Felix Auger-Aliassime upsets Alexander Zverev, pushing subsequent US Open match to 11:28 p.m. start

NEW YORK (AP) — The final match Saturday at the U.S. Open got underway closer to midnight than expected, when Maria Sakkari and Beatriz Haddad Maia took the court at Louis Armstrong Stadium at 11:28 p.m.

They were delayed by a nearly four-hour men's match that ended with Felix Auger-Aliassime eliminating third-seeded Alexander Zverev in four sets.

The American Grand Slam instituted a policy last year that a tournament referee can move any match that hasn't gone on by 11:15 p.m. to another court. A U.S. Tennis Association spokesperson said the decision had been made after the fourth set of Auger-Aliassime versus Zverev that Sakkari and Haddad Maia would play either on Armstrong as scheduled or another court.

Had Auger-Aliassime and Zverev gone into a fifth set, the Sakkari-Haddad Maia match would have been moved elsewhere, the spokesperson said.

This was the seventh-latest start in Flushing Meadows, and it came a year to the day of the record-setter when Aryna Sabalenka and Ekaterina Alexandrova's night-session match began at 12:07 a.m. — technically on Aug. 31. It was not the latest U.S. Open start for Haddad Maia, who began a match against Bianca Andreescu at 11:38 p.m. in 2022.

Late-night matches and scheduling in majors has become a hot debate in the sport, notably also at the French Open and Australian Open. Wimbledon has an 11 p.m. curfew.

The final men's match of the day, Tommy Paul against Alexander Bublik, was only in the second set in Arthur Ashe Stadium when Sakkari and Haddad Maia started. Iga Swiatek rallied from down 5-1 in the first set to beat Anna Kalinskaya to begin the night session on Ashe.

Paul played a post-midnight marathon match Thursday into Friday in the second round, defeating Nuno Borges in 4 hours, 25 minutes concluding at 1:46
