Hee-Won Han was a runaway winner last year as three rounds in the 60s gave her a five-stroke win over Diana D'Alessio. Han will have her hands full this week trying to repeat as champion.
A strong field this week includes five of the top 10 players in the world. World No. 3 Annika Sorenstam will make her first appearance at this event, while last week's winner, Suzann Pettersen, will look to improve upon her tie for 38th from last year.
Last year this was a three-round event, but it is scheduled for four rounds this time around.
There is no television coverage this week. The LPGA wraps up its three-week run in the Far East next week with the Mizuno Classic. Karrie Webb won last year by four strokes, ending Annika Sorenstam's run of five straight wins at that event.
