Coco Gauff defeats Zeynep Sonmez in first round of US Open

Coco Gauff advanced to the second round of the US Open on Tuesday after securing a 6-3, 6-4 victory over Zeynep Sonmez at Flushing Meadows. The fourth-seeded American utilized a revitalized service game to navigate the match, including a crucial hold when trailing in the second set. Gauff worked with biomechanics expert Gavin MacMillan over the past year to adjust her technique, focusing on toss consistency and wrist positioning. While the 22-year-old still recorded double faults, she relied on high-velocity serves to maintain control throughout the opening round. Gauff will face either Paula Badosa or Daria Kastakina in her next match. This win marks a significant shift from her 2023 tournament run, where serving difficulties hampered her performance.
