Floyd Mayweather Jr. at Wednesday’s news conference touched on the psychological element of his May 2 fight against Manny Pacquiao at MGM Grand in Las Vegas (on HBO pay-per-view, Showtime pay-per-view). He intimated he has the edge in this department.

“One thing I do know about any sport, when you lose, it’s in your mind,” Mayweather said at Nokia Theatre in Los Angeles. “If you lost once, it’s in your mind. If you lost twice, it’s in your mind. From day one, I was always taught to be a winner. No matter what, be a winner, push yourself to the limit, stay focused and be the best that you can be.”

It was Mayweather’s way of reminding the more than 600 reporters in attendance that while Pacquiao (57-5-2, 38 KOs) has lost more than once, he is undefeated at 47-0 with 26 knockouts.
