PATTAYA, Thailand -- Angel Yin shot a blemish-free final round to win the LPGA Thailand tournament by a stroke from a fast-finishing Akie Iwai of Japan and claim her second tour title on Sunday.
The 26-year-old American made seven birdies -- and no bogeys -- for a four-round total of 28-under 260 at Siam Country Club's Pattaya Old Course, which was enough to hold off Iwai despite her 61 being the lowest score of the day.
Yin's 28-under is tied with Lydia Ko (2021 at Kapolei) for the third-lowest score in relation to par ever for a 72-hole LPGA event. Sei Young Kim holds the record by shooting 31-under in 2018 at Thornberry Creek. Shanshan Feng went 29-under the following year at Thornberry Creek.
Sunday's victory is the California native's second LPGA title after winning the Buick LPGA Shanghai in 2023. Yin is a two-time major runner-up -- at the 2023 Chevron Championship and the 2019 U.S. Women's Open.
Yin's best finish in four previous appearances at LPGA Thailand was a share of third place in 2021.
"I wasn't that comfortable because Akie shot 10-under the first day and this course is very gettable," Yin said. "So I just had to keep my head down."
Iwai was in stunning form as her 10 birdies got the 22-year-old sponsor invite within one shot of Yin with two holes to play, but a lone bogey at the par-4 17th ended her challenge.
Thai players completed the top five with Jeeno Thitikul, runner-up in 2021, posting a 67 to finish in third at 21-under 267.
Patty Tavatanakit (65) and Moriya Jutanugarn (68) were in a tie for fourth at 19-under 269.
The event is the first stop of the LPGA's so-called Asian swing before the tour moves to Singapore and China over the next two weeks.
