Yamashita Matches LPGA Tour Record with Overwhelming Victory at CPKC Women’s Open

Miyu Yamashita etched her name alongside the greats of the LPGA Tour by matching the all‑time 72‑hole scoring benchmark in a commanding nine‑stroke triumph at the CPKC Women’s Open. The Japanese prodigy capped her final round with a birdie on the 18th hole, sealing a four‑under‑par 66 that brought her tournament total to an astonishing 23‑under‑par, or 257 strokes overall.

This performance not only secured a wire‑to‑wire win in Edmonton but also placed her in the elite company of players who have posted similarly low scores in a single event. Yamashita’s 257 total ties the record set by Sei Young Kim at the 2018 Thornberry Creek LPGA Classic in Wisconsin, where Kim finished an incredible 31‑under‑par.

While both players share the same aggregate, Yamashita achieved her mark on a course that presented its own unique challenges, underscoring the versatility and poise she displayed throughout the four days of competition. The Japanese star entered the tournament with a strong start, posting a course‑record 62 in the opening round on Thursday that gave her a one‑stroke lead. She followed that with a 64 on Friday, expanding her advantage to five strokes, and then a 65 on Saturday, further solidifying her position.

By the time she walked onto the first tee for the final round at Royal Mayfair, Yamashita held a six‑stroke cushion over the nearest competitors. She used that margin to launch an aggressive yet controlled attack, ultimately stretching her lead to nine strokes—a new tournament record for the Canadian national championship.

This margin eclipsed the previous best of 262 set by Jin Young Ko in 2019 at Magna in Aurora, Ontario. Yamashita’s resume of success is already impressive.

She has captured four LPGA Tour titles, each in a different country, highlighting her ability to adapt to varying course conditions and cultures. In June she won the Meijer LPGA Classic in the United States, adding to her major victory at the AIG Women’s Open in Wales and a triumph at the Maybank Championship in Malaysia last year.

On top of those international victories, she boasts 13 wins on the Japan LPGA Tour, cementing her status as one of the most dominant players in both domestic and global competition. The tournament also featured strong performances from fellow Japanese competitor Yuri Yoshida, who finished second at 14‑under‑par after posting a solid closing 69.

Sei Young Kim, the co‑record holder, trailed by just one stroke with a final‑round 67. Among the younger talent, 17‑year‑old Canadian Anna Huang emerged as the top‑finishing local player, carding a 65 on Sunday to tie for fourth place at 12‑under‑par. Meanwhile, 16‑year‑old amateur Aphrodite Deng, who captured the 2025 U.S.

Girls’ Junior title, posted a 67 to finish tied for seventh at 11‑under‑par, demonstrating that the next generation is already making its mark on the professional stage. Two‑time LPGA winner Brooke Henderson concluded her round with a 70, ending the tournament at seven‑under‑par, while world No. 1 Nelly Korda posted a 69 to finish at five‑under‑par.

The event also served as a crucial qualifier for the upcoming Solheim Cup, with Allisen Corpuz, Andrea Lee, and Alison Lee securing spots on the United States team. US captain Angela Stanford is scheduled to announce her final three selections on Monday, August 24, adding an extra layer of intrigue to the forthcoming transatlantic showdown. Looking ahead, golf fans can anticipate a thrilling Solheim Cup battle as Team Europe seeks to reclaim the trophy.

The competition will be broadcast live on Sky Sports from September 11‑13, offering comprehensive coverage of all three days. For those interested in playing the sport themselves, there are opportunities to book a round at any of the 1,700 courses across the UK and Ireland, with price‑comparison tools available to find the best deals. In summary, Miyu Yamashita’s performance at the CPKC Women’s Open not only matched a historic LPGA scoring record but also set a new benchmark for winning margin in the tournament's history.

Her ability to dominate from start to finish, combined with her growing list of international victories, signals that she is a formidable contender in any event she enters. As the LPGA Tour moves forward into the remainder of the 2026 season, Yamashita’s achievement will be remembered as a milestone of excellence, inspiring both seasoned professionals and aspiring young golfers alike.
