TORONTO — Top-ranked Roger Federer was knocked out of the Rogers Cup with a 2-6, 7-5, 6-4 loss to France's Gilles Simon Wednesday in a second-round tennis match.

Federer, who won the tournament in 2004 and '06, was playing his first match since losing the Wimbledon final in five sets to Spain's Rafael Nadal.

Second-seeded Nadal didn't look stellar in his first match either, struggling early on before ousting Canadian qualifier Jesse Levine 6-4, 6-2.
