Kim has yet to win an event on the LPGA Tour but in 2009 she played the major championships well and is well placed to improve on that record even further in the first major of the LPGA Tour season.
21 year old Kim has already made a great start to her 4th season as an LPGA Tour with three top three starts in 2010, her bogey free round of 68 today confirming her current form.
Kim leads by one over Lorena Ochoa, Cristie Kerr and England's Karen Stupples with two time winner Karrie Webb and Stacey Lewis another shot back in a share of 5th.
First round leader Suzann Pettersen, after a round of 73, shares 7th position with Australian Women's Open Champion Yani Tseng.
Of the other Australians Katherine Hull is in 13th position at 1 under but it has been a disappointing week for Lindsey Wright and Wendy Doolan with both missing the cut.
