Marcos Maidana

On 9 August 2016, Maidana officially announced his retirement from professional boxing at the age of 33, allegedly moving into an advisory role. Maidana wrote in a letter addressed to boxing friends on social media: "After a long time out of the ring and after giving it a lot of thought since my last fight I've decided to hang up the gloves for good. Probably my decision would not surprise much as I had given hints of it in the last few months. But at this time I am making it official." Maidana finished with a career record of 35 wins in 40 fights, 31 wins coming by way of knockout and 5 decision losses.

Broner exercised his contractual rematch clause on 15 January 2014 to fight Maidana in a rematch. He told ESPN, "My mind is set on war. I had a bad night. He was the better man that night, but he didn't beat me. He outhustled me. I respect everything. I respect him. But I'm ready to go back to war and get my belt back." After Maidana beat Broner, he became a candidate to fight Floyd Mayweather Jr. on 3 May on Showtime PPV. The other close candidate was Amir Khan. Maidana's manager Sebastian Contursi believed his fighter deserved a big money fight. ESPN reported the rematch could take place in April 2014 in California at the StubHub Center or again at the Alamodome.

In February 2014, despite interest in a bout with Amir Khan, Floyd Mayweather Jr. announced that he would fight Maidana on 3 May 2014, in a unification bout at MGM Grand Garden Arena, with Mayweather's WBC and The Ring welterweight titles at stake, as well as Maidana's WBA (Super) welterweight title. Maidana won the WBA title in December 2013 against Mayweather protégé, Adrien Broner. Mayweather tweeted the news the day after his 37th birthday. The Barclays Center in Brooklyn also made a case to showcase the fight. Mayweather explained why he chose Maidana, "Marcos Maidana's last performance immediately brought him to my attention. He is an extremely skilled fighter who brings knockout danger to the ring. I think this is a great fight for me and he deserves the opportunity to see if he can do what 45 others have tried to do before him – beat me." Maidana was a 12-to-1 underdog going into the fight.

On 10 July 2014, Mayweather made the announcement that a rematch with Maidana (35–4, 31 KOs) was confirmed. The fight was to take place on 13 September 2014, at the MGM Grand Garden Arena, with Mayweather's WBA (Super), WBC and The Ring welterweight titles at stake, as well as Mayweather's WBC light middleweight title. The fight was billed as "Mayhem".

Khan successfully defended his title for the third time against Maidana. Khan knocked Maidana down with a combination of 2 body shots in the first round. Maidana was saved by the bell but somehow regained composure and continued to battle on. Khan dominated the scoring until tiring around round 7. Maidana rallied and midway through round 10 stunned Khan with a heavy right hand. Maidana landed a series of follow up uppercuts and rights but could not drop Khan. Khan then rallied to win rounds 11 and 12 to solidify a unanimous points decision. The scores were 114–111, 114–111, and 113–112. Khan was open to a rematch. Khan landed 273 of 603 punches thrown (45%) and Maidana landed 156 of 767 thrown (20%). The fight was awarded Fight of the Year by the Boxing Writers Association of America.

In the first round, Maidana came out with ferocity as expected and proceeded to batter his older opponent around the ring. He landed multiple power punches, including an uppercut that opened a huge swelling over Morales' left eye which worsened over the course of the fight, and when the Mexican walked back to his corner having taken a large amount of punishment in the opening three minutes most observers felt their predictions were being fulfilled. The one-sided nature of the bout continued for the next couple of rounds, but then at the end of the third round Morales begin to fight back and landed a hard combination to the head of Maidana and the tide began to turn. From the fourth round onwards and although he was effectively fighting with one eye, Morales gave as good as he got and was landing the cleaner more effective shots, albeit occasionally being swarmed by the sheer number of punches being landed in return by the relentless Maidana. The fight became a see-saw affair and then, in the eighth round, Morales hit Maidana with a huge left hook that almost stopped the Argentine. The next couple of rounds continued in this fashion, with Maidana using his strength and stamina to bully Morales and the Mexican using his sharper punching and ring intelligence to land effective counters and combinations. The fight was fast turning into a modern classic. In the championship rounds, Morales seemed to tire and Maidana took advantage, overwhelming him with his strength and punishing the ageing warrior continually to the head and body. Maidana finished the fight much the stronger of the two and his late surge gave him the win on the scorecards, 116–112 twice with the third judge scoring the fight a draw, 114–114. Most of the 7,154 fans in attendance booed the decision. ESPN scored the fight 114–114.

On 29 November, it was announced that, whilst waiting for a big fight, Maidana would fight the largely unknown Mexican boxer Martin Ángel Martínez (13-3-1, 9 KOs) on 12 December at the Luna Park Stadium in Buenos Aires, for the vacant WBA Inter-Continental welterweight title. In front of over 7,000 local fans, Maidana won the fight by KO in the third round. Maidana started off slow, but picked up the pace in round 2 before landing a powerful left hook to body, dropping Martínez for the full 10 count. Maidana stated his intention to fight Paulie Malignaggi or Robert Guerrero next.

Maidana scored a TKO over welterweight contender Josesito Lopez in the sixth round of a 9 June 2013 fight. Maidana had injured his hip in the second round and Lopez capitalized, tagging his opponent with hard shots. Maidana was able to reverse the tide and hurt Lopez with an overhand right in the sixth round that dropped him to the canvas. Lopez later said that Maidana is the hardest puncher he ever faced.

In October 2013, it was announced that Adrien Broner would make his first defense of the WBA welterweight title against Maidana. Originally scheduled as a PPV fight, Golden Boy Promotions and Showtime Sports announced it would take place on regular Showtime on 14 December. The fight was due to take place at the MGM Grand arena, but later move to the Alamodome in San Antonio. Broner had stated before the fight that he did not take training camp seriously for the Malignaggi fight, and that he was going to make a statement in his first defense. There was a crowd of 11,312 at the Alamodome, with Broner a 5 to 1 betting favorite. From the opening bell, Maidana swarmed Broner, punishing him to the body and the head. In the second round, a left hook sent Broner down for the first time in his career. Broner recovered and seemed to be on the verge of taking control over a tiring Maidana, but a right to the body followed by a left hook to the head once again put Broner down in round 8. Following the knockdown, Maidana had a point deducted for a headbutt. Maidana punished Broner for the remainder of the fight, winning the fight via unanimous decision and giving Broner his first loss as a professional. The judges scored the fight 115–110, 116–109, and 117–109 in favour of Maidana. Maidana had now won four consecutive fights under the tutelage of boxing trainer Robert Garcia. Broner immediately left the ring following the announcement. Fans booed and threw drinks at Broner as he made his way back to his dressing room.

In front of a sold-out crowd of 16,268, in what was one of his toughest fights, Mayweather won the bout via majority decision, with scores of 114–114, 117–111, and 116–112. Maidana came out aggressive and maintained that stance throughout the fight forcing Mayweather to engage. CompuBox revealed that Mayweather was hit more times than any of his previous 38 bouts that have been covered by them. Mayweather landed 230 of his 426 punches thrown (54%) while Maidana landed 221 of 858 (26%). Many times in the fight Maidana threw shots at different angles, forcing Mayweather against the ropes. According to Mayweather in the post fight interview, Maidana's aggressive approach made him change his style of fighting.

In front of 16,144 at the MGM Grand, Mayweather defeated Maidana via unanimous decision. Unlike the first fight, Mayweather came out better prepared for Maidana's style. The final judges' scores were 115–112, 116–111, and 116–111. ESPN scored it wider for Mayweather at 119–108. Despite a moment at the end of round 3 where Maidana rocked Floyd, Mayweather did not allow Maidana to land any overhand right, with the punch stats showing Maidana connecting 128 of 572 shots (22%). Mayweather had 51% connect rate landing 166 of 326.

In December 2011 it was announced that Maidana would move up to welterweight to fight former WBC and IBF light welterweight champion Devon Alexander, who was also moving up in weight, on 25 February 2012, at the Scottrade Center in St. Louis, Missouri in a 10-round bout. Alexander was the betting favourite going into the bout. Maidana seemed uncomfortable in his first fight at the new weight as Alexander dominated the fight and went on to win a lopsided unanimous decision. The three judges scored the fight 100–90, 100–90, and 99–91 for Alexander. Alexander landed 168 punches compared to the 93 landed by Maidana. Speaking of the loss, Maidana said, "I was slower. He was very fast and complicated."

On 10 February 2011, Golden Boy promoter Richard Schaefer announced that a deal was reached for Maidana to next fight former three-weight world champion Érik Moralez (51-6, 35 KOs) on 9 April at the MGM Grand in Las Vegas on HBO PPV billed as 'Action Heroes'.

After his fight with Ortiz, it was rumoured that Maidana would face British boxer, and WBA super lightweight champion, Amir Khan, who won the title after defeating Andreas Kotelnik. However, Khan opted for Paulie Malignaggi as his next opponent. As a result, Maidana was scheduled to fight on 27 March 2010, against Victor Cayo, whose record, at that time, was 24-0 with 75% of victories coming by way of knockout. Maidana knocked out the undefeated Cayo in the sixth round to retain his interim WBA super lightweight title and improve his record to 28-1, with 27 knockouts.

After failing to secure a fight with Timothy Bradley, Maidana fought and defeated DeMarcus Corley in August 2010. Despite knocking Corley down in the seventh round, Maidana had to go the distance for only the third time in his career, eventually securing the victory via unanimous decision 117–110, 117–110, and 115–112. Even with the knockdown, many believed the fight was close. By round 11, Maidana was tired and both fighters traded in the final round.

On 2 February 2009, Maidana challenged for his first world title, the WBA super lightweight championship against Andreas Kotelnik at the StadtHalle in Rostock, Germany. Kotelnik beat Maidana via controversial split decision, with the judges scoring the fight 115–114, 113–115, and 115–113 in Kotelnik's favor. Maidana was credited with landing 342 of 1241 punches thrown (28%), with 259 of them being power punches and Kotelnik was more accurate in landing 229 of his 655 thrown (35%).

Maidana's first fight in the United States was against Victor Ortíz, that took place on June 27, 2009 for the Interim WBA super lightweight title. Ortiz entered the fight with an eight-fight knockout streak. Both Ortiz and Maidana were knocked down in the first round. Ortiz knocked Maidana to the canvas twice in the second round. Ortiz suffered a cut in the fifth round and was knocked down in the sixth. The fight was stopped when the ringside physician would not let Ortiz continue to fight. Many in the boxing media, including HBO, chastised Ortiz for not wanting to continue in the fight.

Broner later apologized, saying, "I'm sorry for running out on all the fans after my fight. That was wrong of me as a fighter." Maidana said he was open to a rematch if it made sense. Broner later said, "I'll tell you one thing: Make a rematch. I don't need a warm-up fight. I want a rematch." Maidana landed 269 of 964 total punches (28%) and 231 of 663 power shots (35%). Broner connected on 149 of 400 total punches (37%) and 122 of 292 power shots (42%). Showtime Executive Vice President Stephen Espinoza announced the fight drew 1.3 million viewers, putting it as the third-highest rated fight for the network since it began keeping track of individual fights in 2009.

Maidana started his career in 2004 before turning 21 years old. He fought his first 18 fights in his native Argentina over two years, winning all, including 17 via stoppage. On his 18th bout, he won the WBA Fedelatin super lightweight title. Over the next year, Maidana only fought once in Argentina, five times in Germany and once in Panama. At the end of 2008, Maidana had a professional record of 25-0, with 24 stoppages.

Marcos René Maidana (born 17 July 1983) is an Argentine former professional boxer who competed from 2004 to 2014. He was a world champion in two weight classes, having held the WBA (Regular) super lightweight title from 2011 to 2012, and the WBA welterweight title from 2013 to 2014. A versatile brawler in the ring, Maidana was well known for his formidable punching power, and was never stopped in any of his five losses. He famously outbrawled and withstood punishing blows from Floyd Mayweather, Jr. during their first bout, but lost to Mayweather via majority decision.

Maidana was scheduled to defend his title 27 August 2011, against Robert Guerrero, but Guerrero suffered a shoulder injury less than two weeks before the fight. On 8 September, Russian boxer Petr Petrov (29-2-2, 13 KOs) was selected as Maidana's homecoming opponent for 23 September at Sociedad Alemana de Villa Ballester in Buenos Aires, which would also mark the bout as his first defence of the WBA (Regular) title. Petrov came into the bout having never been stopped as a professional. Breidis Prescott, who was scheduled to fight Paul McCloskey in September in a title eliminator, stated he would have put himself forward to replace Guerrero, and knocked Maidana out. Maidana became the first boxer to stop Petrov inside the distance and successfully retained his WBA title in round 4 of a one-sided fight. Petrov was in survival mode from the opening bell, trying to clinch. By round 3, Maidana began to see his punches land more and eventually dropped Petrov in round 4. Petrov got up and became a more defensive fighter for the remainder of the round until the final 30 seconds when Maidana landed a barrage of punches against the ropes, dropping Petrov again. The referee began the count, but almost immediately waived the count.

In July 2012, Showtime announced that Maidana would fight Jesus Soto Karass (26-7-3, 17 KOs) on the Saul Álvarez vs. Josesito Lopez undercard at the MGM Grand in Las Vegas on 15 September. Maidana won the fight by eighth-round TKO in a back-and-forth slugfest. Both boxers started off fast while trading blows. Maidana looked to set up his attack behind a jab. Midway through the fight, Maidana began to tire and Karass took over. In round 7, Maidana finally had a point taken off for continuing to hit on the break. Maidana landed a right hand, dropping Karass. In round 8, Maidana continued to attack Karass against the ropes before referee Kenny Bayliss stopped the fight. According to CompuBox Stats, Maidana landed 213 of 539 punches thrown (40%) and Karass landed 179 of his 748 thrown.
