**US Open First Round Concludes with Sinner, Osaka, and Gauff Headlining Tuesday’s Action**
**NEW YORK, NY** – The final day of first-round action at the US Open promises high stakes and compelling matchups as Jannik Sinner, Naomi Osaka, and Coco Gauff take center stage.
Jannik Sinner, currently ranked No. 1, faces Vit Kopriva, with the top spot on the ATP rankings at stake. A strong performance is crucial for the Italian, who boasts an impressive 21-match hardcourt winning streak at the majors.
Naomi Osaka, seeking to continue her resurgence after reaching the final in Montreal, squares off against Greet Minnen. The four-time major champion, now working with coach Tomasz Wiktorowski, is hoping to translate her recent success into a deep run at her favorite major. She had called him a walking tennis encyclopedia.
Coco Gauff, the 2023 US Open champion, will face Ajla Tomljanovic. The 20-year-old American is also debuting her newly revised serve with new biomechanics coach Gavin MacMillan. Gauff won their previous meeting at the Olympics, but Tomljanovic’s hardcourt prowess could pose a challenge if Gauff isn’t aggressive enough.
Tennis fans eagerly await these matches, which promise excitement and potential upsets as the tournament progresses.
