Floyd Mayweather Jr. vs. Shane Mosley, billed as Who R U Picking? '', was a boxing welterweight non-title superfight, in which Mayweather Jr. won by unanimous decision with two judges scoring it 119–109 and one judge scoring it 118–110. The bout was held on May 1, 2010, before a "sellout" crowd of 15,117 at the MGM Grand Garden Arena in Las Vegas, Nevada, United States. Boxing greats Muhammad Ali and Mike Tyson were among a long list of celebrities in attendance. The match was put together after Andre Berto pulled out of his scheduled January 30 unification bout against Mosley. Build up
Talk about a fight between Mayweather and Mosley went back as far as 1999. However the first serious talk of fight between the fighters came after Floyd Mayweather's win over Juan Manuel Marquez, when the two fighters confronted each other and started shoving and insulting each other. However following this incident each fighter went his own way, only to meet up again. Shane Mosley was scheduled to face Andre Berto for a WBC and WBA Welterweight title unification bout on January 30, 2010. However, the fight (and entire undercard) was called off on January 18, 2010, due to an earthquake in Haiti and Berto losing several family members in the disaster. Negotiations for a proposed matchup between Mosley and Floyd Mayweather Jr. immediately began afterwards, ending with both sides agreeing to a set date of May 1, 2010, at the MGM Grand Garden Arena in Las Vegas, Nevada. The fight was billed "Who R U Picking?" Pre-fight hype
The earliest pre-fight hype came after Manny Pacquiao's fight with Joshua Clottey on March 13, 2010, when HBO aired a brief interview, confrontational-styled show entitled, "Face Off" with Max Kellerman hosting and leading the conversation. However the first major pre-fight hype took part when HBO produced a four-part prelude of their show 24/7. The series, titled Mayweather-Mosley 24/7, aired installments all throughout April 2010. The series focused on each fighter's training and preparation for the bout. For Mosley, the fight was very symbolic, and a way to show he is the best boxer in the world. For Mayweather, the fight was seen as just business, and Mosley as just another fighter. During one installment of Mayweather-Mosley 24/7, Mayweather proclaimed himself the greatest boxer of all time, better than Sugar Ray Robinson and Muhammad Ali, and made light of Mosley's skill. On the night of the fight one commentator called it "the most highly anticipated welterweight matchup since Sugar Ray Leonard stopped Thomas Hearns in the 14th round in 1981." Drug testing
Both Floyd Mayweather Jr. and Shane Mosley agreed to Olympic style drug testing for this fight, which included random sampling of blood and urine. This was the first fight in the United States to undergo these conditions. This style of drug testing was promoted from Mayweather due to his purported concern of the health of many fighters who face medical problems later in life due to drug use, as well as a way to make clear no cheating, imagined or otherwise, is taking place. Mayweather first proposed this when negotiations with Manny Pacquiao first took place in early 2010; they had both agreed to random urine testing and three blood tests, but Mayweather also demanded additional random blood testing, even though that is not required under the rules of the Nevada State Athletic Commission, and the fight ultimately fell apart. After alleging, without evidence, that Pacquiao used performance-enhancing drugs, Mayweather was required to pay Pacquiao a seven-figure settlement after Pacquiao sued him for those unsubstantiated claims. The fight
Entering the fight, Mayweather was a 1:4 favorite. Mosley started the match strong, winning round one. Round two belonged to Mosley once again as he hurt then buckled Mayweather's knees with powerful rights. Mayweather appeared to be in trouble for the first time in his career, but stayed on his feet. The close calls inspired the crowd to break into a chant of "Mosley! Mosley! Mosley!" When later asked how he survived the onslaught Mayweather replied, "it's a contact sport, and you're going to get hit. You got to suck it up and keep on fighting." After the trying second round, Mayweather bounced back with quick, precise punching, and avoided further trouble. He picked up his offense and controlled round three and four with fast combinations and low body jabs. A strong right in the fourth sent Mosley reeling. As the fight progressed, Mosley began to slow down. In the middle rounds, he backed off on offense and Mayweather took advantage by picking up points with non-damaging hits. By the seventh round, Mosley look winded. In the eighth, he became frustrated and received a referee warning after it appeared he tried to toss Mayweather to the ground in a wrestling-style move. By the end of ninth, Mosley had a "look of resignation on his face" as he walked back to his corner. Mayweather ending up losing only the second round, according to the judges' scorecards, winning the 12 round fight by unanimous decision. Two judges had the final margin at 119–109, while the third had it at 118–108. The win improved Mayweather to 41–0 in his career, while dropping Mosley to 46–6. After the fight, Mosley said neck tightness inhibited his fight. "I tried to move around, but he was too quick and I was too tight ... I thought I had to knock him out [early]". "I couldn't adjust and he did", Mosley added. Mayweather remarked, "I came here tonight to give the fans what they wanted to see: a toe-to-toe battle. It wasn't the same style, but I wanted to be aggressive and I knew I could do it." He said he was ready to take on Manny Pacquiao, if he "wants to fight" and "will take the blood and urine tests".
