World No.1 Jannik Sinner Advances US Open Second Round After Health Scare

Jannik Sinner, the world number one and defending US Open champion, began his title defense with an emphatic 6-1, 6-1, 6-2 victory over Vit Kopriva, dispelling concerns about his recent illness that forced him to retire from the Cincinnati Open final. Sinner showed no signs of physical trouble, dominating the match in just an hour and 38 minutes with strong serving and precise groundstrokes, extending his winning streak at hard-court Grand Slams to 22 matches. Kopriva, making his US Open main draw debut and ranked 89th, was unable to challenge Sinner, who maintained his momentum after winning the Australian Open and Wimbledon earlier this year. The Italian’s win keeps him in contention for retaining the world number one ranking, with a critical upcoming match against Alexei Popyrin or Emil Ruusuvuori. Sinner’s performance marks him as a strong contender to become the first man to defend the US Open title since Roger Federer’s five consecutive wins ending in 2008. Other notable results included Lorenzo Musetti and Denis Shapovalov advancing to the second round, highlighting the ongoing competition at the tournament.
