US Open 2026: Coco Gauff shows rejuvenated serve is a weapon in win over Zeynep Sonmez

Coco Gauff, 22, began her 2026 US Open campaign with a win over Zeynep Sonmez, showcasing a dramatically improved serve that had plagued her at the same tournament in 2025. Last year, Gauff's serving struggles were so severe she was photographed practicing in the rain and crying on court. The two-time Grand Slam champion appears to have resolved the issue ahead of this year's tournament.
