The 2026 FM Championship round one leader is Sei Young Kim, and she did not arrive there by nudging a few putts around the edge.

The world No. 9 opened with an 8-under 64, the lowest first round in tournament history, to take a one-shot lead over Emily Kristine Pedersen and Miyu Yamashita.

Kim’s 64 sets the opening-round mark

Kim’s card contained the sort of stretch that can make a Thursday leaderboard look prematurely serious: four birdies and an eagle across six holes. She needed only 24 putts, tied for the fewest in the field, and finished at 8-under.

The distinction matters. A 64 is not the FM Championship’s outright 18-hole record — Haeran Ryu and Jin Hee Im share that at 62 — but nobody has opened this event lower. For a player already holding the tournament’s 36-hole scoring record of 130 from 2025, the course is hardly an unfamiliar accomplice.

Kim also felt the course and greens were playing softer than last year, creating more opportunities to attack.

There is some recent evidence that this scoring gear is not a one-day curiosity. She shot 64 in the third round of last week’s CPKC Women’s Open, where she finished third. This is the first time she has led or co-led since the third round of the 2026 U.S. Women’s Open presented by Ally.

Kim has six top-10 finishes from 15 starts this season, with 12 cuts made and a best result of runner-up at the JM Eagle LA Championship presented by Plastpro. Half of those top 10s have been top-three finishes.

The missing item is a 2026 victory. After Thursday, it is no longer hiding very discreetly.

Pedersen finds a round worth keeping

Pedersen’s 65 was her lowest LPGA Tour round since the third round of the 2024 Honda LPGA Thailand and put her in her best post-round position since she sat tied second after the third round of the 2023 Dana Open.

That context gives the score some weight.

A wrist injury kept her out for the first four months of the season, and after returning at the Mizuho Americas Open she missed six cuts in eight events. Golf can be generous with fresh starts in theory and rather less enthusiastic about supplying them in practice.

“It’s nice. I think it’s getting tougher and tougher. The girls and the level out here are better every year. Obviously there is still a few of the ones that I grew up with still out here, which is nice to see. They’ve all been doing quite a bit better than I have. I still feel like my good golf is good and I still feel that I haven’t peaked or reached the point that I have yet, so it’s nice to see that I can have a day like today.”

One round does not repair a season, but a 65 against this field is at least a persuasive opening argument.

Yamashita makes 10 birdies and still trails

Yamashita’s route to 65 was considerably less tidy and possibly more entertaining.

She made 10 birdies, the most in the field, including seven in an eight-hole stretch on the back nine for a back-nine 30.

She also made double-bogey at the par-3 eighth.

Ten birdies will usually purchase a little more privacy at the top of a leaderboard, but golf insists on keeping receipts.

The rest of the numbers were formidable. Yamashita hit every fairway and matched Kim’s 24 putts, tied for the fewest in the field. She also arrived after tying the LPGA Tour’s 72-hole scoring record last week, so another low number hardly came from nowhere.

Asked which part of her game was best, she kept the review brief: “Today putting, middle putting, so, yeah, good. So good.”

The card was rather more expansive.

Darquea lands the cleanest shot of the day

Daniela Darquea supplied Thursday’s most economical highlight with a hole-in-one at the 11th, using a 6-iron from 160 yards.

No recovery shot, no awkward two-putt, no committee meeting over the line. Just one swing and a number the scorecard could cope with.

Amy Yang’s opening round ended differently, with a withdrawal due to injury.

Kim has the lead — and useful history here

Kim’s position is hardly a surprise in career terms. She owns 13 LPGA Tour victories, 86 career top-10 finishes and one major championship, the 2020 KPMG Women’s PGA Championship. Her most recent win came at the 2025 BMW Ladies Championship in Korea.

She also finished third at the FM Championship in 2025. So Thursday’s 64 has both immediate force and a little local precedent.

The more interesting question is how much separation she can create from two very different challengers.

Pedersen is trying to turn one excellent round into evidence that her season has changed direction. Yamashita has just produced 10 birdies while leaving enough mistakes on the card to suggest 65 was not the limit.

Kim leads by one. After a record opening round, that is the comfortable part.

The awkward part for everybody else is that 64 looked less like a ceiling than a warning.
