LAS VEGAS, Nev. – Reigning U.S. Open Women’s Singles Champion Yan Guo successfully defended her title at the 2025 U.S. Open, capturing the gold medal with a hard-fought victory over Sun Chen in the women’s final. Guo prevailed 4–1 (12–10, 8–11, 13–11, 11–2, 14–12), replicating her podium finish from a year ago.

Guo was once again a dominant force throughout the singles competition and appeared largely unchallenged until an electrifying final against Chen. The matchup featured two of the fastest players in the field, whose speed and precision set them apart in their pursuit of the championship.

“I had to try my best because at this stage all the players are similar in skill level,” Guo said after the match. “We both tried very hard. This finish was of the best athletes enduring the event. I’m just happy to be the champion again. I’m excited because I won last year and could continue winning.”

The final opened dramatically, with Guo trailing 10–7 in the first game. Maintaining her composure, she rattled off five consecutive points to steal the opener and establish momentum. Aside from a lopsided fourth game dominated by Guo, the contest between the two Chinese nationals remained tight until the final points were decided.

On the men’s side, Minseo Oh captured his first U.S. Open Men’s Singles gold medal in a thrilling seven-game battle against Koyo Kanamitsu, winning 4–3 (11–7, 11–6, 11–8, 5–11, 11–3, 10–12, 11–8).

“This is my first time visiting the United States, and I’m very happy to win,” Oh said. “I loved representing the Seoul team, and I was honored to play with such high-level players here.”

The victory marked Oh’s first appearance in an International Open tournament, and the singles championship carried special significance for the Korean standout. In the final, Oh and Kanamitsu matched intensity, showcasing exceptional speed and athleticism. Oh surged to an early three-game lead before Kanamitsu mounted a comeback, relying on his backhand to claw his way back and level the match at three games apiece.

In the decisive seventh game, Oh found a second wind and regained his composure. He relied on his dominant forehand, opening with a five-point barrage to get in front. Oh went on hold off his Japanese opponent down the stretch to secure the title, and his breakthrough victory closed out another memorable and exciting year of elite competition.
