Like a thunderbolt from the clear Sunday sky, Korea’s Doyeob Mun pulled off one of the most spectacular final-round performances in Asian Tour history, storming through the field with a flawless eight-under-par 63 to win the 2025 GS Caltex Maekyung Open.

Starting the day six shots off the lead and well ahead of the final pairing, the 33-year-old Mun lit up Namseoul Country Club’s notorious back nine with a run of six birdies—including a jaw-dropping stretch of four straight from the 11th hole. His dazzling play vaulted him to a 10-under-par total and a three-shot victory over Thailand’s Jazz Janewattananond and fellow Koreans Baekjun Kim and Junghwan Lee.

“I couldn’t be happier to be on top of the leaderboard in a tournament I’ve always wanted to win,” Mun said emotionally. “When the birdie putt on 18 went in, I thought I could at least make it to a play-off. I told my caddie we needed that birdie—and I’m glad we made it.”

Mun’s victory marks his first Asian Tour win and his fourth Korean PGA Tour title. His aggressive yet precise second shot on the par-four 18th landed just six feet from the pin, sealing one of only three birdies on the closing hole all day.

With two hours to wait as the final groups closed in, Mun could only practice on the range and hope. Eventually, the leaderboard broke his way.

Jazz Janewattananond, tied for the lead at the start of the day, faltered late. He missed makeable birdie opportunities on 14 and 15 and bogeyed the last, finishing in a tie for second.

“It was a grind fest out there,” said Jazz. “I gave it everything I had, but Doyeob just played phenomenal golf. Honestly, I don’t know how he shot eight-under today. If it wasn’t for him, I might’ve had a chance at a play-off.”

Canadian Yonggu Shin briefly threatened after birdies on 13 and 14, but a bogey on 17 and a disastrous 10 on 18 derailed his title hopes. He finished tied for 12th.

Scott Vincent of Zimbabwe, also in the hunt entering Sunday, collapsed with a 75 that included a double bogey and three bogeys, likewise finishing in a tie for 12th.

Namseoul Country Club, often regarded as one of the most punishing layouts in Asian golf due to its mountainous terrain and slick, undulating greens, was no match for Mun’s brilliance. His 63 fell just two shots shy of the course record.

The GS Caltex Maekyung Open, co-sanctioned with the Korean PGA, has now crowned a local champion for the 21st straight year, denying Jazz’s bid to end the streak.

As the Asian Tour shifts to Japan for the US$2 million International Series event at Caledonian Golf Club from May 8 to 11, all eyes will be on Mun, the man of the moment, who proved that even six shots back, victory is never out of reach.
