Citing an unspecified illness, Park In-bee has withdrawn from an upcoming LPGA Tour event, her management here said Wednesday.

IB Sports said Park recently complained of vomiting and fatigue and decided to skip the Safeway Classic, set to start Thursday in Portland, Oregon.

The agency added that Park will soon return to South Korea to rest.

The next event for the world’s No. 1 female golfer will be the Evian Championship, the fifth major of the season, from Sept. 12 to 15 in France. Park is the defending champion of this event, but it wasn’t among the LPGA majors in 2012.

Park won the first three majors of this season and has six victories overall in 2013. She hasn’t won since the U.S. Women’s Open in New York at the end of June. (Yonhap News)
