Coco Gauff enters this US Open first-round matchup as the No. 4 seed and 2023 champion with a 40-13 record, fresh off a dominant Cincinnati title run that included straight-sets victories over top competition and highlighted improved serve consistency alongside her elite court coverage. Zeynep Sonmez, ranked No. 52 after a career-high of No. 48, brings a 28-19 season mark with three quarterfinals but has shown inconsistency on hard courts recently, including early exits in Toronto and Cincinnati. The pair has no prior head-to-head history, though Gauff's hard-court dominance (194-76 career) and experience at Flushing Meadows create a significant edge over the Turkish player's solid but less proven Grand Slam results, which peak at third rounds. Traders view Gauff's momentum and physical advantages as decisive on the fast hard-court surface.
