Ajla Tomljanovic will be in a familiar setting at Flushing Meadows when she faces world No.3 Coco Gauff.
New York, USA, 24 August 2025 | Jackson Mansell
Ajla Tomljanovic knows what it is like to defeat a big-name American in enemy territory.
In 2022, Tomljanovic quashed Serena Williams’ hopes of a fairytale end to her career. Tomljanovic upset the 23-time Grand Slam champion in what would be her final match in front of a packed Arthur Ashe Stadium.

Tomljanovic’s first-round match at US Open 2025 poses a similarly daunting scenario in the same enemy territory against a much-loved American, also likely to be played in front of a packed house at Arthur Ashe Stadium.
The world No.84 faces third seed and former US Open champion Coco Gauff. The American No.1 dropped just three games in their only prior meeting in the opening round of the Paris Olympics last year.
Tomljanovic hopes to maintain her first-round form at Flushing Meadows. The 32-year-old has only lost one opening-round match at the tournament since 2017, having reached the second round the past four years.
Kimberly Birrell will also take on a local opponent in No.8 seed Amanda Anisimova. The Queenslander holds a 1-1 record against Americans ranked in the top 10 this season.
Birrell stunned world No.8 Emma Navarro at the Brisbane International in January but succumbed to world No.4 Jessica Pegula in Cincinnati this month.
An all-Australian encounter headlines men’s singles action when No.8 seed Alex de Minaur faces world No.79 Chris O’Connell for the first time. De Minaur reached the fourth of his five Grand Slam quarterfinals at last year’s US Open – the only Slam at which he has passed the fourth round twice.
