Miyu Yamashita Maintains Six-Stroke Advantage at Royal Mayfair

Miyu Yamashita carded a 5-under 65 to reach 19-under 191, holding a six-shot lead over Gina Kim and Yuri Yoshida at the CPKC Women's Open.

Miyu Yamashita signed for a 5-under 65 on Saturday to reach a three-day total of 19-under 191, securing a six-stroke cushion at the CPKC Women's Open. The Japanese professional, standing 4-foot-11, navigated the par-70 Royal Mayfair Golf Club layout with precision, recovering from a late bogey on the par-3 17th by rolling in a birdie on the 18th green. Her performance in Edmonton, Alberta, follows an opening-round course record of 62 and a second-round 64, positioning her for a wire-to-wire victory. This dominant display comes on the heels of her June triumph at the Meijer LPGA Classic in Michigan and her previous major success at the Women's British Open.

Key details

Gina Kim surged into a tie for second place by carding a 6-under 64, matching the 13-under 197 total of Yuri Yoshida, who posted a 66. Kim’s bogey-free effort moved her six shots adrift of the lead, while Yoshida remained steady to stay within striking distance. The tree-lined course, situated within a bend of the North Saskatchewan River, provided calm scoring conditions despite a summer of record rainfall that increased the local mosquito population. Yamashita’s 54-hole score of 191 represents one of the lowest three-round totals in the history of this championship.

Jennifer Kupcho occupies the fourth position alone at 12-under 198 after registering a 6-under 64 during the third round. She sits one stroke ahead of Somi Lee, whose 65 brought her to an 11-under 199 aggregate. The leaderboard features a significant gap between the top five and the rest of the field, as Yamashita continues to leverage the momentum from her rookie of the year campaign last season. Her consistency has been the hallmark of the week, hitting fairways at a high rate on the tight, mosquito-heavy Edmonton corridors.

Calgary-born amateur Aphrodite Deng delivered the round of the day, a 7-under 63, to climb into a tie for sixth place at 10-under 200. The 16-year-old, who recently claimed the 2025 U.S. Girls' Junior title, currently stands as the low Canadian in the field. She shares the sixth spot with American Kiara Romero, who carded a 1-under 69. Romero is making her professional debut this week, having earned her LPGA Tour status through the LPGA Elite Amateur Pathway, becoming only the second player to do so after Lottie Woad.

Latest developments

Brooke Henderson, the 2018 and 2025 champion of this event, moved to a 7-under 203 total following a third-round 68. The Canadian favorite remains 12 strokes behind Yamashita but continues to draw the largest galleries at Royal Mayfair. Meanwhile, world number one Nelly Korda sits at 4-under 206 after a Saturday 69, struggling to close the distance on a leader who has not relinquished the top spot since Thursday morning. Korda’s round included three birdies and two bogeys, leaving her in a tie for 22nd place.

Lydia Ko, a three-time winner of this tournament including a victory at this specific venue as a 16-year-old amateur in 2013, posted a 69 to reach 2-under 208. The Olympic gold medalist faced difficult lies in the thick rough but managed to stay under par for the week. The scoring average for the field dropped during the third round as players took advantage of the lack of wind, yet no one could match the sustained pace set by Yamashita’s 19-under-par pace.

Heading into Sunday, the chase pack faces a daunting task to catch the 25-year-old leader, who has recorded only three bogeys over 54 holes of play. The final round will see Yamashita paired with Kim and Yoshida, starting with a six-shot buffer that matches the largest lead entering a final round on the LPGA Tour this season. With the forecast calling for continued mild weather, the scoring record for the CPKC Women's Open remains under threat as the field returns to the North Saskatchewan River valley for the conclusion of the 72-hole event.
