Fullerton offered no soft entry. On 26 June 2026, at the BWF US Open, an 18-year-old ranked 80th in the world stood across the net from the men's singles top seed and did not blink. Rounak Chouhan beat Chou Tien Chen, the former world No. 6 from Chinese Taipei, 21-17, 26-24 in 49 minutes to reach the quarterfinal. The biggest win of his career, delivered without the tremor his years might have excused.
The match turned twice, and both times against the odds. Down 15-17 in the opening game, Chouhan rattled off six unanswered points to claim the opener. The second game looked to be slipping away when Chou Tien Chen built a 17-11 advantage, but the Indian mounted another comeback, reeling off six consecutive points to draw level before saving four game points and converting his second match point. Neck and neck to the last exchange, he held his nerve where the older man's began to fray.
The composure of the youngest man on court
What carried him was patience, and an absence of fear. Chouhan produced a fearless display to overcome the vastly more experienced Taiwanese. He said as much afterwards. Speaking to the Badminton Association of India, he explained that he had gone in without pressure, believing he could pull off the match because he was the youngster. He also credited his mind: he had worked on his patience, and his smashes were working well.
"I had no pressure before the match because I am the youngster," he told the Badminton Association of India.
The quarterfinal was not a first flourish but the crest of a full week. Chouhan had battled through the qualifying rounds with victories over France's Enogat Roy and Chinese Taipei's Kuo Kuan Lin before defeating former World Junior Championships silver medallist S. Sankar Muthusamy in an all-Indian second-round contest. Four matches, then, to reach the last eight, each demanding more than the last. The reward was a meeting with Israel's Misha Zilberman.
A trajectory taking shape
The result reads as a leap because the ranking gap was wide, but it did not come from nowhere. Chouhan is a member of India's bronze medal-winning squad at the World Junior Championships , and the junior grounding has begun to translate to the senior circuit. He framed it plainly: performing at senior level, he said, gives him confidence, and he intends to carry the same mindset into the matches ahead. The intent held. Beyond Fullerton's quarterfinal lay a semifinal run, but the Chou Tien Chen match remains the hinge, the afternoon the tour learned his name.
For a teenager ranked 80th, the top seed was meant to be the ceiling. Chouhan treated him as a door.
