Arthur Fils entered the US Open first-round matchup as the clear market favorite, buoyed by his career-high No. 11 ranking, No. 10 seed, and recent Cincinnati Masters 1000 title that capped a six-match win streak on hard courts. The 22-year-old Frenchman also held a 5-0 head-to-head edge over Stefanos Tsitsipas, including a dominant March win in Miami. Tsitsipas, ranked No. 53 and unseeded, countered with greater Grand Slam experience, a July Gstaad title ending a long drought, and improved hard-court form after earlier injury setbacks. Both players brought strong serving and baseline power to the hard-court clash on Louis Armstrong Stadium, with Fils’ recent dominance offset by Tsitsipas’ big-stage pedigree and motivation for a strong New York start.
