CHICAGO, United States — South Korea’s Park Sung-hyun birdied twice in a weather-disrupted playoff Sunday to win the Women’s PGA Championship, capturing the second major women’s golf title of her career.

The 24-year-old from Seoul, last year’s US Women’s Open champion, defeated compatriot Ryu So-yeon, denying her bid to reclaim the world number one ranking, and Japanese teen star Nasa Hataoka in the playoff to capture the $547,500 top prize.

“It was a really long round today and I still can’t believe I’m sitting next to this trophy,” Park said.

Hataoka and the South Koreans each finished 72 holes at Kemper Lakes deadlocked at 10-under par 278.

Fifth-ranked Ryu and sixth-ranked Park each birdied the first playoff hole, the par-4 18th, while Nataoka was eliminated with a par.

The Koreans, who shared LPGA Player of the Year honors in 2017, reached the green at the par-4 16th, the second playoff role, when play was suspended for dangerous weather in the area, halting the drama at its peak for 20 minutes as the tension mounted.

When play resumed, Ryu missed her birdie putt and Park sank hers for the victory then broke into tears.

“I got less nervous during the playoff. I was even joking,” Park said.

“I was a little worried, but even though it was a tough week, I feel like I played really well. All the hard work paid off and that’s what made me cry.”

Park, last year’s LPGA Rookie of the Year, won her second title of the year after the LPGA Texas Classic in May. It was her fourth LPGA title overall after last year’s US and Canadian Women’s Open crowns.
