Steinhauer will be in the field to defend her title, but winning it again will take some reversal of recent history. The $1.7 million tournament hasn't seen a repeat winner since Beth Daniel in 1989-90.
Recent champions have included Annika Sorenstam in 2006 and Cristie Kerr in 2004, but neither player is scheduled to play this week. World No. 1 Lorena Ochoa and Paula Creamer, winner of last week's Jamie Farr Owens Corning Classic, are also skipping the event, while Michelle Wie will make her fourth start in four events.
Next week's event is the lucrative Evian Masters, where Natalie Gulbis finally claimed her first LPGA Tour win last season.
