Frances Tiafoe enters this US Open second-round match as the clear market favorite at roughly 76-80% implied probability, reflecting his No. 12 ranking, two prior semifinals at Flushing Meadows, and consistent hard-court results that include a Cincinnati final appearance. The 28-year-old American survived a five-set battle against Martin Damm that extended past midnight, while 20-year-old qualifier Rei Sakamoto also prevailed in five sets over Aleksandar Vukic after navigating qualifying wins that included a retirement of Kei Nishikori. Sakamoto, ranked around 157 with limited main-draw experience, brings a powerful serve and recent momentum but faces a steep gap in ATP-level seasoning and home-crowd support on Louis Armstrong Stadium. Both players carry fatigue from extended openers on outdoor hard courts, though Tiafoe’s deeper Grand Slam pedigree and physical recovery routines position him strongly to advance.
