ZURICH (AP) — Roger Federer has posted the first public photo of his twin girls on the Internet.

Federer wrote below the photo on his Facebook account on Friday, thanking friends and fans for their warm wishes. He said: "The girls and mom are doing great."

Tennis' top-ranked player and his wife, Mirka, are each holding one of the babies in the picture. Federer said it was taken by his father.

Charlene Riva and Myla Rose were born July 23 on what Federer said was the best day of his life.

The Swiss player is not scheduled to return to the ATP Tour until Aug. 10 in Montreal. Last month, he won an epic Wimbledon final against Andy Roddick for his 15th Grand Slam title, breaking Pete Sampras' record.
