Switzerland's top seed Roger Federer (left) is congratulated by Fabrice Santoro of France after winning his second round match.
The 35-year-old Santoro, playing in a record 62nd Grand Slam singles tournament, had no answers to Federer's mastery as he lost 6-1, 6-2, 6-0.
"Everything looks easy to him," the Frenchman smiled. "There is no space to play. There is no space to hit aces because he's returning everything.
"I'd love to play him once again. Because it's so beautiful, what he's doing," Santoro added.
