PORTLAND, Oregon (AP) Suzann Pettersen won the Safeway Classic for the second time in three years, taking advantage of playing partner Yani Tseng's final-round collapse Sunday 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. She also won the LPGA Lotte in Hawaii in April and won a Ladies European Tour event in March in China. She won the 2011 Safeway Classic at Pumpkin Ridge.
Tseng followed her third-round 63 with a 78 to slip to ninth place 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 closing with a 69, and 2008 champion Cristie Kerr was another stroke back after a 69.
