Lorena Ochoa will be aiming to defend her title when the Safeway Classic starts on Friday at Columbia Edgewater Country Club.
Ochoa, whose last win came in May at the Sybase Classic, clinched last year's title by five strokes after finishing at 12 under par.
Katherine Hull, last week's Canadian Open champion, will also feature in the tournament, and she said: "I'm still on cloud nine. I feel pretty good about my game and I'm hoping to have another good finish this week."
