A gold medal in the 2011 individual competition (they also compete for team titles) at the WSB secured champions in 5 WSB weight classes the first Olympic slots, so participation in WSB saw Warren's first near miss at qualifying (only top 2 ranked boxers after team competition selected for individual title fight). Warren won the 2011 US Olympic Trials and came home with the Bronze after the 2011 AIBA World Championships, securing his place in a 3rd Olympics, unprecedented for an American boxer, at only 25 years old. On August 3, 2012 at the London Olympics, Rau'shee Warren failed to get past the first round of the brackets yet again for the third time of his amateur career losing to Nordine Oubaali of France in a close decision of 19-18. Warren made his long-awaited professional debut on November 9, 2012, winning a four-round unanimous decision over Luis Rivera. Having won thirteen of his first fourteen fights (the only blemish being a three-round no contest against Javier Gallo on December 12, 2014), Warren attempted to win his first world championship—the WBA (Super) and vacant IBO bantamweight titles—on August 2, 2015, but lost a debatable split decision to Juan Carlos Payano. In a rematch with Payano on June 18, 2016, Warren gained revenge by winning both titles with a majority decision. However, Warren lost in his first defense to Zhanat Zhakiyanov by split decision.
