PORTLAND, Ore. – In a historic moment for women's golf, Japan's Akie Iwai won the LPGA Standard Portland Classic on Sunday, completing a rare sibling sweep of titles on the tour this year. With this win, she joins her twin sister, Chisato Iwai, as a champion in the 2025 LPGA season.

The 22-year-old LPGA rookie carded a final-round 6-under 66 at the Columbia Edgewater Country Club, finishing with a commanding total of 24-under 264. She secured a comfortable four-stroke victory over runner-up Glynn Corr of the United States and took home the top prize of $300,000. Her twin, Chisato Iwai, who won the Riviera Maya Open in May, also had a strong performance, finishing in a tie for third place at 19-under.

The Iwai twins are now the fourth pair of sisters to win on the LPGA Tour, following Annika and Charlotta Sörenstam, Ariya and Moriya Jutanugarn, and Jessica and Nelly Korda. This achievement further solidifies their place in golf history.

Iwai's victory marks her first on the LPGA Tour after previously winning six times on the Japan Ladies Professional Golf Association (JLPGA) Tour in 2023 and 2024. Her win also extends a remarkable streak for the 2025 LPGA Tour season: no player has yet won twice in 21 tournaments, a record in tour history for the longest stretch without a multiple-time winner.

Japanese golfers have had an exceptional season, with five players—Rio Takeda, Mao Saigo, Miyu Yamashita, and the Iwai sisters—securing five victories, the most of any country this season. The United States has three wins, while Australia and Sweden each have two. South Korea has also been a strong contender with five different champions—A Lim Kim, Hyo Joo Kim, Hae Ran Ryu, So Mi Lee, and Jin Hee Im—though their five wins only count for four tournaments, as Lee and Im won the two-person Dow Championship.

Among the top finishers at the Portland Classic were two South Korean golfers, Sung Hyun Park and Hae Ran Ryu, who tied for seventh place at 16-under 272. This marked a significant return to form for former world No. 1 Sung Hyun Park, who secured her first top-10 finish since the 2019 AIG Women's Open, a six-year hiatus from the top of the leaderboard.

This season continues to be a testament to the global talent and rising stars in women's golf.
