Klitschko wins by KO

Wladimir Klitschko stunned Calvin Brock with a sharp left, then finished him off with a thunderous right late in the seventh round Saturday in New York to successfully defend his IBF heavyweight title in a surprisingly competitive fight.

Klitschko rarely threw the right as he piled up points with his jab. But he found the range with the right midway in the bout, and Brock (29-1) had no chance when Klitschko (47-3) opened up the challenger’s defense with another quick left. The big right followed and Brock fell face-down.

He got up at eight, but was wobbly and referee Wayne Kelly stopped it at 2:10.

“I knew it was over there,” Klitschko said. “I should have tried that earlier, but it took me time to get my distance and rhythm. He was a good defensive fighter.”

Ali stops Burton

Laila Ali stopped a thoroughly outclassed Shelley Burton at 1:58 of the fourth round to defend her WBC women’s super middleweight championship in New York.

After throwing kisses to her father, boxing great Muhammad Ali, when she entered the ring, she made quick work of Burton.

“I wanted to knock her out cold,” Laila Ali said.
