After three weeks off to treat back pain and his early elimination in the tournament in Gstaad, Roger Federer was on the court for his debut in Cincinnati. The world No. 5 has obtruded on the German Phillip Kohlschreiber (26th in the ATP) in two sets, 6/3, 7/6 [9-7].

The Swiss defending champion will face in the eighth the winner of the match between Tommy Haas, who defeated Kevin Anderson and Marcel Granollers.
