Roger Federer of Switzerland Beat His Spanish Opponent Fernando Verdasco At Round-robin Stage of ATP World Tour Finals in London

Roger Federer of Switzerland overcame an erratic forehand and Fernando Verdasco on Sunday, rallying to beat his Spanish opponent 4-6, 7-5, 6-1 in the round-robin stage of the ATP World Tour Finals in London.

The top-ranked Federer was broken once — in the opening game of the Group A match after double-faulting on the first point — but he never looked dominating until late in the second set when he converted his first break point to even the score at one set apiece.

Coming into the tournament for the top eight players in the world, Federer was riding a two-match losing streak.

In another Group A match, Andy Murray of Scotland beat Juan Martin del Potro of Argentina 6-3, 3-6, 6-2.

Del Potro needed a medical timeout after the third game in the first set to treat a bleeding nose. He shrugged off the incident after the match, saying he has a history of nosebleeds.

"I have a big nose, that's the problem," he said. "It's just bleeding. I don't know why."
