Akie Iwai reacts after her putt on the ninth green during the final round of the 2025 Standard Portland Classic at Columbia Edgewater Country Club.

The LPGA was oh-so-close to having twin sisters finish 1-2 in a tournament. While that came up just short of happening, Sunday did produce the second half of twin wins in 2025.

The winner of the 2025 Standard Portland Classic was Akie Iwai, an LPGA rookie who finished 23 under to win by four shots over Gurleen Kaur. She joins twin Chisato as a winner this season. Chisato won the 2025 Mexico Riviera Maya in May. Akie is older by one minute. She's the fourth rookie from Japan (and sixth rookie overall) to win on the LPGA in 2025 and the 22nd different player overall from Japan to claim an LPGA win. She's also the 10th first-time winner on the LPGA in 2025.

Akie shot 67-67-64-66 at Columbia Edgewater to win for the first time on the LPGA. She went bogey-free on Sunday. She's now played in 17 events and has made 12 cuts.

This week also marks her fourth top-10 finish. During a season when Japanese players won the first and last majors on the calendar, Akie is the latest from Japan to win on the LPGA.

Chisato shot a final-round 64, the round of the day Sunday, and she finished 19 under, five back of big sister.
