She and defending champion Mi Hyun Kim will lead the 144-player field through the 72-hole event in which the winner will receive $270,000 of the $1.8 million purse'a $400,000 and 18-hole increase over 2007.
Fresh off a week of rest at home in Mexico, Ochoa has an opportunity to tie the LPGA record for most consecutive wins in tournaments participated held by Nancy Lopez (1978) and Annika Sorenstam (2004-05). Ochoa won four consecutive and five of six tournaments she played in before sitting out last week's Stanford International Pro-Am, won by Sorenstam'her second victory of the year.
Kim's attempt at a title defense will be made more challenging by Ochoa's presence as well as last week's runner-up and five-time Tour winner Paula Creamer, as they return to the 6,602-yar, par-71 Cedar Ridge Country Club track.
Ochoa, especially, has finished no worse than a tie for fifth in three career starts (third, 2005; T3, 2006; T5, 2007). Last year, Kim defeated LPGA and World Golf Halls of Fame member Juli Inkster in a one-hole, sudden-death playoff to earn her eighth-career victory and pocket $210,000. Kim donated $100,000 of her winner's check to the United Way Greensburg Disaster Relief Fund to aid tornado victims in Kansas following her victory.
Native Oklahoman Stacy Prammanasudh returns to Tulsa with two top-10s and more than $160,000 to her name this season after finishing tied for 22nd at last year's tournament.

Last year, she earned a spot on the 2007 U.S. Solheim Cup Team and earned two of the team's 16 points en route to a victory over the European Team.
Reigning U.S. Women's Open champion Cristie Kerr is also slated to revisit Cedar Ridge CC and the course where she fired a career-low 10-under-par 61 on the way to her ninth LPGA career victory in 2006.
