Roger Federer is a champion in his prime. The world's top-ranked player won the ATP tournament in Cincinatti, Ohio today over ninth-ranked James Blake of the USA. Federer next heads into the U.S. Open where he is the three-times defending champion. The competition is getting tougher all the time but Federer seems to rise to the occasion on tennis' biggest stages winning this year's Wimbledon and Australian Open titles.
