World No. 1 Inbee Park withdrew from the Safeway Classic on Tuesday, citing an illness.
"I'm disappointed I will be unable to play this week in Portland due to an illness," Park said via the LPGA Tour's twitter feed. "Safeway is such a great supporter of our Tour and I always look forward to playing in front of the great crowds in Oregon."
Park has won six times this year and is just one of three players with multiple victories. Stacy Lewis and Beatriz Recari are the other two players with multiple titles this season.
The 25-year-old South Korean hasn't finished inside the top 10 after winning three straight events, including her second and third major championships of the year.
Park hopes to be able to play in two weeks, when the tour has its' fifth and final major, the Evian Championship.
