FORT WORTH, Texas (AP) ― Charlie Wi took advantage of playing partner David Tom’s third-round collapse Saturday to take a one-stroke lead into the final round of the Colonial.

Wi, seven strokes behind Toms at the start of the round, shot a 4-under 66 to reach 13 under. After opening with bogey-free 62s to tie the PGA Tour record for the first 36 holes, Toms had a 74 to fall to second.

Wi took the lead with a 32-foot birdie putt on the par-3 16th hole soon after a weather delay. After Wi holed the putt, Toms’ 16-foot par chance just missed for a two-stroke swing.

The 44-year-old Toms, coming off a playoff loss last week in The Players Championship, opened with a birdie, but had three bogeys in a five-hole stretch. Worse was a three-putt from 7 1/2 feet for double bogey at No. 14, where Wi chipped to 12 feet to save par right before a 1-hour, 20-minute delay.

John Senden was 9 under after a 70.

Sybase Match Play Championship

Angela Stanford birdied four of the final five holes to beat Paula Creamer 2-up and set up an all-America semifinal with Cristie Kerr in the Sybase Match Play Championship.

Top-seeded Choi Na-yeon of South Korea will face No. 3 Suzann Pettersen of Norway in the other semifinal Sunday morning at Hamilton Farm Golf Club.

The championship in the $1.5 million tournament will be decided Sunday afternoon, with Stanford looking to reach the final for the second straight year. She lost to Yoo Sun-young last year.

Kerr, the No. 3 seed who hasn’t played more than 16 holes in any match, beat Ai Miyazato 3 and 2. Choi beat Sophie Gustafson 2-up, and Pettersen holed an 8-foot birdie putt on No. 18 to edge top-ranked Yani Tseng 1-up.

In the third round in the morning, Gustafson beat Michelle Wie 1-up.

World Match Play Championship

Luke Donald will meet Martin Kaymer in the World Match Play Championship semifinals Sunday, with the No. 1 spot firmly in their sights after top-ranked Lee Westwood’s loss.

Westwood’s 1-up loss to Ryder Cup teammate Ian Poulter in the round of 16, left Westwood vulnerable at the top of the rankings ― and his closest pursuers took advantage at Finca Cortesin.

The second-ranked Donald beat Johan Edfors in 19 holes, then edged Masters champion Charl Schwartzel 2-up in the quarterfinals. No. 3 Kaymer beat Soren Kjeldsen 3 and 2, and Alvaro Quiros 2-up.

Donald or Kaymer will take the No. 1 spot with a tournament victory. They met in the final of the World Golf Championships-Match Play Championship in Arizona in February, with Donald winning 3 and 2.
