Creamer was scheduled to tee off at 9:10 a.m. in Thursdays opening round along with five-time Farr winner Se Ri Pak and In-Kyung Kim. But she notified tournament director Judd Silverman that she was pulling out of the tournament.
Creamer also withdrew from last weeks LPGA tournament in Pittsford, N.Y., because of the injury. She saw a doctor Monday in suburban Toledo and received a cortisone shot. Unable to play a practice round, she played in the pro-am Wednesday.
Creamer hopes to play in next weeks U.S. Womens Open at Saucon Valley Country Club in Bethlehem, Pa.
