Floyd Mayweather Jr. vs. Victor Ortiz

Floyd Mayweather Jr. vs. Victor Ortiz, billed as Star Power, was a championship fight for Ortiz's WBC welterweight title. The bout was held on September 17, 2011, at the MGM Grand in Paradise, Nevada, Nevada and televised via HBO PPV. As a part of a split-site doubleheader, the broadcast also featured the Saul Alvarez vs. Alfonso Gomez light middleweight championship bout taking place at the Staples Center in Los Angeles, California.

The fight
From round one, Mayweather used his speed, skills and accurate right hand to tag Ortiz repeatedly. Mayweather seemed in control through the first three rounds (judges scores: 30–27, 30–27, 29–28 for Mayweather), but in the fourth round, Ortiz found some success, landing a few shots and stinging Mayweather before backing him into the corner. Ortiz hit Mayweather in the face with an apparently intentional headbutt, busting open a cut on the inside and outside of Mayweather's mouth. Referee Joe Cortez immediately called timeout and penalised Ortiz a point for the foul. Ortiz, seemingly acknowledging his wrongdoing, hugged and kissed Mayweather in the corner. Cortez motioned the fighters back together to resume the fight. The fighters touched gloves and Mayweather seemed to half-heartedly return another hug from Ortiz. Then, with Cortez looking away from Mayweather, and as the fighters separated from the hug, Mayweather caught Ortiz with a left hook. Ortiz was stunned by the punch and, still not raising his hands to defend himself, was hit with a flush right to the face. Ortiz dropped straight onto the canvas and was unable to beat Cortez's count.

"In the ring, you have to protect yourself at all times," Mayweather said. "After it happened, we touched gloves and we were back to fighting and then I threw the left hook and right hand after the break. You just gotta protect yourself at all times." After the interviewer Larry Merchant pressed Mayweather on whether or not what he did was unsportsmanlike, Mayweather told the interviewer he never gives him a fair shake and should be fired.

Fight earnings
Mayweather was paid a guaranteed $25 million, which could have gone as high as $40 million depending on the pay per view numbers, and Ortiz was paid $2 million.
