SAN ANTONIO, Texas — Phil Mickelson withdrew from the Texas Open after pulling a muscle in his right side teeing off on his 10th hole in Saturday's third round.
"I pulled a muscle on my downswing trying to hit it hard," Mickelson said in a statement. "It just killed and it wouldn't subside for 10 or 12 seconds. I'm going back to San Diego (for) a couple of days and have a doctor look at it, but there's really not much you can do for a pulled muscle. I hope I'll be okay to play the Shell in Houston, but I just don't know."
Mickelson is entered in the Houston Open this week, the last event before the Masters.
He was 1 over in the round and 4 over overall when he was taken off the course in a cart. On Friday, Mickelson made the cut on the number, shooting 70 after an opening-round 77.
It's the second time this year Mickelson has withdrawn in the middle of a tournament. He pulled out at Torrey Pines after making the cut because of a back injury.
Steven Bowditch, a 30-year-old Australian seeking his first PGA Tour title, shot 4-under 68 to reach 12-under 204 and open a three-shot lead. Matt Kuchar and Andrew Loupe were tied for second. Kuchar shot 65, and Loupe had 70.
"I've won four or five times between Australia and Web.com (tours)," said Bowditch, who would get into the Masters with a victory. "I've got a little experience but not a great deal, especially at this level. I've never slept on a lead, so we'll see how we go."
Bowditch, ranked 339th in the world, chipped in at the first two holes, for birdie at No. 1 and eagle at the par-5 second. He drove to chipping distance at the 338-yard fifth hole and made a 4-foot birdie putt.
LPGA: Cristie Kerr made a 55-foot par-saving putt after hitting her final approach into the water, giving her a share of the lead with Lizette Salas after the third round of the Kia Classic in Carlsbad, Calif. Kerr finished with 2-under 70 to match Salas (69) at 10-under 206. Kerr holed out from the edge of the green on the par-4 18th after taking a penalty drop. Dori Carter, the second-round leader after a course-record 64, had 74 to drop into a tie for third at 8 under with Anna Nordqvist (67), Ayako Uehara (67) and Shanshan Feng (69).
