Zou Shiming defeated Prasitsak Phaprom by a near-shutout decision to win the vacant WBO flyweight title on the Jessie Vargas-Manny Pacquiao undercard Saturday in Las Vegas.

The two-time Olympic champion outclassed Phaprom in their first meeting, a unanimous-decision victory in November 2014 in China. It was more of the same at Thomas & Mack, although the fight was a lot cleaner this time.

Shiming (9-1, 2 knockouts) attacked Phaprom (39-2-2, 24 KOs) with precision from the opening bell, consistently landing quick, effective combinations while using his legs to avoid most of his Thai opponent’s punches.

Phaprom never stopped trying but didn’t have the skills to compete against the new titleholder, whose only obvious weakness is a lack of punching power. The loser suffered a knockdown in the second round when his gloves touched the canvas after he took a hard right.

The official judges scored it 120-107, 120-107 and 119-108, meaning Phaprom won only one round on one card. THE RING scored it 120-107 for Shiming.

Shiming landed three times as many punches as Phaprom, according to punch stats: Shiming landed 347 of 778 total shots, Phaprom 107 of 503.

Shiming, 35, lost a decision to Amnat Ruenroeng in his only other title fight, in March of last year.
