Australian rookie Grace Kim won the LOTTE Championship on Saturday at breezy Hoakalei Country Club for her first LPGA Tour title, beating Yu Liu and Yu Jin Sung with a birdie on the first hole of a playoff.

While Liu and Sung scrambled after hitting their second shots to the left of the green on the par-5 18th, the 22-year-old Kim went over the water to the right, then chipped to 8 feet to set up her birdie. Liu made a par and Sung had a bogey, hitting her third over the green and past Kim’s second.

“Kind of speechless right now,” Kim said. “I will let you know that my second shot on that playoff hole, that wasn’t intentional. I kind of got lucky there.”

“I think just the birdie on 17 was definitely the big momentum changer,” said Kim, who earned her LPGA Tour card last season with a fifth-place finish on the Epson Tour money list.

Sung finished with a 69, getting up and down from the front right bunker on 18 with a 9-footer. The 22-year-old South Korean played on a sponsor exemption after winning the LOTTE Open last year on the Korean LPGA.

Very good experience

“Very interesting and good experience for my golf life. Very good experience.” Sung said.

Liu began the round five strokes behind Sung in a tie for 15th, then shot a 64 — the best score in the two years at Hoakalei — to post at 12-under 276. The 27-year-old from China finished about an hour before the final group.

“It was a bit unexpected to be honest,” the former Duke player said. “I felt pretty over-achieved today.”

Linnea Strom, the Swede playing in the second-to-last group, missed a 10-foot birdie try on 18 to finish a stroke back with Peiyun Chien. Strom shot a 69, with a double bogey on the 14th. Chien, from Taiwan, closed with a 67.

Brooke Henderson, at No. 7 the highest-ranked player in the field, had a 71 to tie for 11th at 7 under. She’s the only multiple winner in event history, taking the 2018 and 2019 titles at Ko Olina.

The Chevron Championship, the first women’s major championship of the year, is next week in Texas.
