Andy DevaneyThe 2026 CPKC Women’s Open round 3 leader, Miyu Yamashita, has given everybody else a fairly unappealing Sunday assignment.
The Japanese star reached 19 under through 54 holes, matching the LPGA Tour record with a total of 191 and opening a six-shot advantage over Gina Kim and Yuri Yoshida.
For perspective, Yamashita has not merely produced the lowest 54-hole score of her own career. She has beaten her previous best by nine shots. At that point, improvement starts to look less like progress and more like somebody finding a trapdoor in the scoring system.
Her 191 equals the LPGA Tour mark set by Hyo Joo Kim at the 2026 Ford Championship presented by Wildhorse Pass. It also adds another tournament record to Yamashita’s week after she established the CPKC Women’s Open 36-hole mark at 126.
There are still 18 holes to negotiate. Six shots, however, is the sort of cushion that tends to make the chasing pack look at the leaderboard rather more often than they intended.
Yamashita’s putter has done considerable damage
The headline number is 19 under, but the detail explaining it is equally persuasive.
Yamashita has needed just 79 putts through three rounds, the fewest in the field. She has also made a tournament-leading 22 birdies. Those figures are not especially conducive to allowing rivals back into a golf tournament.
This is the first time in Yamashita’s LPGA Tour career that she has held a lead after 54 holes. Her previous best position through three rounds was tied second at the 2024 KPMG PGA Championship.
Asked about matching the scoring record, Yamashita offered a rather less complicated assessment than the numbers might suggest.
“So this course I like, so I like this course, yeah.”
Hard to argue with the evidence.
The performance is also arriving on her first appearance at the CPKC Women’s Open. Yamashita entered the week ranked seventh in the Rolex Rankings and fifth in the 2026 Race to the CME Globe, with one victory and eight top-10 finishes this season.
Gina Kim applies pressure with a career-best 64
Yamashita’s lead might be commanding, but it was not created because everyone behind her spent Saturday folding deckchairs.
Gina Kim produced a 64 to reach 13 under, tying the best round of her LPGA Tour career. Her previous 64 came at the 2023 The Standard Portland Classic.
Kim made seven birdies against a single bogey in round three and has hit 46 of 54 greens in regulation through three rounds, tied for the best mark in the field.
Her description of the examination explains why that accuracy has mattered.
“Yeah, obviously the rough is really thick and gnarly, and if you’re not in the fairway you’re penalized a lot for it. So I think this course is tough but it’s fair, and if you can capitalize on the ones in the fairway, you’re usually in a pretty good spot which is what I’ve been trying to do. So it’s been good.”
A six-shot deficit is substantial. Shooting 64 and discovering that you remain six behind is also one of golf’s more character-building experiences.
Yuri Yoshida stays in the chase at 13 under
Yuri Yoshida shares second place after a second consecutive 66 took her to 13 under.
Her 197 total is the lowest 54-hole score of her LPGA Tour career, improving on the 200 she recorded at the 2023 TOTO Japan Classic. She also ranks inside the top 10 this week for both birdies, with 17, and fewest bogeys, with four.
Yoshida was rather more enthusiastic about the front half of her Saturday than the back.
“Front nine was really good. I got three birdies. But back nine was I think not my time.”
That leaves Yoshida alongside Kim as the closest challenger, although both require something more substantial than merely solid golf on Sunday. Yamashita has rather raised the entrance requirements.
Even the chasing pack is struggling to explain 19 under
Jennifer Kupcho’s reaction perhaps best captured the scale of Yamashita’s scoring.
“Yeah, I mean, I don’t know what golf course she’s playing because 18-under is insane, but, yeah, I mean, I’m just going to go out there and play my best. Like there is nothing you can do if she’s playing lights out. It is what it is, you know, so..”
Yamashita has since reached 19 under, which hardly improves the mathematics for those pursuing her.
The more serious point is that she has combined birdie volume with remarkable efficiency on the greens. Twenty-two birdies and 79 putts across 54 holes leave precious few obvious weaknesses for the field to attack.
Victory would put Yamashita into rare company
Sunday carries considerably more significance than another trophy.
Victory would be Yamashita’s fourth on the LPGA Tour and her second of the 2026 season. It would make her a multiple winner this year alongside Jeeno Thitikul, Haeran Ryu, Nelly Korda, Hyo Joo Kim and Hannah Green.
She would also become the fastest Japanese player to reach four LPGA Tour victories, doing so in 42 starts, while her four wins would have come in four different countries: Canada, the United States, Malaysia and Wales.
Only Ha Na Jang has recorded at least four victories across four or more countries.
Yamashita would additionally become the second Japanese player to record multiple victories in consecutive seasons, following Ayako Okamoto, who achieved three successive multi-win campaigns from 1986 to 1988.
There is a wire-to-wire distinction available too. A victory would make Yamashita the fourth such winner on the LPGA Tour in 2026, joining Nelly Korda, Lauren Coughlin and Jenny Shin.
Those records can wait until the final putt. For now, the equation is simpler: Yamashita has 18 holes left, six shots in hand and a scoring record already safely written beside her name.
The field still has a chance. It may first need Yamashita to start playing the same golf course as everybody else.
