Newly crowned U.S. Women's Open champion Cristie Kerr heads the field, which will tee it up at Highland Meadows Golf Club for the 19th straight year.
Last year, Mi Hyun Kim birdied the third playoff hole to knock off hard-luck loser Natalie Gulbis. Both Kim and Gulbis closed with rounds of 6-under 65, but Kim had been as many as four behind, before closing with three birdies on the back nine to force the extra session.
Gulbis and Kim began the final round tied for the lead, but needed everyone of those 65 strokes to stay ahead of the rest of the field. Paula Creamer matched their 65s to end one back at minus-17, with Se Ri Pak two back after a 66.
Pak will look to continue her amazing play at this event, where she has posted four wins and eight top-10s in the previous nine years. If she wins for a fifth time, she would join Mickey Wright and Annika Sorenstam as the only players to win the same LPGA event five times.
Next week, the LPGA shifts back to New York for the HSBC Women's World Match Play Championship, where 39th-seeded Brittany Lincicome defeated eight-seed Juli Inkster for the crown last year.
