LAS VEGAS — The old Manny Pacquiao returned for thrilling bursts, hounding Timothy Bradley onto the ropes and battering the welterweight champion with whip-quick combinations that recalled the Pacman’s magical prime.

Although he tried mightily, Pacquiao (56-5-2) didn’t stop or even really hurt Bradley during 12 mostly exciting rounds Saturday night, settling for the lucrative revenge of a unanimous-decision victory.
