Manny Pacquiao Beats Keith Thurman Reaction! Manny Pacquiao becomes the WBA welterweight champion of the world by winning a 12 round split decision over Keith Thurman! I had picked Thurman to win the fight going in. I just felt he was the better boxer. I was proven wrong! My personal score may have been closer than most, but I still had Pacquiao beating Thurman. I have to tip my hat to Manny Pacquiao for beating Keith Thurman who I also have to tip my hat to for showing humility in defeat. It’s a trait we see far too little of in boxing.
