Arthur Fils enters this US Open first-round hard-court matchup as the heavy favorite against Stefanos Tsitsipas, buoyed by a perfect 5-0 head-to-head record that includes a lopsided 6-0, 6-1 victory in Miami earlier in 2026. Fils arrives in strong form after claiming the Cincinnati Masters 1000 title and posting a dominant 2026 win rate, while his power baseline game and athleticism suit the quick Flushing Meadows conditions. Tsitsipas, now ranked around No. 53 after a prolonged slump, has shown modest recent improvement with a Gstaad title and coaching input from Patrick Mouratoglou, but remains well below his former top-three level following back issues and multiple staff changes. The draw places Fils on a potentially demanding path, yet his edge in ranking, recent results, and matchup history shapes the current market consensus.
