When the lights stay on at Flushing Meadows long after the Manhattan commuters have settled in, the US Open leans into its reputation as the sport's most raucous stage. But as the clock ticks past 3:00 a.m., that reputation is beginning to look less like a branding triumph and more like a physiological crisis for the athletes tasked with performing under them.
The absurdity reached a breaking point on Wednesday when American eighth seed Ben Shelton completed his last-eight victory over Carlos Alcaraz at 3:34 a.m.—the latest finish in US Open history. For Shelton, the victory was a triumph of will; for the tournament, it was a signal of a systemic scheduling instability that is leaving even the world's elite struggling to function.
The Sleep Gap and the Competitive Imbalance
The current schedule is creating a stark disparity in recovery windows, turning matches into tests of circadian rhythm rather than just tactical execution. The discrepancy between players is no longer marginal; it is transformative.
- The Exhausted: Alexander Zverev has seen three of his last five matches conclude after 1:00 a.m. He reported going to bed as late as 6:45 a.m. in a single week, describing the experience as "playing the Australian Open in New York."
- The Fresh: Conversely, unseeded Karen Khachanov has yet to step on court beyond midnight. Similarly, Frances Tiafoe wrapped up his quarter-final at approximately 7:00 p.m. on Tuesday, providing him with a massive rest advantage heading into his semi-final matchup.
Matt Little, Andy Murray’s long-time strength and conditioning coach, notes that the advantage of an earlier finish is massive. "The advantage of the opponent who has played earlier in the day will be big—they've had that full evening's rest and a good night's sleep," Little told BBC Sport. He warned that even a single night of poor sleep can create a "knock-on effect" for the days that follow.
A Regulatory Loophole
While the tennis world has seen attempts to curb these late-night marathons, a significant regulatory gap remains. In early 2024, the ATP and WTA implemented rules preventing tour matches (those played in a best-of-three format) from starting after 23:00. However, these protections do not extend to the Grand Slams, where the best-of-five set format remains the standard.
This lack of oversight has allowed matches to drift into the early hours with increasing frequency. Last week, a first-round match between Venus Williams and Sofia Kenin didn't even begin until 12:13 a.m., marking the latest start in the tournament's history. For 18-time Grand Slam champion Martina Navratilova, the trend is inexcusable. "Something has got to give," Navratilova said. "This is not OK and it is not normal."
The Format Debate: Tradition vs. Survival
As match lengths continue to climb, the conversation has shifted from mere scheduling adjustments to the very soul of the game. The most extreme suggestion—reducing men's Grand Slam matches from five sets to three—has gained traction following comments from Tennis Australia CEO Andrew Abdo regarding the Australian Open's potential future.
The proposal has met fierce resistance from those who view the five-set epic as the sport's ultimate test. Tiafoe, for instance, remains a staunch defender of the tradition. "But it's tennis, man. I grew up watching so many incredible five-setters. Novak-Rafa, Federer-Rafa, epic five-setters that go on for hours and hours. That's the history of the game," he argued.
The alternative—starting night sessions earlier—faces its own set of hurdles. Television executives and the practicalities of New York nightlife suggest that many fans are unlikely to arrive at Flushing Meadows before 7:00 p.m., making an earlier start a difficult sell for the tournament's commercial and cultural identity.
Evidence-Led Forecast: Shelton vs. Tiafoe
Tactical Pattern: The semi-final between Ben Shelton and Frances Tiafoe will likely be dictated by physiological recovery rather than just court geometry. Tiafoe enters with a significant rest advantage, having finished his previous match in the evening, while Shelton is managing the aftermath of a 3:34 a.m. finish.
Decisive Matchup: Shelton’s ability to manage his energy levels in the early stages of the match will be critical. If he cannot find rhythm quickly, Tiafoe’s freshness may allow him to dictate play from the baseline before Shelton can settle.
Strongest Counter-case: Shelton has insisted he will pull up "all right" after two days off court, suggesting that the break may be sufficient to mitigate the sleep debt accumulated during his marathon victory over Alcaraz.
What would change the read: Any further delays to the Friday night session start time would disproportionately favor Tiafoe, further tilting the recovery balance in his favor.
