New York, US Open 2025 – World No. 1 Jannik Sinner opened his US Open title defence in emphatic fashion, defeating Czech qualifier Vit Kopriva in straight sets on Arthur Ashe Stadium.
The Italian superstar needed just one hour and 38 minutes to cruise to a 6-1, 6-1, 6-2 victory, underlining why he remains the man to beat at Flushing Meadows this year. The win comes as reassurance to fans after Sinner was forced to retire from the Cincinnati Open final against Carlos Alcaraz last week due to illness.
“I’m very happy to be healthy again,” said Sinner after his commanding first-round win. “We worked hard to arrive here in the best possible condition.”
Sinner Extends Hard-Court Grand Slam Dominance
Kopriva, ranked 89th in the world and making his main-draw debut at the US Open, found no answers to Sinner’s relentless baseline game. The defending champion has now won 22 consecutive matches at hard-court Grand Slams, a streak that stretches across multiple majors.
Sinner has lifted three of the last four Grand Slam titles — the 2023 US Open, the 2024 Australian Open, and most recently, Wimbledon 2025. His only loss at a major this season came in the French Open final against Alcaraz, a five-set thriller.
“I have great memories from winning here last year,” Sinner reflected. “But every Grand Slam feels new. The emotions are strong, and I’m excited to compete against the best players again.”
Next Match: Sinner vs Popyrin
In the US Open 2025 second round, Sinner will face Australia’s Alexei Popyrin (world No. 36), who advanced with a straight-set win over Emil Ruusuvuori of Finland.
