Japanese golfer Akie Iwai secured her first LPGA Tour victory by winning the Portland Classic with a score of 24-under par. Iwai shot a final round 66, including six birdies, to finish four strokes ahead of her nearest competitors. This win marks a historic moment as she and her twin sister, Chisato Iwai, both claimed LPGA titles in their rookie seasons on the U.S. tour, with Chisato having won the Mexico Riviera Maya Open in May. The Iwai twins are the first siblings to achieve LPGA Tour victories in the same season. Akie Iwai's triumph at the Portland Classic also represents the fifth win by Japanese players on the LPGA Tour this season. Her twin sister Chisato finished tied for third in the same tournament, underscoring their competitive presence on the tour. The Portland Classic victory took place in Oregon, adding a notable location context to the achievement.
