Top seed Alexander Zverev survives near five-hour marathon at US Open

Top seed Alexander Zverev survived a grueling first-round match at the US Open, defeating Italy's Lorenzo Sonego 6-4, 3-6, 6-7 (7), 7-5, 6-4 in nearly five hours, with the match concluding in the early hours of Wednesday morning. Zverev avoided becoming the first men's No. 1 seed to lose in the first round of a grand slam since Ivo Karlovic defeated Lleyton Hewitt at Wimbledon in 2003. The German struggled to convert break opportunities throughout the match before ultimately prevailing in five sets.
