World No. 1 Sinner Wins US Open First Round

World number one and defending US Open champion Jannik Sinner began his title defense with a dominant straight-sets victory over Czech player Vit Kopriva, winning 6-1, 6-1, 6-2 at Arthur Ashe Stadium. Sinner, who recently recovered from illness that caused him to retire in the Cincinnati Open final, displayed strong form and broke Kopriva seven times, advancing to face either Alexei Popyrin or Emil Ruusuvuori next. The 24-year-old Italian has won three of the past four Grand Slams and is aiming to become the first man since Roger Federer to successfully defend the US Open title. Despite a doping suspension earlier this year for testing positive for clostebol, Sinner's performance at Flushing Meadows has been widely praised, and the crowd showed strong support. Reflecting on his comeback, Sinner expressed happiness about his health and readiness, emphasizing the unique significance of the tournament. His victory marks his 22nd consecutive hard-court Grand Slam match win, underscoring his current dominance in men's tennis.
