====Mosley vs. Margarito====

Prior to one of the biggest fights of his career, Mosley began training with [[Naazim Richardson]]. Mosley regained the WBA (Super) welterweight title from [[Antonio Margarito]] on January 24, 2009, at the [[Staples Center]] in Los Angeles. Mosley, now 37 years old, came into the fight as a 4–1 underdog with the bookies<ref>{{cite news|url=http://www.lasvegassun.com/news/2009/jan/17/25-world-title-fight/ |title=Margarito-Mosley: The $25 world title fight – Saturday, Jan. 17, 2009 &#124; 2 a.m. |newspaper=Las Vegas Sun |access-date=March 22, 2010}}</ref> after Margarito had spectacularly stopped Cotto 6 months earlier. Prior to the bout, very few gave Mosley a chance of prevailing, with the prevailing view that Margarito was too strong and young for Mosley. The conventional wisdom was that this was a mismatch, which would end in a brutal retirement-forcing stoppage for "Sugar" Shane. A comparison of their last fights; the aforementioned destruction of Cotto by Margarito and a last-gasp knockout by Mosley in a hard twelve-round struggle against Mayorga did not bode well for Mosley. Some predicted a massacre. And it was – only it was Margarito that was ruthlessly clubbed about the ring, unable to land any meaningful shots.

Mosley eventually TKO'd Margarito in the ninth round, after appearing to win every round up until then, in a massive upset. Sugar Shane utterly dominated Margarito, using his superior hand speed, pinpoint accuracy, consistent body punching, countless huge right hands to the jaw and [[Grappling position#Stand-up positions|tying up]] when Margarito backed him into the ropes, to wear Margarito down and stop him—something that many seasoned boxing observers thought was nigh-on impossible. After knocking him down with a series of heavy overhand rights at the end of the eighth round, Margarito was unable to avoid punches during a heavy barrage from Mosley early on in the ninth, forcing the referee to step in as Margarito slumped to the canvas a second time. Margarito had never previously been stopped. It was a sensational win for Sugar Shane and propelled him back to the upper echelons of the [[welterweight]] division and the sport of Boxing, in addition to further cementing his legacy as one of the best fighters in his era.<ref>{{Cite news|url=http://www.secondsout.com/columns/thomas-hauser/antonio-margarito-and-the-handwrap-issue|title=Antonio Margarito and the Handwrap Issue|newspaper=SecondsOut Boxing News|access-date=2017-02-06|language=En}}</ref><ref>{{Cite web|url=https://www.espn.com/sports/boxing/columns/story?id=3858534&columnist=rafael_dan|title=Mosley looks stellar in upsetting Margarito|date=2009-01-25|website=ESPN.com|access-date=2017-02-06}}</ref>

The fight was marred in a controversy after Mosley's trainer, [[Naazim Richardson]] diligently spotted a gauze knuckle pad accessory in Margarito's hand wraps. [[California State Athletic Commission]] officials had Margarito re-wrap his hands and took the pad for testing: a state laboratory likened the substance to [[plaster of Paris]]. Margarito and trainer Javier Capetillo would be suspended for a year by CSAC: this effectively banned them from boxing across the United States, as suspensions in one state are usually also enforced by other commissions. Later investigations determined that Margarito was likely loading his gloves for several other fights as well, including his title win over Miguel Cotto.<ref>{{cite web|last=Christ |first=Scott |url=http://www.badlefthook.com/2009/1/25/735983/wrap-controversy-casts-clo |title=Wrap controversy casts cloud over Margarito's reputation |publisher=Bad Left Hook |date=January 25, 2009 |access-date=March 22, 2010}}</ref>

The fight was for Margarito's [[World Boxing Association|WBA]] title and the vacant [[Lineal Championship|Lineal]] welterweight championship of ''Cyber Boxing Zone (CBZ)''.<ref>{{cite web|url=http://www.cyberboxingzone.com/boxing/welter.htm|title=The Lineal Welterweight Champs|publisher=cyberboxingzone.com}}</ref> ''[[The Ring (magazine)|The Ring]]'' did not recognize this bout for its vacant welterweight championship despite the fact it pitted ''The Ring'' #1 ranked welterweight, Antonio Margarito, vs. ''[[The Ring (magazine)|The Ring]]'' #3 ranked welterweight, Shane Mosley. Coming in the bout, Margarito had just TKO'd the previous ''The Ring'' #1 ranked welterweight and current ''[[The Ring (magazine)|The Ring]]'' #2 ranked welterweight, [[Miguel Cotto]].<ref>{{cite web|url=http://www.boxingscene.com/margarito-mosley-welterweight-crown---17891|title=Margarito, Mosley, and The Welterweight Crown|last=Rold|first=Cliff|date=January 15, 2009|publisher=boxingscene.com}}</ref> After the fight, Mosley was named ''The Ring'''s #1 ranked welterweight.

====Mosley vs. Mayweather====
{{Main|Floyd Mayweather Jr. vs. Shane Mosley}}
It was announced that on May 1, 2010, Mosley would fight undefeated [[Floyd Mayweather Jr.]] Boxing purists had called for the fight for over ten years. Mosley was scheduled to fight [[List of WBC world champions|WBC champion]] [[Andre Berto]] in a unification fight, but Berto had to pull out after an [[2010 Haiti earthquake|Earthquake in Haiti]] killed some of his family members.<ref>{{Cite news|url=http://www.boxingnews24.com/2010/01/mayweather-vs-mosley-announcement-imminent-news/amp/|title=Mayweather vs. Mosley announcement imminent – News » Boxing News|date=2010-01-28|work=Boxing News 24|access-date=2017-10-08|language=en-US}}</ref> Mosley's WBA title was not on the line because Mayweather refused to pay WBA sanctioning fees.<ref>{{Cite news|url=http://bleacherreport.com/articles/335830-floyd-mayweather-and-shane-mosley-agree-to-terms-to-fight-may-1-2010|title=Floyd Mayweather and Shane Mosley Agree to Fight on May 1, 2010|last=Holloway|first=Clayton|work=Bleacher Report|access-date=2017-10-08|language=en-US}}</ref> On the fight night, Mosley stunned Mayweather with two right-hand shots in the second round. Mayweather recovered well and dominated the remainder of the fight with superior reflexes and his effective counter-punching style, eventually beating Mosley in a wide decision 119–109, 119–109, and 118–110 on the scorecards to win Mosley's ''lineal'' welterweight championship.<ref>{{Cite web|url=https://www.espn.com/sports/boxing/columns/story?id=5155050&columnist=rafael_dan|title='Money' silences critics with dazzling display|date=2010-05-02|website=ESPN.com|access-date=2017-02-06}}</ref><ref>{{Cite news|url=http://www.espn.co.uk/boxing/story/_/id/7160303/floyd-mayweather-victor-ortiz-fight-drives-more-one-million-buys|title=Mayweather-Ortiz fight drives 1.25 million buys|newspaper=ESPN.com|access-date=2017-02-06}}</ref>

On May 22, 2010, Mosley was stripped of his WBA (Super) welterweight title, due to not making a mandatory defense, which in turn made WBA Champion [[Vyacheslav Senchenko]] the sole WBA titlist in the welterweight division.<ref>{{Cite web|url=http://www.boxingscene.com/shane-mosley-stripped-senchenko-full-wba-champ--27982|title=Shane Mosley is Stripped, Senchenko Full WBA Champ – Boxing News|website=www.boxingscene.com|date=May 21, 2010 |language=en-us|access-date=2017-02-06}}</ref>
