PORTLAND, Oregon (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 is winless in 37 events since the Kia Classic in March 2012.
