Frances Tiafoe enters as the clear market favorite at roughly 80% implied probability, reflecting his No. 12 ranking, three prior US Open quarterfinals, and stronger 2026 hard-court results that include a Cincinnati final. The 28-year-old American rallied from two sets to one down in his five-set first-round win over Martin Damm, preserving a long streak of major opening-round victories. Rei Sakamoto, the 20-year-old Japanese qualifier ranked No. 157, arrives after a five-set upset of Aleksandar Vukic that featured 38 aces and demonstrated improved physical endurance following his Australian Open main-draw debut. The hard-court surface and potential fatigue from consecutive long matches represent the key variables that could influence the outcome on Louis Armstrong Stadium.
