Raphael Collignon enters this US Open first-round matchup as the clear favorite due to his ATP ranking of No. 38, recent deep runs including a Gstaad final, and established professional experience on the tour. The 24-year-old Belgian has compiled a strong overall record and multiple Challenger titles, though his hard-court results in the lead-up have been mixed with early exits in Toronto, Cincinnati, and Winston-Salem. Sebastian Gorzny, a 22-year-old American ranked No. 760 and recent college standout at Texas, earned his main-draw wildcard via the USTA playoff but lacks ATP-level seasoning and faces a steep challenge on outdoor hard courts in his Grand Slam debut. No prior head-to-head exists between the pair.
