It wasn't easy, but Coco Gauff survived a three-set thriller against Ajla Tomljanovic this Tuesday night at the US Open. Before the US Open officially started on Sunday, Gauff parted ways with coaches Matt Daly and J.

In her first match since a major shakeup, Gauff trailed 1-3 early on before taking five of the next six games and sealing the opener. In the second set, the American twice blew a break - and she paid the price for that - as Tomljanovic dominated the tie-break to send the match into a decider.

On a night when Coco Gauff ground out a near three-hour win over Ajla Tomljanovic and Naomi Osaka eased past Greet Minnen, two of the game’s multi-major champions moved in tandem into the US Open’s second round.

Former champion Coco Gauff launched her US Open campaign with a 6-4, 6-7(2), 7-5 win over unseeded Ajla Tomljanovic in the first round on Tuesday, as the American navigated a big test following a late coaching shake-up ahead of the year's final Grand Slam.

Day three of the US Open featured thrilling matches and impressive comebacks. Coco Gauff overcame Ajla Tomljanovic, Stefanos Tsitsipas passed Muller, and Francisco Cerundolo staged a stunning comeback.

Ajla Tomljanovic will be in a familiar setting at Flushing Meadows when she faces world No.3 Coco Gauff. Ajla Tomljanovic knows what it is like to defeat a big-name American in enemy territory.
