Choi closed Sunday with a 4-under 67, making five birdies and one bogey in the final round at Seowon Valley Country Club’s Valley-Seowon course (par 71) in Paju, Gyeonggi Province.
He finished at 13-under 271, beating Jang Yu-bin and Jung Tae-yang, who tied for second at 10-under 274, by three strokes. It was Choi’s first win in 32 starts on the regular tour. His previous best was a tie for fourth at the season-ending Championship in November last year.
Choi earned 300 million won in prize money and secured a two-year tour exemption. The payout was nearly double his cumulative earnings of 175.14 million won from his previous 31 events.
Last week, Choi shared the first-round lead at the season-opening DB Insurance Promy Open but faded to a tie for 34th. This week, he moved into contention from the second round and held on for the title.
“I never even dreamed I could win. It still doesn’t feel real,” Choi said in a postround TV interview. “It was difficult at first. I’m grateful to my parents for waiting and supporting me.”
Jang, who returned after playing LIV Golf, settled for second at 10-under 274.
Defending champion Lee Tae-hoon of Canada finished tied for fourth with Kim Baek-jun and others at 9-under 275.
Im Sung-jae, the 2023 and 2024 champion who entered the event while visiting South Korea during the PGA Tour season, tied for 39th at 2-under 282.
