawrinka prevailed in a five-set thriller that lasted over four hours. Wawrinka also ended Murray's title defence at the 2013 US Open quarterfinals with a comfortable straight sets victory. Other close matches the two have contested include the 2010 US Open which Wawrinka won in four sets and was Murray's last defeat before a grand Slam quarterfinal until the 2015 US Open, the 2008 Canada Open and 2011 Shanghai Masters, both of which Murray won in three sets.

While Murray has led the majority of the rivalry, Wawrinka won their first two matches and beat Murray three consecutive times between 2013 and 2015, winning all of them in straight sets, until Murray ended the winning streak at the 2016 French Open, beating the defending champion Wawrinka in four sets. In the 2018 Eastbourne International, Murray won in straight sets. Around this time Wawrinka was identified by some, including Djokovic, as a potential contender to turn the Big Four tennis quartet into a "Big Five", although Wawrinka himself downplayed those suggestions, stating that he was still far behind the others. Their most recent encounter was in the final of the European open 2019 in which Murray prevailed coming back from a set and a break down to win his first title since 2017 and his hip surgery.

Wawrinka and Rafael Nadal have played 20 times with Wawrinka trailing 3–17 (15.0%) against Nadal. Although this rivalry has less significance than rivalries with the other members of the Big Four, the pair have met in several prestigious tournaments. The rivalry saw Nadal winning the first 12 encounters, all in straight sets, including 2 finals, one of which is a Masters 1000 final at Madrid in 2013. However, since Wawrinka's breakthrough season in 2013 the head to head has been slightly more even (3–6) from 2014 onward. Wawrinka scored his first win against Nadal in their first Grand Slam final, the 2014 Australian Open final in 4 sets, denying Nadal's double career slam. It was also the only match between the pair not resulting in a straight set win for either player. Nadal won their second Grand Slam final, at the 2017 French Open.

Wawrinka was born in Switzerland to a German father and Swiss mother. He holds dual Swiss–German citizenship. His father Wolfram Wawrinka, a farmer and social worker, is German of Czech ancestry. Wawrinka's paternal great-grandfather originated from Silesia — the border region between Poland and the former Czechoslovakia — the surname originating with the Polish language. Wawrinka's mother, Isabelle, an educator, is Swiss. His mother works as a biodynamic farmer helping disabled people and took over the running of his parents' farm, "Ferme du Château", near Lausanne, which is connected with the castle of Saint-Barthélemy. The farm assists people with mild to moderate intellectual disabilities, and people with depression or drug and alcohol problems. Here Wawrinka grew up with his elder brother, Jonathan, and his two younger sisters, Djanaée and Naélla, who are students and tennis players. Wawrinka attended the Rudolf Steiner School in Crissier.

Wawrinka started off 2011 by defeating No. 6 Tomáš Berdych along the way to claiming the Chennai Open crown. Wawrinka beat Xavier Malisse in the final in three sets. He advanced to the quarterfinals of the 2011 Australian Open, after defeating Andy Roddick in three sets to set up an all-Swiss quarterfinal with Roger Federer, which he lost in straight sets. He also came back from two sets and a break down to defeat Jo-Wilfried Tsonga in the third round of the French Open, before being defeated by Federer once more. Wawrinka was defeated by Simone Bolelli in the second round of Wimbledon and Donald Young at the same stage of the US Open.

Wawrinka won the fourth title of his career at the Portugal Open, where he defeated the top seed and No. 4 David Ferrer. This was his first title since January 2011.

Wawrinka started his 2010 season by reaching the final of the Chennai Open, losing to Marin Čilić in two tie-breaks. This was Wawrinka's fifth consecutive loss in an ATP final. He reached the third round at the Australian Open, losing to Čilić again. Wawrinka returned to the ATP Tour at the Sony Ericsson Open after his wife gave birth to their daughter. He defeated Kevin Anderson, before losing to Mikhail Youzhny in the third round. He started his clay-court season in Casablanca at the 2010 Grand Prix Hassan II. After receiving a first-round bye, he defeated Slovakian qualifier Martin Kližan in the second round. In the quarterfinals, he defeated wildcard Reda El Amrani in straight sets. In the semifinals, he defeated Italian Potito Starace in three sets to advance to his second ATP final of 2010. In the final, he defeated Romanian Victor Hănescu in straight sets to win his second ATP Tournament. With this tournament win, he snapped a five-match losing streak in ATP finals and a 3½-year title drought. It was also the first professional singles final Wawrinka won, as his previous ATP victory occurred due to a retirement.

Wawrinka started his season at the Chennai Open where he was the two-time defending champion and 1st seed. He started against young wildcard Andrey Rublev. He won in straight sets. Then he played 5th seed Guillermo García-López. He also won in straight sets. In the semifinal he played against 3rd seed and good friend Benoît Paire. He won another straight sets match. In the final he played 8th seed and young talent Borna Ćorić. He successfully defended his title without dropping a set the entire tournament.

Wawrinka considers clay his best and favorite surface, and his serve and backhand his best shots. John McEnroe once said that Wawrinka has one of the most powerful backhands ever, and in 2009 described him as having "the best one-handed backhand in the game." He has been described by The Economist as "Tennis's great latecomer", owing to finding success late in his career. Prior to the 2014 French Open, he requested and the ATP granted a formal change in his name from "Stanislas Wawrinka" to "Stan Wawrinka", stating that he plans to use the abbreviated name in tournament draws and press conferences.

As of 2009, Wawrinka lived in Saint-Barthélemy, about 20 km (12 mi) north of Lausanne, with his wife Ilham Vuilloud, a Swiss television presenter and former fashion model. They married on 15 December 2009. Vuilloud gave birth to the couple's child, a girl named Alexia, on 12 February 2010. On 4 January 2011, Swiss media reported that Wawrinka separated from the family, less than one year after his daughter's birth. The couple later reconciled, but on 19 April 2015 Wawrinka posted a statement on his Facebook page announcing their divorce. The following day, Vuilloud strongly disputed Wawrinka's version of events.

Wawrinka is a three-time Grand Slam tournament winner, Olympic champion and Davis Cup champion for his country. He achieved a Top 10 ranking by the ATP for the first time on 12 May 2008, and first reached a career peak of world No. 3 on 27 January 2014, at the same time as he became the Swiss No. 1.

At the US Open, Wawrinka defeated Rajeev Ram and Mariano Puerta in five sets before losing in the third round to Nicolás Massú. By the end of 2005, he hovered just inside the top 50.

Wawrinka turned professional in 2002 at the age of 17. He was coached from age eight until June 2010 by Dimitri Zavialoff.

Wawrinka started playing international junior events at age 14 and entered the satellite circuit the following year. In 2002 Wawrinka became professional. In 2003 he had his first steps on the tour and ended the year ranked No. 169. He compiled an outstanding junior career, winning the Junior French Open in 2003 and reaching as high as No. 7 in the junior world rankings in June 2003.

Stanislas Wawrinka (French: [stanislas vavʁiŋka] ; born 28 March 1985) is a Swiss professional tennis player. He reached a career-high Association of Tennis Professionals (ATP) world No. 3 singles ranking for the first time on 27 January 2014. His career highlights include three Grand Slam titles at the 2014 Australian Open, 2015 French Open and 2016 US Open, where he defeated the No. 1 player in the final on all three occasions, reaching the final of the 2017 French Open, winning an ATP Tour Masters 1000 title at the 2014 Monte-Carlo Masters, and reaching three other finals at 2008 Rome, 2013 Madrid and 2017 Indian Wells. As a competitor for Switzerland, Wawrinka won gold in doubles at the 2008 Beijing Olympics with teammate Roger Federer, and was also pivotal in the Swiss team's victory at the 2014 Davis Cup.

In the US Open, Wawrinka reached the fourth round, a stage he had never reached previously in a Grand Slam event, defeating 25th seed Marat Safin in straight sets in the second round. In the fourth round, he was ousted by Juan Ignacio Chela in five sets.

Wawrinka had his Grand Slam debut at the French Open. He won against 22nd seed and Olympic Gold Medalist Nicolás Massú in the first round, in four sets. In the second round, Wawrinka came from two sets down to defeat James Blake. His run ended in the third round losing in four sets to the eventual runner-up Mariano Puerta.

At the Australian Open, he made it to the fourth round. He lost a gruelling five-set thriller against Novak Djokovic which lasted just over five hours, finally losing in the 22nd game of the fifth set. "It definitely ranks right at the top", said Djokovic, after his victory over the Swiss. "One of the longest, most interesting, and most exciting matches I have played in my career."
