Karen Khachanov vs Alexander Blockx Prediction U.S. Open - New York · Sep 9, 2026

Analysis

Khachanov arrives in the New York quarter-final without having conceded a set in the results provided, closing out Roman Andres Burruchaga and then Benjamin Bonzi 3-0 on 5 September. That is exactly the profile that travels well over best-of-five: heavy first-strike hitting, a serve that shortens points, and the physical base to stay in a fourth-hour rally. Blockx, though, is the more dangerous form pick of the two, having taken out Francisco Cerundolo 3-1 on 6 September and Flavio Cobolli 3-1 the day before, both times recovering after dropping a set. That resilience is why this rates as a competitive match rather than a routine one, and why at least one set for the Belgian looks likely. Experience over five sets on a big-stadium court is the separator, so Khachanov is the marginal favourite without being a lock.
