Novak Djokovic advanced to the third round of the Olympics on Tuesday by beating Andy Roddick 6-2, 6-1 at Wimbledon.
The second-ranked Serb had 34 winners on Centre Court at the All England Club. Roddick had 12.
Djokovic, a bronze medalist in the singles in 2008, raised his arms and smiled after the match. Roddick, a three-time Wimbledon finalist, quickly left the court with his head bowed.
