Miyu Yamashita delivered a performance that will be remembered for years to come when she matched the LPGA Tour's all‑time 72‑hole scoring record during her emphatic win at the CPKC Women’s Open. The Japanese prodigy closed out the tournament with a birdie on the final hole on Sunday, sealing a four‑under 66 in the last round and bringing her tournament total to an astonishing 23 under par, or 257 strokes.
That score not only gave her a nine‑stroke margin of victory but also placed her on a tie with the historic 257‑stroke total posted by Sei Young Kim at the 2018 Thornberry Creek LPGA Classic in Wisconsin, where Kim finished 31 under. Yamashita entered the final round already in command after a blistering start to the week. She opened with a course‑record 62 on Thursday, which put her one stroke ahead of the field. She followed that with a 64 on Friday, extending her lead to five strokes, and then a 65 on Saturday, further widening the gap to six strokes as she headed into the final day at Royal Mayfair.
On Sunday she turned that six‑stroke cushion into a nine‑stroke triumph, setting a new tournament record for the Canadian national championship and eclipsing Jin Young Ko’s previous benchmark of 262 set in 2019 at Magna in Aurora, Ontario. The victory added another chapter to Yamashita’s rapidly growing résumé. She now boasts four LPGA Tour titles, each earned in a different country, underscoring her ability to adapt to a variety of courses and conditions. Earlier in June she captured the Meijer LPGA Classic in the United States, and she previously claimed her first major at the AIG Women’s Open in Wales.
In addition, she won the Maybank Championship in Malaysia last year. On the Japan LPGA Tour she has amassed 13 victories, confirming her status as one of the most successful Japanese players of her generation. The leaderboard behind Yamashita also featured notable performances. Fellow Japanese competitor Yuri Yoshida finished second, carding a closing 69 to end the week at 14 under par.
Sei Young Kim, the co‑holder of the 257‑stroke record, was a single stroke behind Yoshida after posting a 67 in the final round. Young Canadian Anna Huang, only 17, emerged as the top‑finishing player from the host nation, posting a 65 on Sunday to tie for fourth place at 12 under. Sixteen‑year‑old amateur Aphrodite Deng, who captured the 2025 U.S. Girls’ Junior title, tied for seventh with a 67, finishing 11 under.
Two‑time Canadian champion Brooke Henderson recorded a solid 70 in the final round to finish at seven under, while world number one Nelly Korda carded a 69 to end the tournament five under. The event also served as a qualifying arena for the upcoming Solheim Cup, with Allisen Corpuz, Andrea Lee and Alison Lee securing their spots on the U.S. team. Team captain Angela Stanford is expected to announce her remaining three selections on Monday, August 24.
The CPKC Women’s Open win not only solidified Yamashita’s place among the elite but also highlighted the growing depth of talent on the LPGA Tour. Her ability to dominate from start to finish, posting four consecutive rounds under 66, demonstrates a level of consistency and mental toughness that is rare even among the sport’s best.
As the season progresses, all eyes will be on her to see if she can continue to challenge records and add more titles to her impressive collection. For fans wanting to relive the action, the tournament was streamed live on various platforms, and highlights are available through the Sky Sports Golf Podcast and other streaming services. The event also generated excitement about the upcoming Solheim Cup, scheduled for September 11‑13, where Team Europe will look to reclaim the trophy from the United States.

The course’s demanding greens, strategic bunkering, and variable weather conditions made Yamashita’s record‑tying performance all the more impressive.
As the LPGA Tour continues to expand its global footprint, events like this one in Canada highlight the sport’s international appeal and the rising stars who are shaping its future. In summary, Miyu Yamashita’s nine‑stroke victory at the CPKC Women’s Open not only tied the historic 257‑stroke mark but also set a new tournament record, underscoring her status as a dominant force on the LPGA Tour. With multiple titles across four continents, a major championship under her belt, and a growing list of impressive finishes, Yamashita is poised to remain a central figure in women’s golf for years to come.
