Miyu Yamashita made history at the CPKC Women’s Open by equalling the LPGA Tour’s all-time 72‑hole scoring benchmark, finishing the tournament with a staggering nine‑stroke lead. Her final round was a flawless 66, four strokes under par, which lifted her weekly total to 23 under par, or 257 strokes overall. This performance secured a wire‑to‑wire triumph in Edmonton and placed her alongside the few elite players who have managed such a low aggregate on the tour. The Japanese prodigy capped her victory with a decisive birdie on the 18th hole on Sunday, a finishing touch that underscored her dominance throughout the four‑day event.
By the end of the tournament she had not only matched the 257‑stroke record set by Sei Young Kim at the 2018 Thornberry Creek LPGA Classic in Wisconsin, but also set a new tournament record for the Canadian national championship, surpassing Jin Young Ko’s previous best of 262 set in 2019 at Magna in Aurora, Ontario. Yamashita entered the final round already six strokes ahead after posting a 62 in the opening round – a course‑record that gave her an early advantage. She followed that with a 64 on Friday, extending her lead to five strokes, and a 65 on Saturday, further solidifying her position. When she stepped onto the 18th tee for the final round at Royal Mayfair, she was already in a comfortable position, but she chose to press on, ultimately widening the margin to nine strokes and cementing her place in the event’s history books.
The victory adds a fifth LPGA Tour title to Yamashita’s résumé, each earned in a different country, highlighting her adaptability and global competitiveness. Earlier in June she captured the Meijer LPGA Classic in the United States, following her breakthrough major win at the AIG Women’s Open in Wales and a triumph at the Maybank Championship in Malaysia last year.
In addition to her international successes, Yamashita boasts 13 victories on the Japan LPGA Tour, underscoring her status as one of the most accomplished players from Japan. Her compatriot, Yuri Yoshida, provided strong support for the Japanese contingent by finishing second, two strokes behind Yamashita at 14 under par after posting a solid 69 in the final round.
Sei Young Kim, the previous holder of the 257‑stroke total, ended the tournament one shot further back after a closing 67. Among the rising stars, 17‑year‑old Anna Huang emerged as the top Canadian finisher, carding an impressive 65 in the final round to tie for fourth place at 12 under par. Sixteen‑year‑old amateur Aphrodite Deng, who captured the 2025 U.S. Girls’ Junior title, also made a notable impact, tying for seventh with a 67 on Sunday and finishing at 11 under.
Two‑time LPGA winner Brooke Henderson concluded the tournament at seven under after a steady 70, while world No. 1 Nelly Korda posted a 69 to finish at five under. The event also served as a qualifier for three spots on the U.S. Solheim Cup team, with Allisen Corpuz, Andrea Lee and Alison Lee earning their places.
Looking ahead, U.S. captain Angela Stanford will announce her final three Solheim Cup selections on Monday, August 24, setting the stage for the upcoming competition. Golf fans can follow Team Europe’s quest to reclaim the Solheim Cup trophy with live coverage on Sky Sports from September 11‑13.
