New York, Oct 13 Tennis star Andy Roddick proved he's a champion after he won 150 dollars bet with Virgin heir Sam Branson - to play with his left hand.

The former No. 1 was vacationing on Richard Branson's Necker Island when Sam challenged him to a set with a condition that right-handed Roddick had to play as a leftie.

"Even with the handicap, the result was a convincing victory for Roddick. He thrashed Branson 6-0," the New York Post quoted a source as saying.

Roddick's wife Brooklyn Decker had recently revealed that her husband "stalked" her.

The 22-year-old fashion model caught Roddick's attention when he saw her in the Sports Illustrated Swimsuit Edition.

"He was the first to admit that he kind of stalked me," she said.

"But his line was, 'It's only stalking if the other person doesn't like it'," she added. (ANI)
