WBA welterweight champion Marcos Maidana (35-3, 31KOs) is looking for another upset victory when he faces Floyd Mayweather Jr. (45-0, 26KOs) on May 3rd from the MGM Grand in Las Vegas. Last December Maidana had a very big upset win with a twelve round unanimous decision over previously undefeated Adrien Broner in San Antonio.

"I respect him very much as a boxer. He chose me. He must know that I earned this position, that I deserved the opportunity. I earned it with my last four fights. To beat him, it is necessary to fight with everything. Robert García, my trainer in the United States, has been a big help to me. In the last fight, he made corrections [with me]," Maidana said.

"I wanted to earn this fight to remain in the history of Argentine boxing. That's why I wanted this fight very much. It is a very big opportunity for me. I believe that with the type of punches that I throw, I can knock him out."
