Miyu Yamashita matched the LPGA Tour’s historic 72‑hole scoring benchmark by posting an overwhelming nine‑stroke triumph at the CPKC Women’s Open, cementing her status as one of the sport’s brightest talents. The Japanese phenom closed out the final round on Sunday with a decisive birdie, finishing the day at four under par with a 66. That round brought her tournament total to an astonishing 23 under par, or 257 strokes, and secured a wire‑to‑wire victory on the Edmonton course.
Yamashita’s 257 total ties the record set by Sei‑Young Kim at the 2018 Thornberry Creek LPGA Classic in Wisconsin, where Kim posted a 31‑under finish. The Japanese star had already been one stroke ahead after the opening round on Thursday, thanks to a course‑record 62. She followed that with a 64 on Friday, expanding her lead to five strokes, and then a 65 on Saturday, further widening the gap. Entering the final day at Royal Mayfair, Yamashita held a six‑stroke advantage, which she turned into a nine‑stroke margin, shattering the previous tournament record for the Canadian national championship.
The former record of 262, set by Jin‑Young Ko in 2019 at Magna in Aurora, Ontario, was comfortably eclipsed. Yamashita’s résumé on the LPGA Tour is notable for its geographic diversity. She has captured four Tour titles in four different countries. In June she triumphed at the Meijer LPGA Classic in the United States, following her maiden major win at the AIG Women’s Open in Wales and a victory at the Maybank Championship in Malaysia the year before.
In addition to her international success, she boasts 13 wins on the Japan LPGA Tour, underscoring her consistency across both domestic and global stages. The tournament also highlighted strong performances from fellow Japanese competitors. Yuri Yoshida finished second, carding a 14‑under total after a closing 69.
Sei‑Young Kim, the 2018 record‑holder, was just one stroke behind Yoshida, posting a final‑round 67. Young talent featured prominently throughout the event.
Seventeen‑year‑old Anna Huang emerged as the top Canadian player, posting an impressive 65 in the final round to finish tied for fourth at 12 under par. Sixteen‑year‑old amateur Aphrodite Deng, who captured the 2025 U.S. Girls’ Junior title, tied for seventh with an 11‑under finish after a 67 on Sunday. Veteran competitors also made their mark.
Two‑time winner Brooke Henderson concluded the tournament at seven under after a closing 70, while world No. 1 Nelly Korda recorded a 69 to finish at five under. The week also served as a qualifier for three spots on the United States Solheim Cup team.
Allisen Corpuz, Andrea Lee, and Alison Lee earned their places, leaving captain Angela Stanford with three final selections to announce on Monday, August 24. The Solheim Cup, scheduled for September 11‑13, will see Team Europe attempt to reclaim the trophy, with all three days broadcast live on Sky Sports Golf.
