US Open: Khachanov vs Blockx Odds, Picks & How to Watch
Karen Khachanov has already survived one five-set examination at this US Open. On Wednesday, September 9, the former New York semifinalist faces a different kind of test: Alexander Blockx, a fearless 21-year-old contesting his first Grand Slam quarterfinal. Blockx has served through pressure, beaten two seeds and carried a painful rib through four sets against Francisco Cerundolo. Khachanov owns the heavier résumé and deeper five-set toolkit, but his 52-game escape against Learner Tien left miles in his legs. This matchup looks tighter, longer, and far more serve-driven than the rankings initially suggest.

Expert Picks: Karen Khachanov vs Alexander Blockx
Best Bet: Khachanov Over 20.5 Total Games
Khachanov has cleared 20 games in every match that lasted beyond three sets, collecting 24 against Auger-Aliassime and 29 against Tien. Blockx has protected serve well enough to extend sets, while Khachanov’s return may require patience. Twenty-one games can land in four sets and remains reachable even if the favorite loses.
Pick 2: Karen Khachanov -1.5 Sets
The line asks Khachanov to win by at least two sets, most likely 3-0 or 3-1. That becomes attractive if Blockx’s ribs tighten during a long match. Khachanov has reached major semifinals and just finished a five-set recovery; his experience, return pressure, and physical durability should separate them after the opening stages.

Pick 3: First Set Over 10.5 Games
Both players may open behind serve before the physical questions become decisive. Blockx has won 12 of 15 sets in New York, and Khachanov has dropped only three, so an immediate runaway looks unlikely. A 7-5 or 7-6 opener fits two aggressive first-strike players who should need time to expose each other’s movement.
Pick 4: A Tiebreak to Be Played — Yes
Two of Khachanov’s four US Open matches have produced a tiebreak, while Blockx played one against Cobolli and three against Zverev at Wimbledon. Neither returner consistently dominates first serves. With both men comfortable striking early and shortening points, one set reaching 6-6 is a stronger angle than chasing a routine favorite win.

Final Prediction: Does Blockx Have One More Upset in Him?
Blockx has earned his place in this quarterfinal. His serve is dangerous, his forehand carries genuine weight, and his composure has been remarkable for a player navigating his first major breakthrough.
The rib issue makes the second half of the match difficult to trust. Khachanov does not need to overpower him immediately. The veteran can work through tight opening sets, make Blockx serve repeatedly under scoreboard pressure, and gradually turn the contest into a physical examination.
Expect at least one tiebreak and several service games with very little separation. Blockx should take a set, but Khachanov’s experience and durability give him the clearer route once the match moves beyond two hours.
