Grand Slam record-holder Roger Federer earned another showdown with defending champion Novak Djokovic by outplaying Lukas Rosol 6-2, 6-2 to reach the semi-finals of the Dubai Open on Thursday. The mood of Federer's success against the Czech, who famously ousted Rafael Nadal at Wimbledon in 2012, was in sharp contrast with his desperate recovery from within sight of defeat against Radek Stepanek on Wednesday. I don't (usually) break somebody eight times and almost lose the match," Federer said, referring to his slide almost to 0-3 down in the final set against Stepanek.
