The absence of world No. 1 Jannik Sinner with a right knee injury, combined with Carlos Alcaraz’s return from a four-month wrist layoff as defending champion, has opened the 2026 US Open men’s draw significantly ahead of the August 30 main draw start. Alexander Zverev assumes the top seed, while Alcaraz enters as the consensus title favorite on hard courts despite limited recent match play. Qualifying rounds underway at Flushing Meadows will fill the bottom half of the bracket, where lower-ranked players and emerging talents face a path to the round of 16 that depends on favorable early matchups, physical freshness after the summer hard-court swing, and avoidance of early clashes with established seeds such as Novak Djokovic or Ben Shelton. Recent form on outdoor hard courts, official injury reports, and any late withdrawals remain the primary variables that will shape implied probabilities for individual players advancing past the third round.
