On August 26, 2025, Coco Gauff, the world number 3, steps onto the Arthur Ashe Stadium in New York to face Australian Ajla Tomljanovic in the first round of the US Open 2025, one of the most prestigious tennis tournaments globally. The 21-year-old American, who won the tournament in 2023 and Roland Garros in 2024, is focusing solely on singles after opting out of mixed doubles to sharpen her game. Tomljanovic, known for her 2022 upset against Serena Williams on the same court, brings experience and unpredictability. The match, scheduled for 7 p.m. local time, has fans packing the stands, eager to see if Gauff can handle the pressure of playing at home or if Tomljanovic will pull off another surprise. Gauff’s recent season, marked by triumphs and setbacks, contrasts with Tomljanovic’s struggle to regain form, setting the stage for a gripping encounter.
Gauff’s choice to skip mixed doubles underscores her commitment to chasing a second US Open title. Despite her Roland Garros victory, her 2025 season has been uneven, with a first-round exit at Wimbledon and 16 double faults in a loss to Jasmine Paolini in Cincinnati. Tomljanovic, ranked 79th, has had a tough year with 20 wins and 19 losses, hampered by past injuries. Yet, her ability to shine on big stages makes her a dangerous opponent.
Key match details:
Gauff defeated Tomljanovic 6-3, 6-0 at the 2024 Paris Olympics.
Tomljanovic reached the US Open quarterfinals in 2022.
The match is set at Arthur Ashe Stadium, the tournament’s largest court.
Gauff is the third seed, while Tomljanovic is unseeded.
Gauff’s preparation and pressure
Coco Gauff enters the US Open 2025 with high expectations, aiming to reclaim the title she won in 2023 as the youngest champion since Serena Williams. Her season highlights include defeating Aryna Sabalenka at Roland Garros, but inconsistencies, particularly with her serve, have been a challenge. To address this, Gauff enlisted biomechanics expert Gavin MacMillan, who previously helped Sabalenka refine her serve. The hope is that MacMillan’s guidance will stabilize Gauff’s performance in New York, where she faces intense scrutiny as a home favorite.
Tomljanovic, meanwhile, has struggled in 2025, reaching only two semifinals in smaller tournaments like Austin and Rabat. Her 64% service game win rate reflects resilience, but early exits in Cincinnati and Monterrey highlight her inconsistency. Still, her 2022 victory over Serena Williams at Arthur Ashe proves she can upset top players on big stages. Her game plan will likely focus on extending rallies to exploit Gauff’s occasional errors.
Head-to-head and tactical approach
The only prior meeting between Gauff and Tomljanovic was at the 2024 Paris Olympics, where Gauff dominated 6-3, 6-0. This gives her a mental edge, but Tomljanovic’s ability to grind out points could test Gauff’s patience, especially if her serve falters. Gauff’s aggressive baseline game and speed contrast with Tomljanovic’s steady, defensive style, promising a clash of approaches.
Factors that could shape the match:
Gauff’s serve: Reducing double faults is critical for her control.
Tomljanovic’s endurance: Her long rallies could wear Gauff down.
Crowd support: The New York fans will heavily back Gauff.
Physical condition: Tomljanovic’s past injuries may impact her stamina.
Gauff will aim to dictate play with powerful groundstrokes, while Tomljanovic will rely on consistency and tactical variety. The mental battle is key, with Gauff under pressure to perform at home and Tomljanovic playing with the freedom of an underdog.

Significance of the matchup
The US Open 2025 is a pivotal moment for both players. For Gauff, a strong start is crucial to build momentum toward potential clashes with Iga Swiatek or Aryna Sabalenka in later rounds. Her 17-5 record at the US Open, with just one first-round loss, underscores her comfort in New York. Tomljanovic, who has reached the second round in the last four US Opens, aims to upset the odds and reignite her career.
The match carries extra weight due to Tomljanovic’s history at Arthur Ashe, where she ended Serena Williams’ career in 2022. For Gauff, often seen as Serena’s successor, facing this opponent adds an emotional layer. A victory would signal Gauff’s readiness to lead American tennis into the future.
