Arthur Fils enters this US Open first-round matchup on outdoor hard courts as the clear favorite, buoyed by a career-best No. 11 ranking after capturing his maiden Masters 1000 title in Cincinnati with dominant wins over top-10 players. The 22-year-old Frenchman leads the head-to-head 5-0, including a 6-0, 6-1 demolition of Tsitsipas on hard courts in Miami earlier this year. Tsitsipas, now ranked No. 53 after a prolonged slump, has posted mixed hard-court results this summer with early exits in Montreal and Cincinnati, though he recently claimed a clay-court title in Gstaad and arrives motivated under new coaching input. Fils’ superior recent form, serving consistency, and athletic baseline game shape trader consensus around his strong implied probability.
