No. 1 Alexander Zverev wins in 5 sets, Coco Gauff starts her quest for a second US Open title - ABC News

World No. 1 seed Alexander Zverev, elevated to the top spot after Jannik Sinner withdrew from the US Open due to a right knee injury, survived a grueling first-round match against Lorenzo Sonego on September 2, 2026, winning 6-4, 3-6, 6-7(7), 7-5, 6-4 in 4 hours and 52 minutes. The French Open champion, competing as the No. 1 seed at a Grand Slam for the first time, narrowly avoided the same fate as No. 4 seed Novak Djokovic, who was eliminated in five sets two nights earlier. Meanwhile, Coco Gauff began her campaign for a second US Open title at the same event in New York.
