Thomas & Mack Center, Las Vegas - Timothy Bradley advanced his claim to be regarded as one of the world's best by beating Juan Manuel Marquez in Las Vegas on Saturday night. Bradley thwarted Marquez's attempt to win his fifth “world” title by coming on in the second half of the fight to win. It was another close decision for Bradley, who was a hotly disputed winner over Manny Pacquiao two fights ago. He retained the WBO belt he won in that bout. The pro-Marquez crowd booed loudly when it was announced that Bradley had won 116-112 and 115-113 on two cards. The third judge had Marquez winning 115-113.
