Creamer, who was at the top of her game helping the Americans win the Solheim Cup last week, was scheduled to go off at 9:16 a.m. local time with Suzann Pettersen and Jiyai Shin.
Juli Inkster, the all-time American points leader in Solheim Cup history, called Creamer the true leader among players on last weeks victorious team.
Though Creamer played the Safeway Classic pro-am Wednesday at Pumpkin Ridge Golf Clubs Ghost Creek Course, she did so feeling ill.
Last week was awesome, but Im very sick from last week, Creamer said before teeing it up in the pro-am. My bodys shutting down.
I was getting much better over time. The last couple of months have been my best, physically, health wise. I think a lot of it is just being run down and my body is very tired.
According to her family, Creamers condition worsened after the pro-am. She was too ill to return to the course Thursday and never left her room. Shes being treated by Portland physicians with the long-distance assistance of Dr. William Ruderman, an Orlando gastroenterologist recommended to the family by Arnold Palmers medical team.
Creamer was first stricken with the mysterious ailment at the season-ending ADT Championship in November. She was hospitalized the night before the final round and treated for peritonitis but returned to finish. She withdrew from the J Golf Phoenix event in late March with stomach problems and arrived for the Kraft Nabisco Championship reporting she had lost seven pounds while unable to keep food down in Phoenix.
It was after the Kraft Nabisco that Creamer first met with Ruderman, who put her through a battery of tests that included X-rays, MRIs and biopsies through her digestive tract. The medical staff ruled out Crohns disease, Celiac disease, tumors and other possible causes. She was treated with antibiotics and the malady eventually faded through the summer without a definitive diagnosis of what caused it.
Creamer is scheduled to play in the CN Canadian Womens Open next week. She plans to remain under treatment in Portland for the weekend, according to her family, but if her health doesnt improve, she may return to Orlando Sunday to seek medical treatment.
