Trainer Freddie Roach promised "a whole new ballgame" for Tim Bradley in an April 12 rematch with Manny Pacquiao, whom Bradley beat by split decision in June 2012.

Roach's assertion was made on Saturday night just after he and Pacquiao (54-5-2, 38 knockouts) had landed at Los Angeles International Airport from the Philippines, where they were preparing for the return bout with Bradley (31-0, 12 KOs).

"Please tell Mr. Bradley it's a whole new ballgame," said Roach, who will continue Pacquiao's training at the Wild Card Boxing Club in Hollywood, Calif. "Manny means business this time." 

Pacquiao, who turned 35 in December, is coming off November's unanimous decision over former 140-pound titleholder Brandon Rios, who made his welterweight debut.

In victory, Pacquiao rebounded from his loss to Bradley as well as a sixth-round knockout loss to Juan Manuel Marquez in December of that year.

The 30-year-old Bradley won his last two fights by rising from a 12th-round knockdown to unanimously decision Ruslan Provodnikov in March of last year before earning October's split decision over Marquez, who is 1-2-1 against Pacquiao.

"It's great to be back in Los Angeles," said Pacquiao. "I can't wait to begin training at Wild Card. I have really missed it."
