Suzann Pettersen posted four rounds under par, including a five-under 67 in the final round, to walk off with her first major championship title last year.
The title came two months after Pettersen collapsed in the final round of the season's first major, the Kraft Nabisco Championship. There, Pettersen coughed up four shots in a three-hole span from the 17th to cede the title to another first-time major champion, Morgan Pressel.
Pettersen atoned for that collapse at Bulle Rock. She ran home four birdies on the back nine to fend off Karrie Webb, the 2001 champion. Webb finished second for the second year in a row.
When Webb won in '01, that made her youngest player to complete the career Grand Slam. She was just 26 at the time.
Women's world No. 1 Lorena Ochoa is expected to play this week after missing last week's event to be with her ailing uncle, who later passed away.
Ochoa has won the last two majors, the Kraft earlier this year and the Women's British Open last year. Those were her first two major titles.
Annika Sorenstam won this event three straight years from 2003-2005. Only Mickey Wright has won this title more than Sorenstam.
Two-time winner Juli Inkster will snap her run of 56 straight majors played to attend the graduation of her youngest daughter. Inkster last missed a major when she gave birth to that same daughter.
After 11 years at DuPont Country Club, this is the fourth straight year at Bulle Rock.
The GOLF CHANNEL will have three hours of coverage all four days.
The LPGA Tour returns to action in two weeks with the Wegmans LPGA, where Ochoa is the defending champion.
