LAS VEGAS — Tim Bradley didn't need big power to beat Manny Pacquiao after all.

Bradley won a contested split decision over Pacquiao, handing the Filipino superstar his first defeat in seven years. It didn't come easy and it wasn't without controversy, with the pro-Pacquiao crowd at MGM Grand Garden Arena booing the decision loudly.

Pacquiao landed more punches — 253 to 159 in 12 rounds, according to ringside stats — and seemingly harder punches. Bradley won 115-113 on two judges' scorecards and was behind by the same margin on a third. The Associated Press had Pacquiao winning 117-111.

Pacquiao (54-4-2) used his power to hurt Bradley in the early rounds. But Bradley (29-0) changed tactics in the middle rounds and used his boxing skills to win enough rounds to take the WBO welterweight title.

"I thought I won the fight," said Bradley, who is from Palm Springs, Calif., and was a 5-1 underdog. "I didn't think he was as good as everyone says he was. I didn't feel his power."

Promoter Bob Arum, who has contracts with both fighters, said, "Can you believe that? Unbelievable. I went over to Bradley before the decision and he said, 'I tried hard but I couldn't beat the guy.' "

Pacquiao said, "I did my best. I guess my best wasn't good enough."

Notes

• Pacquiao's 15-fight winning streak was snapped; he lost to Erik Morales in 2005.

• Arum on the decision: "I'm going to make a lot of money on the rematch, but this was outrageous."
