ZURICH — Roger Federer is showing off his new doubles team.

The Swiss tennis great has posted the first public photo of his twin girls on the Internet. Federer wrote below the photo on his Facebook account Friday that the girls and mother are "doing great." He thanked friends and fans for their wishes.

Federer and his wife, Mirka, are each holding a baby in the picture. Federer said the photo was taken by his father. Charlene Riva and Myla Rose were born July 23 on what Federer called the best day of his life.

The top-ranked Federer is not scheduled to return to the tour until Aug. 10 in Montreal. Last month, he beat Andy Roddick in the Wimbledon final for his 15th Grand Slam title, breaking Pete Sampras' record.
