Creamer shot a 5-under 67 in the second round, while Sorenstam had a 71 and Korean Kim a 69 as the three stood at 6-under 138.
"I thought I played quite well today," said Sorenstam, who won this event last year for her first of 10 titles in 2005. "I got off to a really good start. I'm a little disappointed in the end when it was getting so dark. I couldn't really read the greens for the last few holes."
