London, Jul 26 (IANS): Andy Roddick of the United States is eagerly awaiting the London 2012 Olympic Games tennis tournament which will be played at Wimbledon on grass, one of his favourite surfaces.

It's the first time since tennis was reintroduced to the Games as a medal sport (at Seoul 1988) that it will be played on grass. Roddick reached the men's singles final at the Wimbledon Championships three times during his career - in 2004, 2005 and 2009, reports Xinhua.

"I'm excited the Olympics are on grass as it's a surface that I favour," he said. "I've been looking forward to it."

"I'm curious to see what it will feel like. It's two-out-of-three sets until the final. Two-out-of-three sets on grass is a crapshoot, so I'm excited. Anything goes there."

Roddick, who last competed in the Games at Athens 2004, added: "You are playing for something different. Normally we deal in very selfish terms as a tennis player, especially as a singles player. It's a little bit different when you are playing for the United States and you're trying to get a medal for it. I certainly take that responsibility seriously."
