Fred Couples shot a 3-under 68 on Saturday to take a one-stroke lead after the third round of the Senior Players Championship, the Champions Tour's final major of the season.

Couples is at 11 under for the tournament and is trying for his first Champions Tour title since a seven-stroke victory last October at the Adminstaff Small Business Classic in Texas. Since his fourth victory on the senior tour, Couples has struggled with his back, but the injury has healed following a non-traditional procedure in Germany six weeks ago.

Peter Senior remained in second at 10 under after a third-round 68 and is tied with John Cook, who moved up from fourth with a 66. Corey Pavin is fourth at 8 under after shooting a 69.
