SAN ANTONIO - Jimmy Walker won his hometown Texas Open on Sunday to become the first two-time winner this season on the PGA Tour, beating fellow Texan Jordan Spieth by 4 strokes.

Walker closed with a 2-under 70 to finish at 11-under 277 at TPC San Antonio. He won the Sony Open in Hawaii by 9 shots in January.

Spieth also finished with a 70. Walker and Spieth will move to career highs in the world ranking, with Spieth going from sixth to fourth and Walker from 13th to 10th.

Phil Mickelson, looking for some momentum heading to the Masters, closed with a 76 to drop into a tie for 30th at 4 over.

Marc Warren and Harris English failed to crack the top 50 in the world ranking, which would have given them spots in the Masters.

LPGA Tour

CARLSBAD, Calif. - Cristie Kerr closed with a 7-under 65 and won the Kia Classic for her first LPGA Tour title in nearly two years.

Kerr made four straight birdies on the back nine at Aviara to pull away from Mirim Lee and 17-year-old Lydia Ko. It was her 17th career win, and her first since May 2013 at the Kingsmill Championship.

Kerr finished at 20-under 268 to break the tournament record by 6 shots.

Champions Tour

SAUCIER, Miss. - David Frost survived a 1-stroke penalty on the par-3 17th hole to win the Mississippi Gulf Resort Classic for his sixth Champions Tour title. He finished with a 4-under 68 at Fallen Oak for a 1-stroke victory over Tom Lehman and Kevin Sutherland.

Frost was penalized after his coin marking his ball on the green moved when he accidentally dropped the ball on it.
