"I can't remember the last time I did that in a tournament, so it was a bit unsettling," Watney said about his shank. "The big picture? I'm tied for the lead, and I would have taken that on Thursday morning."
Instead of pulling away from the pack, their mistakes in a wild final hour allowed a dozen players to get within three shots of the lead.
One of them was Rory McIlroy, who shot 73 and missed seven putts from the 5-foot range or closer, which was no way to celebrate his 24th birthday. McIlroy ranked 82nd out of the 83 players who made the 36-hole cut in the key putting statistic, yet he still goes into the final round with a good chance for his first win of the year.
Two-time champion Cristie Kerr shot a 5-under 66 on Saturday to take a two-stroke lead over second-ranked Stacy Lewis and Suzann Pettersen after the third round of the LPGA Tour's Kingsmill Championship in Williamsburg, Va.
Kerr, the only two-time winner at the River Course, made six birdies to reach 10-under 203. She took command on a day when seven players shared the lead at one point or another, then faltered.
Lewis shot a 69, and Pettersen, the 2007 champion, had a 68.
Gene Sauers chipped in for birdie on the par-4 17th a day after making a double bogey on the hole, and finished with a 6-under 66 on Saturday to take a two-stroke lead in the Champions Tour's Insperity Championship.
Sauers hit into the water on the 17th hole Friday, but atoned for the mistake Saturday with a 25-yard chip. He had an 8-under 136 total at The Woodlands Country Club in Texas.
