S-10: Top 30 point leaders in the 2025 LPGA Tour's Race to the CME Globe

Iwai, who competes on the LPGA Tour along with twin sister, Aikie, is making her fourth start in the U.S. Women's Open, thanks to being among the top 30 point leaders in the 2025 Race to the CME Globe on the LPGA Tour. She also became the third player from Japan to claim a title on the LPGA Tour in 2025 when she claimed the Mexico Riviera Maya Open at Mayakoba by six strokes over fellow rookie Jenny Bae. Chisato carded a final-round 66 to join Chevron Championship winner Mao Saigo and Rio Takeda as LPGA Tour winners from Japan in 2025. Chisato also owns eight victories on the LPGA Tour of Japan, three coming in the 2024 campaign.
