LONDON (AP) Stan Wawrinka received a much-needed confidence boost with a 6-1, 6-1 victory over Tomas Berdych on Monday in his opening round-robin match at the ATP Finals.
Serving and returning impeccably, the Australian Open champion outclassed his Czech opponent with a range of backhand and volley winners.
Wawrinka traveled to London with his form in question after winning only two matches since his quarterfinal exit at the U.S. Open. But he got off to a strong start against Berdych, winning five consecutive games to take the first set.
Berdych, who had 20 unforced errors, fought harder at the start of the second set but dropped his serve after a tight third game and never recovered.
