Chou Tien-chen has reached the men's singles quarterfinals five times in the World Tour this season, continuing his pursuit of the season's first title.

On the 27th, Chou Tien-chen, the top player from Chinese Taipei, defeated Vietnam's Nguyen Hai Dang with scores of 21-17, 21-17 at the Super 300 Series 2025 US Open Badminton Championships. This marks his fifth appearance in the men's singles quarterfinals this season, but unfortunately, he missed the chance to compete against his teammate Su Li-yang in an internal battle of Chinese Taipei.

The BWF World Tour reignited its competition in North America, with Chou Tien-chen, ranked sixth in the world, reaching the finals of the Indonesia Open, becoming the oldest player to qualify for a 1000-level final and taking home the runner-up title. He has no plans for a break and is set to compete in the US Open as originally scheduled, entering as the top seed in men's singles, seeking his first championship of the season.

In the first round, Chou Tien-chen defeated Finnish player Kalle Koljonen with scores of 24-22, 21-15, and faced world-ranked 73 Nguyen Hai Dang today. The two had previously met at the 2023 Asian Championships, where Chou won in straight sets.

Although Chou Tien-chen fell behind after losing five consecutive points when leading 12-10 in the first game, he stabilized at a crucial moment, scoring four consecutive points at 17-17 to take the first game.

The 24-year-old Nguyen Hai Dang qualified for the Paris Olympics last year and had previously caused a scare for current world champion Kunlavut Vitidsarn during the 2023 Hangzhou Asian Games. In the second game, he responded well, initially leading 14-7, but Chou regained control with a 12-2 run, winning in straight sets to secure his advancement.

There were hopes for an internal battle in the quarterfinals with Chou Tien-chen, but Su Li-yang lost to Canada's Lai Hao-jun with scores of 18-21, 13-21, meaning Chou will compete against Lai for a spot in the semifinals.
