RIO DE JANEIRO — Thailand’s Ariya Jutanugarn has withdrawn from the women’s Olympic golf tournament after 13 holes in Friday’s third round due to a left knee injury. “Very disappointed, because it’s Olympics, and I tell my caddie, I want to finish … four days,” Jutanugarn said. “I don’t care how many over I’m going to be, but I’m thinking about my career.”

Jutanugarn said she first felt the injury late in Thursday’s second round, but it didn’t hurt until after she was practicing post-round.

“After the round, I started feeling pain,” she said. “I feel a little bit tight, like second round, like almost last three holes, but I finish okay. After that, I rest and I start to hit the ball after I play yesterday, and then I hurt, so I stop.

“I went to putt and I can’t bend … down, like a sharp pain just happened.”

Thursday night, after receiving medical treatment at the Olympic village, the pain went away, Jutanugarn said. But it returned Friday morning.

The first-round leader with a 65, world No. 2 Jutanugarn was clearly struggling Friday, having shot 41 on the first nine and making a triple-bogey 7 at the 13th. She was 12 over through 13 holes for the day before exiting.

Jutanugarn has won four times this year on the LPGA Tour, including the Women’s British Open, making her the first Thai golfer to win a major.
