Manny Pacquiao’s speed and power were way too much for Miguel Cotto’s heart.

Pacquiao put on yet another dominating performance Saturday night, knocking down Cotto twice and turning his face into a bloody mess before finally stopping him at 55 seconds of the 12th round.

The Filipino star used his blazing speed and power from both hands to win his seventh title in seven weight classes and cement his stature as the best pound-for-pound fighter in the world. Cotto took such a beating that his face was a river of red from the fury of Pacquiao’s punches, but he refused to quit even as his corner tried to throw in the towel after the 11th round.

“I didn’t know from where the punches were coming,” Cotto said.

The fight was billed as a 145-pound classic, and in the early rounds it didn’t disappoint. The two went after each other with a vengeance and Cotto more than held his own as they traded punches in the center of the ring before a roaring sellout crowd at the MGM Grand arena in Las Vegas.

“Our plan was not to hurry, but to take our time,” Pacquiao said. “It was a hard fight tonight and I needed time to test his power.”
