Coco Gauff enters the first-round US Open matchup against Zeynep Sonmez as the clear favorite, backed by her No. 4 ranking, 2023 title at Flushing Meadows, and strong 2026 hard-court form that includes a Cincinnati Open victory. The 22-year-old American holds a 40-13 record this season and has yet to drop a set in her two prior meetings against lower-ranked opponents in recent tune-ups. Sonmez, ranked No. 52 with a 28-19 mark, brings solid recent results including an Australian Open third-round run but has never faced Gauff and owns limited success beyond the second round at majors. The pair had no prior head-to-head and learned of the draw while preparing to practice together. Trader pricing reflects Gauff’s experience edge and surface comfort on outdoor hard courts, with Sonmez viewed as an underdog despite her steady 2026 progress.
