**Mary Stoiana holds a clear edge entering the US Open qualifying second round against Katie Swan on outdoor hard courts.** Ranked No. 122 with a career-high points total, the 23-year-old American and 17th seed has posted strong recent hard-court results, including three wins at the Cincinnati Open (qualifying and main draw) and victories in Toronto and Newport qualifiers. Stoiana defeated Harmony Tan in straight sets in her Q1 match. Swan, ranked No. 206, arrives after a grass-heavy schedule highlighted by a Wimbledon first-round win but a second-round loss to Madison Keys; she also dispatched Katrina Scott convincingly in Q1. The pair has no prior head-to-head record. Stoiana’s higher ranking, North American hard-court momentum, and home-soil scheduling create the primary separation in trader assessments, though both players have shown the ability to win matches in straight sets on this surface.
