According to Sky Sports, Pacquiao trained for 12 rounds using his left hand ahead of his fight with Mayweather Jr.

"It's all about usage, muscle memory... [Pacquiao and Mayweather] will be equal at some point [in the bout]. Manny's been favoring the right side so much now, I need to bring the left back," Roach said to LA Times (via Sky Sports).

The trainer stated Pacquiao did not use his right hand at all during the sparring.

Two years ago, Pacquiao was defeated by Juan Manuel Marquez and Timothy Bradley, however, the southpaw made a roaring comeback by defeating the American.
