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.
