(AP) Suzann Pettersen won the Safeway Classic for the second time in three years Sunday, taking advantage of playing partner Yani Tseng's final-round collapse at Columbia Edgewater.
Three strokes behind leader Tseng entering the round, the third-ranked Pettersen closed with a 5-under 67 for a two-stroke victory over second-ranked Stacy Lewis.
Pettersen finished at 20-under 268 for her 12th LPGA Tour victory. The 32-year-old Norwegian also won the LPGA Lotte in Hawaii in April and won a Ladies European Tour event in March in China. She won the 2011 tournament at Pumpkin Ridge.
Tseng followed her third-round 63 with a 78 to tie for ninth at 12 under. The Taiwanese star, a 15-time winner on the tour who had a 109-week run at No. 1 in the world ranking, is winless in 37 events since the Kia Classic in March 2012.
Lewis, a three-time winner this year, shot a 68. Lizette Salas was third at 17 under after a 69, and 2008 champion Cristie Kerr was another stroke back after a 69.
A 72-hole event for the time, the tournament returned to Columbia Edgewater after four years at Pumpkin Ridge. Columbia Edgewater also was the tournament site from 1990-2008.
After a double bogey on the par-3 second hole, Pettersen birdied five of the next six holes and eight of 11. The European Solheim Cup player made an 18-foot birdie putt at the par-3 eighth to overtake Lewis for the lead, curled in a 5-footer for birdie on the par-5 10th and made a 25-footer from off the green on the par-4 11th.
Pettersen opened up a four-stroke lead with an 8-foot birdie putt on the par-3 13th. She ran into trouble at the 175-yard, par-3 16th, following a short tee shot with a poor chip. But she minimized the damage when her next chip rolled within 3 feet to set up a bogey-saving putt. She then closed with two pars.
