Defending Champ Sinner Advances US Open Quarters

World No. 1 and defending US Open champion Jannik Sinner dominated Alexander Bublik in a commanding 6-1, 6-1, 6-1 victory to advance to the quarter-finals at the 2025 US Open. Sinner completed the match in just 81 minutes, breaking Bublik's impressive 55-game service streak and avenging a previous loss to the Kazakh player earlier in the year. Playing his first night session of the tournament under the Arthur Ashe Stadium lights, Sinner praised the unique atmosphere and expressed feeling privileged to compete on such a stage. Despite Bublik's attempts to disrupt Sinner with drop shots and underarm serves, Sinner's relentless offense and early breaks set the tone for a one-sided contest. Bublik acknowledged Sinner's exceptional play, even calling him "like an AI-generated player," and showed sportsmanship by embracing Sinner after the match. Sinner will face fellow Italian Lorenzo Musetti in the quarter-finals as he pursues his third Grand Slam title of the season.
