Filipino ring icon Manny Pacquiao comprehensively dismantled American Chris Algieri to retain his WBO welterweight title at the Cotai Arena in Macau on Sunday. Pacquiao dropped Algieri to the canvas six times during the 12-round contest in the southern Chinese city to win an overwhelming unanimous decision: 119-103, 119-103, 120-102 on the judges' cards.

Algieri, the unbeaten WBO light welterweight champion, was outclassed from the start, with the eight-division world champion Pacquiao knocking the Long Islander down twice in the second round, though on one occasion it looked like a slip. Pacquiao was landing punches at will as the quick Algieri tried to run, slip and hide from the onslaught.

But the congressman form Sarangani province really turned it on from the sixth, smashing Algieri to the canvas with a devastating straight left. The American only just beat the count and dropped to his knee a moments later as blows rained in from all angles. He somehow survived and was knocked down twice more in the ninth and 10th, with one left sending him sprawling across the ring.

"He's perfected his style," said Algieri. "He's perfected the art of fighting like Manny Pacquiao. He hurt me once when he buzzed me with a left hook. But that was the only time. Two of the knockdowns were slips.”
