Boxing's only eight-division world champion, Senator Manny "PacMan" Pacquiao dropped Keith "One Time" Thurman in round one and won a close split decision to earn a welterweight world title in the main event of a Premier Boxing Champions on FOX Sports Pay-Per-View event Saturday night from the MGM Grand Garden Arena in Las Vegas.

The sell-out crowd of 14,356 got treated to great action from the start, as an exciting first round was capped off by Pacquiao dropping Thurman for the first time in his career with a straight right hand late in the round.

In round 10, Pacquiao's landed a strong left hook to the body that clearly hurt Thurman and forced him to spend much of the remainder of the round backpedaling. The CompuBox scores were indicative of the close nature of the fight, with Thurman out landing Pacquiao 210 to 195, while Pacquiao was busier throwing 686 punches to 571 from Thurman.
