Staff WriterThe JM Eagle LA Championship had barely taken a breath at El Caballero Country Club before Chizzy Iwai went charging through it like a woman late for a flight and somehow still looking unruffled. The Japanese star opened with a bogey-free 9-under 63, tying the course and tournament record and giving the first-round leaderboard an early shape that looked both tidy and vaguely alarming for everybody else.
A 63 is always a noisy number, but this one had extra bells attached. Iwai made seven birdies, one eagle, hit 11 of 14 fairways, found 17 of 18 greens in regulation and needed only 27 putts. That is not so much a round of golf as a controlled detonation.
Iwai turns the back nine into a blur
The key stretch came on the inward half, where Iwai played her back nine in 7-under 29, the lowest nine-hole score of her LPGA Tour career. It was the sort of run that makes a golf course look cooperative, which it rarely is.
This was also the lowest opening round of her LPGA Tour career, improving on the 6-under 30 she had posted over nine holes at the 2026 Honda LPGA Thailand. More importantly, it placed her in familiar territory. It is the second time she has held the 18-hole lead or co-lead on Tour, and the first time turned out rather well: she shared the opening-round lead at the 2025 MEXCO Riviera Maya Open and went on to win.
That memory matters. So does the broader picture. Iwai arrived in Los Angeles already ranked 10th in the 2026 Race to the CME Globe, with two top-10 finishes in six starts this season and a runner-up result in Thailand. She looks less like a player finding her feet and more like one quietly installing herself among the serious weekly threats on the LPGA Tour.
On her mindset after making five birdies and an eagle during her first nine, Iwai said:
“A little bit thinking 58 or 9 score. But golf is not easy. That’s why I focus my routine. I try myself. I don’t think too much.”
Sensibly enough. The minute golf senses a player getting ideas above her station, it usually responds with a rake to the shin.
A three-way tie keeps the pressure on
A shot further back, the JM Eagle LA Championship leaderboard is anything but sleepy. Suvichaya Vinijchaitham, Sei Young Kim and Patty Tavatanakit all opened with 7-under 65s, each arriving there by slightly different means.
Vinijchaitham’s round was the most volatile of the three and perhaps the most revealing. The 2026 LPGA Tour rookie made nine birdies against two bogeys and caught fire over her second nine, making six birdies and stringing together consecutive gains from holes 14 through 17. She leads the field in birdies after round one, and her 65 stands as the best round of her young Tour career.
For a rookie still adjusting to life at this level, it was a large step forward.
On being a rookie on Tour and her confidence level after her round, Vinijchaitham said: “Yeah, I’m a rookie on Tour. It’s been pretty stressful for me I think. I just think myself out there it’s quite hard. I know I went to college in the U.S., but still there is a lot different. But, yeah, today was a great round for me and kind of like help me build my confidence a little bit, yeah.”
Kim’s 65 had a sturdier, more seasoned feel to it. She hit 17 of 18 greens in regulation, made eight birdies and just one bogey, and used a power game that still has plenty of teeth. Her average driving distance of 300 yards ranked second in the field on Thursday, and when par-5s are playing downwind, that can feel mildly unfair.
On her 7-under opening round at El Caballero Country Club, Kim said: “Yeah, very dry golf course conditions, so greens are really fast. I try to every putt to make the distance. So, yeah, it’s tough, which means I’m not trying too hard, so it makes a lot of birdie on the course.
And then, yeah, par-5 we got the downwind, like couple — two is par-5, so it is big advantage. Is, yeah, reachable. So, hole 16 or — 15 is par-5. I had a pitching wedge to the, yeah, to the pin, the second shot even like par-5. So, yeah, it’s play like really solid today.
Yeah, it’s LA is a great weather always and I’m very happy to walking on the course. Yeah, I’m glad to be back here, yeah, I play very solid. I’m very happy with that.”
Tavatanakit, meanwhile, produced one of the more significant rounds of her season. Her 65 was not only her lowest score of 2026, it was also her lowest round ever at the JM Eagle LA Championship and her first round in the 60s all year. She hit 10 of 14 fairways, found 16 of 18 greens and took 28 putts, a combination that suggests the gears may finally be catching.
On how important it is to be aware of your statistics and yardages, Tavatanakit said: “I think that’s what I find hard to adjust coming back into like full season tournament play. When you stop for a while just kind of been working on your swing and stuff, but you just kind of, you know, not think about hitting the numbers. I feel like I’ve been kind of building that ever since San Francisco, when we were there. I mean, I feel like my game has always been there. Just a little bit here and there is just kind of rusty. But, yeah, just I kept working and I kept hitting on TrackMan, quad, just to see the numbers, spin rate, to pick the right shot for the right situation.”
El Caballero gives up numbers, but not without a warning label
The scoring was excellent, but El Caballero Country Club did not exactly roll over and offer everyone a biscuit. The course played dry, the greens were fast, and players who controlled distance and trajectory were rewarded. That much was obvious from the statistics.
Iwai and Kim both hit 17 greens in regulation. Tavatanakit hit 16. This was not random dart-throwing. It was precise, disciplined scoring on a golf course where the wrong speed on the wrong line can send a tidy round into the nearest hedge.
That is what makes Iwai’s bogey-free card so impressive. Birdies are lovely, but a clean sheet is where the real craft sits. Anyone can sprint downhill; the clever ones know where the cliffs are.
A hole-in-one and a growing donation total
Yu Liu supplied one of the day’s brighter jolts with the first hole-in-one of her tournament career, acing the 15th with a 9-iron from 161 yards. It was the fourth hole-in-one of the LPGA Tour season.
Thanks to CME Group’s charitable initiative, that ace added another $20,000 to the donation total for St. Jude Children’s Research Hospital. The running total now stands at $80,000, with a minimum guaranteed donation of $500,000 in 2026. Golf can be an odd game, but every so often it manages to be both elegant and useful.
What the opening round means
The first round of the JM Eagle LA Championship did not settle anything, but it clarified plenty. Iwai is no longer merely promising; she is proving. Her win at the 2025 MEXICO Riviera Maya Open was not a one-off flare but part of a broader pattern that now includes one LPGA Tour title, seven career top-10s, and a world ranking of No. 20.
Behind her, the leaderboard is stacked with players who have enough pedigree and scoring power to make Friday interesting in a hurry. Kim knows how to contend. Tavatanakit has found a pulse in her season. Vinijchaitham has the carefree danger of a rookie who just discovered she belongs.
And hanging over all of it is that number: 63. At this tournament, at this course, that is the standard on the board now. The rest of the field can either squint at it from a distance or start chasing it with intent.
For one day, though, the story belonged to Iwai, who made Los Angeles look simple, which is a trick few golfers manage and almost nobody sustains.
