PARIS(AP) Former No. 1 Marat Safin's career is over after a 6-4, 5-7, 6-4 loss to Juan Martin del Potro in the second round of the Paris Masters.

The 29-year-old Safin, a two-time Grand Slam title winner, put on a solid performance on center court Wednesday but was unable to overcome the U.S. Open champion.

Safin, a three-time winner in Paris, captured the 2000 U.S. Open and 2005 Australian Open among 15 singles titles. He has said he'll quit after this season.

The charismatic Russian hasn't won a title since the victory in Australia four years ago. His best result this year was reaching the semifinals at St. Petersburg last month.
