Federer admits ?loss of confidence

•?Roger Federer suspects he knows why he hasn’t been able to add to his record 16 Grand Slam titles the last two years.

The Swiss great last won a major championship at the 2010 Australian Open. He insists this has nothing to do with a declining game but “a bit of confidence not on my side and on my opponent’s side.”

“I’ve had some tough losses over the past couple of years,” Federer said, without referring to any specific matches.

Federer is ranked No. 3 and is joined in the field by No. 1 Novak Djokovic and No. 4 Andy Murray for the Dubai Championships, which start today.

•?Juan Martin del Potro beat Michael Llodra 6-4, 6-4 in the Open 13 final in Marseille, France, defeating yet another French player and winning his first title of the season.

•?Jurgen Melzer capped his amazing run through the Regions Morgan Keegan Championships in Memphis, Tenn., with a broken right big toe by beating Milos Raonic of Canada 7-5, 7-6 (4) for his fourth career title and first since 2010.
