LOS ANGELES, Calif. (AP) Juan Martin del Potro has been asked the same questions about his right wrist and his hip injury so often, he says his answers have begun to sound recorded.

The 2009 U.S. Open champion missed most of last year because of wrist problems and understands why people are curious. He said he would much rather talk about his tennis.

Del Potro is the No. 2 seed in this week's Farmers Classic at the Los Angeles Tennis center on the UCLA campus, where he won his first hardcourt title in 2008. The 6-foot-6 Argentine has won 35 of his 44 matches and two championships this year and is No. 19 in the rankings after slipping to No. 485 on Jan. 31. He had been No. 4 before being sidelined.

Del Potro will play his opening match Wednesday night.
