Manny Pacquiao vs. Timothy Bradley, billed as “Perfect Storm“, was a welterweight title boxing match held on June 9, 2012, at the MGM Grand Garden Arena in Paradise, Nevada. After 12 rounds, Bradley won a highly controversial split decision to take the WBO welterweight title. Pacquiao came into the fight following a controversial November 2011 majority decision victory in Manny Pacquiao vs. Juan Manuel Marquez III. He brought with him world championships in eight different weight classes—a feat unmatched by anyone.
After fight negotiations between Pacquiao and Floyd Mayweather, Jr., ended without coming to terms, Mayweather opted to challenge junior middleweight titlist Miguel Cotto on May 5. Cotto had also been in the running to face Pacquiao in a rematch, but Pacquiao and Cotto could not agree on the weight for the fight. Pacquiao wanted the 147-pound welterweight limit, which Cotto said was too low for him, and he accepted a fight with Mayweather. Also in the running to face Pacquiao were Lamont Peterson and Juan Manuel Marquez. Ultimately, it was Timothy Bradley who came to terms, agreeing to move up a weight class to challenge Pacquiao for his title.
Bradley came into the fight with a somewhat lower profile than a typical Pacquiao opponent. In January 2011, he won a 10th-round technical decision in a junior welterweight title unification bout against Devon Alexander. Previously, he had beaten then world-champion Lamont Peterson to claim the title. After the fight with Alexander, Bradley rejected an offer to fight Amir Khanand further unify the 140-pound division. He signed with Top Rank and was given a co-feature slot on the Pacquiao-Marquez III pay-per-view card in November. In his match, Bradley beat former lightweight champion Joel Casamayor in an eight-round fight.
Prior to the Pacquiao fight, Bradley was ranked as one of the top 10 pound for pound fighters in the world. In a show of confidence, Bradley had “rematch” posters printed up, implying he would win the fight.
