Roger Federer may be a little sleep deprived.

After a brief paternity leave to be with his twins born last week, Federer lost to the 47th-ranked Jeremy Chardy of France, 1-6, 6-3, 7-6 (8-6), Wednesday at the Italian Open.

The world No. 4 Swiss had match point in the tiebreaker but Chardy, who hadn’t beaten a top-10 player since last year’s Australian Open, saved it with a cross-court forehand winner.

“That passing shot is a tough one for me to take, because he’s not going to make that very often,” Federer said (via Associated Press). “But it happens and credit to him to fight his way back into the match and get it.”

Federer arrived on Monday after withdrawing from the Madrid Open but got permission from his team to enter the Italian Open, where he had a first-round bye.

“I mean, I’d rather be home, no doubt about that, and I’d rather spend time with Mirka and the kids now,” Federer told The Daily Telegraph on Tuesday. “But it’s a quick trip this one, and after that we hope that we can all make it together to Paris. I’m looking forward to coming back in a few days already.

The stay was probably shorter than he would have wanted.

On the women’s side, Venus Williams struggled against 14th-ranked Carla Suarez Navarro of Spain, losing, 6-4, 6-2. Williams has not won a tournament since her Dubai title in February.

Top seed and younger sister Serena fared much better and had no trouble dispatching Germany’s Andrea Petkovic, 6-2, 6-2.

Christina McHale and Varvara Lepchenko are the only other Americans to reach the third round.
