LONDON (Reuters) - Roger Federer moved a step closer to an elusive Olympic singles gold after reaching the final eight but Israel's Jonathan Erlich and Andy Ram ended the world number one's hopes of repeating his Beijing doubles success.
Venus Williams' hopes of becoming the first tennis player to win four Olympic gold medals will have to rest on the doubles after she was knocked out of the women's singles in a 7-6 7-6 third-round defeat to Germany's Angelique Kerber.
