The US Open will become a 15-day tournament in 2025, beginning on a weekend for the first time in the Open era.

This year’s main draw at Flushing Meadows will start on Sunday, 24 August and end on Sunday, 7 September.

It becomes the latest Grand Slam to announce a Sunday start. The Australian Open expanded to a 15-day tournament in 2024, after the French Open took that decision in 2006.

The tournament estimates the expansion will allow access for an additional 70,000 spectators.

That leaves Wimbledon as the only remaining Slam event to retain the traditional Monday start.
