Flavio Cobolli enters the US Open third-round matchup as the clear favorite, holding the No. 6 ranking and superior recent results on hard courts against the rising Belgian. The 24-year-old Italian reached the Cincinnati semifinals in August before falling to Arthur Fils, building on a strong 2026 season that includes an ATP title and a Roland Garros final. Alexander Blockx, ranked No. 34 at age 21, arrives with momentum after straight-set wins in the first two US Open rounds and a career-high ranking achieved earlier in the year. Their head-to-head stands at 1-1, with Blockx claiming a straight-sets clay victory in Monte Carlo and Cobolli prevailing in a tight three-set hard-court contest at Cincinnati. Outdoor hard-court conditions, best-of-five format, and Cobolli’s greater experience against top competition shape the matchup dynamics.
