Coco Gauff survives while revamping her serve at same time

If the most fascinating fight in men’s tennis is Jannik Sinner vs. Carlos Alcaraz, in the women’s game, it’s Coco Gauff against her serve.

It’s only the most important part of a player’s game, like an NBA star’s jumper or a pitcher’s command. And Gauff picked the eve of her home Slam to rejigger her coaching staff and remake her serve.

No pressure, then.

Under the lights at Arthur Ashe Stadium, Gauff served just well enough to gut out a 6-4, 6-7 (2), 7-5 U.S. Open first-round win over Ajla Tomljanovic.
