Federer returns to action after the birth of his twin daughters

Roger Federer preparing for the Rogers Cup

Roger Federer returns to tennis after long absence today at the Montreal Masters with top seed Federer playing just three weeks after the birth of his twin daughters.

The Swiss is happily on a roll after winning the French Open for the first time and Wimbledon for the sixth.

Federer can't predict the outcome at the first major event since Wimbledon ended five weeks ago, when he moved deeper into the record books with his 15th Grand Slam title, earned at the expense of Andy Roddick.
