Frances Tiafoe, the No. 11 seed ranked around No. 12, enters the US Open second round after rallying from two sets to one down in a five-set win over fellow American Martin Damm on August 31, extending his streak of consecutive major first-round victories. The 28-year-old has deep experience at Flushing Meadows, including prior semifinal appearances, and strong recent hard-court form highlighted by a Cincinnati final run. Rei Sakamoto, the 20-year-old Japanese qualifier ranked No. 157, advanced via three qualifying wins and a five-set first-round victory over Aleksandar Vukic, showcasing his 6'4" frame, powerful serve, and improving ATP-level results on hard courts. As a rising talent with Challenger titles and junior Grand Slam success, Sakamoto represents an underdog with realistic upset potential in a matchup likely shaped by experience, stamina, and home-crowd dynamics.

If set 3 begins but is not completed, this market will resolve 50-50, unless the outcome has already been unconditionally determined based on completed play. An outcome is considered determined if it would have been guaranteed had the set been played to completion using the minimum number of additional games required. For example, for a line of 9.5, if play stops with set 3 at 5-4, completing the set would have required at least 1 additional game, resulting in at least 10 games played, so "Over" would resolve as the winning outcome.
If the match ends before set 3 is reached, this market will resolve 50-50. If the match is canceled before play begins, or play has not begun by September 16, 2026, 11:59 PM ET (14 days after the scheduled start), this market will also resolve 50-50.

Resolution will be based on official Grand Slam results.Frances Tiafoe, the No. 11 seed ranked around No. 12, enters the US Open second round after rallying from two sets to one down in a five-set win over fellow American Martin Damm on August 31, extending his streak of consecutive major first-round victories. The 28-year-old has deep experience at Flushing Meadows, including prior semifinal appearances, and strong recent hard-court form highlighted by a Cincinnati final run. Rei Sakamoto, the 20-year-old Japanese qualifier ranked No. 157, advanced via three qualifying wins and a five-set first-round victory over Aleksandar Vukic, showcasing his 6'4" frame, powerful serve, and improving ATP-level results on hard courts. As a rising talent with Challenger titles and junior Grand Slam success, Sakamoto represents an underdog with realistic upset potential in a matchup likely shaped by experience, stamina, and home-crowd dynamics.
