Canelo stuck with Mayweather for the first half of the fight. But after that, he seemed to get tired and, by the end, Mayweather was having his way with him. Shortly after the match ended, Canelo admitted that he simply couldn't keep up.

"I couldn't catch him," he said. "He was very elusive…I did not know how to get him. He is very intelligent. He's got a lot of experience. Honestly, I couldn't find him."
