"Life goes on,'' Bradley said of his first pro defeat. ``It's back to the gym. Not a big deal.''
Judge Glen Trowbridge scored the bout 118-110 for Pacquiao, while Michael Pernick and Canada's Craig Metcalf saw it 116-112 for the ``Pacman'', whose every move was cheered by the star-studded crowd of 15,601.
After a tight first round, Pacquiao made his power felt in the second.
The third saw both fighters exchange at a furious rate, Pacquiao again landing the more damaging blows.
But Bradley shook Pacquiao in the fourth, and Pacquiao said California's ``Desert Storm'' was an improved fighter from the one who took a bitterly debated split decision in their first fight.
Although the pace slowed in the later rounds, Pacquiao put together multi-punch combinations in the seventh and out-worked Bradley in the remaining rounds.
After throwing few punches in the 11th, a desperate Bradley swung wildly in the 12th, and Pacquiao finished the fight with a cut over his left eye from a clash of heads late in the final round.
