MGM Grand, Las Vegas - Floyd Mayweather Jr. (42-0, 26KOs) knocked out Victor Ortiz (29-3, 22KOs) in the fourth round to capture the WBC welterweight title.

The first minute of the fight was a clear indicator that Mayweather's speed was still there and he was landing accurate punches while making Ortiz miss his counters. In the second round, Mayweather stayed true to his promise and he did exchange with Ortiz in spurts. Ortiz would rush in and get Mayweather against the ropes while firing punches, but he missed most of his punches. Mayweather's counters were accurate and hitting the target almost every time. Mayweather was picking him off in the third round and blocking almost everything in return.

Mayweather started unloading at the start of the fourth round. Ortiz was able to fight him off. Ortiz pinned Mayweathr against the ropes and let his hands go, but most of the punches didn't land clean. Near the end of the fourth, Ortiz was landing on Mayweather against the ropes and appeared to hit him with an elbow. Referee Joe Cortez stopped the action to take a point away from Ortiz. When Ortiz went to hug Mayweather to apologize, Mayweather blasted him with two hard shots as referee Joe Cortez appeared to be giving Ortiz some type of instructions. Ortiz went down and took the full count.

Editor's Note: After several replays aired in the arena, Ortiz jumped in and hit Mayweather with his head. At the point of the stoppage, Cortez appeared to be instructing the corner of Ortiz.
