Roger Federer of Switzerland defeats his opponent Julien Benneteau of France in singles Monday in straight sets in less than an hour.
The world No.1 swept his 32-ranked opponent 6-2, 6-2 of the Olympic second round and will now play either Luxembourg's Gilles Muller or Uzbekistan's Denis Istomin.
Federer, who has 17 Grand Slams titles, took four times the service of the French without conceding a single break point. He showed off his class with 24 strokes winners, seven aces and only seven unforced errors.
Routine wins have been elusive at the Olympics for Federer, who is playing in the games for the fourth time and still seeking his first singles medal. He was pushed to three sets in the opening round but he easily eliminated Benneteau, who held a two-set lead against Federer at Wimbledon a month ago before losing.
In the rematch, Federer lost only 13 points in his eight service games. He had 24 winners and only seven unforced errors.
Elsewhere in the draw, world No. 2 Novak Djokovic will meet former U.S. Open champion Andy Roddick in the second round of the Olympic tennis tournament after the American beat Slovakia's Martin Klizan on Monday.
Roddick forced his way past Klizan 7-5, 6-4 thanks to late breaks in both sets as the Slovak, ranked 52nd in the world, put up stiff resistance.
"It was good. I got myself a couple of great points and only a couple of breaks, but I served pretty well and got through," Roddick said.
The Olympic tennis is being played at Wimbledon, where Djokovic won last year and Roddick has reached the final three times, most recently in 2009.
