Miyu Yamashita etched her name alongside the greats of the LPGA Tour by matching the 72‑hole scoring record while securing a resounding nine‑stroke triumph at the CPKC Women’s Open in Edmonton. The Japanese phenom closed the tournament with a birdie on the final hole, capping a flawless four‑under 66 in the last round and bringing her tournament total to an astonishing 23 under par, or 257 strokes.
This performance not only earned her a wire‑to‑wire victory but also tied the all‑time low‑score mark that has only been achieved once before on the Tour. The previous holder of the 257‑stroke total was Sei Young Kim, who recorded the same figure at the 2018 Thornberry Creek LPGA Classic in Wisconsin, finishing at 31 under par. Yamashita, however, set a new benchmark for the Canadian national championship by expanding the margin of victory to nine strokes, shattering the previous tournament record set by Jin Young Ko, who posted a 262 in 2019 at Magna in Aurora, Ontario. Yamashita entered the competition with a one‑stroke lead after the opening round on Thursday, thanks to a course‑record 62.
She followed that with a solid 64 on Friday, which gave her a five‑stroke cushion over the field. A 65 on Saturday further extended her advantage to six strokes heading into the final round at Royal Mayfair. Her relentless consistency allowed her to widen the gap to nine strokes by the end of the day, a margin that underscores her dominance throughout the week.
The victory adds a fifth LPGA Tour title to Yamashita’s résumé, each earned in a different country, highlighting her global versatility. Earlier in June she captured the Meijer LPGA Classic in the United States, following a breakthrough major win at the AIG Women’s Open in Wales and a Maybank Championship triumph in Malaysia the previous year. In addition to her international successes, she boasts 13 victories on the Japan LPGA Tour, cementing her status as one of the most accomplished players of her generation. Yamashita was not alone in representing Japanese talent on the leaderboard.
Fellow countrywoman Yuri Yoshida finished second, posting a total of 14 under par after a steady closing 69. Sei Young Kim, the 2018 record‑holder, trailed by a single stroke with a final‑round 67, underscoring the competitive depth of the field. Among the younger competitors, 17‑year‑old Canadian Anna Huang emerged as the top local player, carding an impressive 65 in the final round to tie for fourth place at 12 under par.
Another rising star, 16‑year‑old amateur Aphrodite Deng—who captured the 2025 U.S. Girls’ Junior title—finished tied for seventh with an 11‑under total after shooting a 67 on Sunday. Two‑time LPGA winner Brooke Henderson concluded the tournament at seven under par following a closing 70, while world No. 1 Nelly Korda posted a 69 to finish five under.
The event also served as a crucial qualifier for the upcoming Solheim Cup, with Allisen Corpuz, Andrea Lee and Alison Lee earning automatic spots on the United States team. US captain Angela Stanford is slated to announce her final three selections on Monday, August 24.
