Miyu Yamashita delivered a performance that tied the LPGA Tour’s all‑time 72‑hole scoring benchmark, cruising to a nine‑stroke triumph at the CPKC Women’s Open. The Japanese prodigy sealed her win with a decisive birdie on the final hole on Sunday, capping a flawless four‑under 66 in the closing round. Her aggregate for the tournament stood at 23 under par, or 257 strokes, a total that kept her in the lead from the first tee through to the final putt, establishing a wire‑to‑wire victory in Edmonton.
Yamashita’s 257 matched the score posted by Sei‑Young Kim at the 2018 Thornberry Creek LPGA Classic in Wisconsin, where Kim finished at 31 under. The Japanese star entered the final day already six strokes clear after posting a course‑record 62 in the opening round, followed by a 64 on Friday that extended her advantage to five strokes, and a 65 on Saturday that further widened the gap. When she stepped onto the 18th green at Royal Mayfair for the last round, she was already six shots ahead of the field.
She responded by firing a nine‑stroke winning margin, shattering the previous tournament record for the Canadian national championship and eclipsing Jin‑Young Ko’s 262 total set in 2019 at Magna in Aurora, Ontario. Yamashita’s resume on the LPGA Tour is remarkable for its geographic diversity. She has captured four tour titles across four different nations.
In June she triumphed at the Meijer LPGA Classic in the United States, adding to her first major victory at the AIG Women’s Open in Wales and a win at the Maybank Championship in Malaysia the previous year. In addition to her international successes, she boasts 13 victories on the Japan LPGA Tour, underscoring her dominance both at home and abroad.
The tournament also highlighted the depth of Japanese talent, with compatriot Yuri Yoshida finishing runner‑up at 14 under after posting a solid 69 in the final round. Sei‑Young Kim, the 2018 record‑holder, rounded out the top three, a single stroke behind Yoshida, after a closing 67.
Young Canadian hopefuls made their presence felt as well. Seventeen‑year‑old Anna Huang emerged as the top Canadian finisher, carding an impressive 65 in the last round to tie for fourth place at 12 under. Sixteen‑year‑old amateur Aphrodite Deng, who captured the 2025 U.S.
Girls’ Junior title, finished tied for seventh with an 11‑under total after a 67 on Sunday, showcasing her potential on the professional stage. Veteran Brooke Henderson, a two‑time winner of the event, posted a respectable seven‑under finish after a closing 70, while world number one Nelly Korda recorded a 69 to finish at five under, indicating that the competition remained fierce despite Yamashita’s dominance.
The week also served as a crucial qualifying stage for the upcoming Solheim Cup. Three spots on the U.S.
team were secured by Allisen Corpuz, Andrea Lee, and Alison Lee, who earned their places through strong play throughout the tournament. Team captain Angela Stanford is slated to announce her final three selections on Monday, August 24, completing the roster for the biennial showdown. Looking ahead, golf fans can anticipate the Solheim Cup showdown between Team USA and Team Europe, scheduled for September 11‑13. The event will be broadcast live on Sky Sports Golf, offering an exclusive window into Europe’s quest to reclaim the trophy.
Viewers can stream the action without a long‑term contract, and those interested in playing the sport themselves can find competitive rates and book tee times at over 1,700 courses across the United Kingdom and Ireland. Beyond the headlines, Yamashita’s achievement reflects a broader trend of increasing global representation in women’s golf.
Her ability to win across continents—America, Europe, and Asia—demonstrates the sport’s expanding talent pool and the rising standard of competition. The CPKC Women’s Open, held at the historic Royal Mayfair Golf Club, provided a challenging yet fair test of skill, rewarding precision, strategic course management, and mental resilience. In summary, Miyu Yamashita’s nine‑stroke victory not only matched a historic LPGA scoring record but also set a new benchmark for the CPKC Women’s Open.
Her performance, combined with strong showings from fellow Japanese players, emerging Canadian amateurs, and seasoned veterans, made for a compelling tournament narrative. As the season progresses toward the Solheim Cup, Yamashita’s form positions her as a key contender for future major titles and a prominent figure in the ongoing evolution of women’s professional golf.
