The third-ranked Creamer, coming off a third-place finish last week in Thailand, matched Park at 6-under 138 on the Tanah Merah Country Clubs Garden Course.
I feel very confident with where Im at, Creamer said. I feel like Ive gained something today. The gap yesterday, there were people there, now theres not quite as many, but there are still 3-, 4-, 5-under. But I like being in the lead. Ill take the lead over any place for the day.
Creamer has eight LPGA Tour victories, four last season. Park, the former UCLA star who won the 2004 U.S. Womens Amateur, is seeking her first LPGA Tour victory.
I just want to take it one shot at a time, and thats exactly what I did, Park said. I had a great time out there.
Katherine Hull, the Australian Ladies Masters winner last month, shot a 69 to join Mi Hyun Kim (68) at 5 under. Sun Young Yoo (69) and Ai Miyazato (72) were 4 under, and Angela Stanford (72) was another stroke back along with Lindsey Wright (69), Shanshan Feng (71) and Se Ri Pak (72). Stanford won the season-opening SBS Open.
Top-ranked Lorena Ochoa, the defending champion coming off her 25th LPGA Tour victory last week in Thailand, was 2 under after a 73. Fourth-ranked Suzann Pettersen (70) and Hall of Famer Juli Inkster (70) also were 2 under.
