Core Match Details
Top-seeded Alexander Zverev defeated Italy’s Lorenzo Sonego 6-4, 3-6, 6-7, 7-5, 6-4 in the opening round of the U.S. Open on September 2, 2026 at Arthur Ashe Stadium. The five-set battle stretched into the early morning, with the New York Post timing the contest at 4 hours 52 minutes and RTE noting a duration of 4 hours 53 minutes. Zverev saved two match points in the fourth set before breaking Sonego to force a deciding fifth set, which he clinched after breaking for a 3-2 lead and holding serve to close the match at 1:55 a.m. local time.
Background & Context
Zverev entered the tournament as the first men’s top seed at a Grand Slam since Jannik Sinner withdrew with a right-knee injury. He had captured his maiden major title at the French Open earlier in June and reached the Wimbledon final, but his hard-court form had been uneven, with a first-round loss in Canada and a third-round exit in Cincinnati. Historically, a men’s No. 1 seed had not fallen in a first-round Grand Slam match since Lleyton Hewitt’s loss to Ivo Karlovic at Wimbledon in 2003, and the U.S. Open had not seen a top-seed defeat in the opening round since Stefan Edberg’s loss to Alexander Volkov in 1990.

Why It Matters
By surviving, Zverev prevented the first top-seed first-round exit at a Grand Slam in 23 years, preserving the tournament’s seeding structure and keeping the path open for American men amid a 23-year U.S. Open men’s-title drought. His victory also maintained his momentum after a patchy hard-court season, positioning him as a leading contender for a second major title in the calendar year—a feat achieved by only a handful of Open-Era players.
