Blockx vs Khachanov Analysis
Blockx is enjoying the best season of his young career, and his remarkable run in New York has taken his breakthrough to another level. The 21-year-old Belgian has compiled a 37-16 record across all levels in 2026 and entered the US Open ranked inside the top 40 after starting the year well outside that territory. Blockx has been particularly effective on hard courts, and he's now reached his first career Grand Slam quarterfinal. Most impressively, he hasn't simply benefited from a favorable draw. The Belgian has already knocked off two seeded opponents at Flushing Meadows and has shown the ability to maintain an aggressive level over best-of-five matches.
Blockx cruised through his opening match against Marcelo Tomás Barrios Vera in straight sets before beating Marco Trungelliti in four. His biggest statement came in the third round against No. 5 seed Flavio Cobolli. After dropping the opening set in a tiebreak, Blockx responded by winning the next three, including a dominant 6-0 third set. He then backed up that upset by beating No. 24 Francisco Cerundolo 6-3, 4-6, 7-5, 7-5 in the fourth round. The Belgian has dropped only three sets across four matches and has looked increasingly comfortable on the big stage. Khachanov represents another step up in terms of Grand Slam experience, but Blockx has already proven he can handle top-notch opponents.
Khachanov arrived in New York in very different form. The veteran had lost his opening match at each of his three US Open tune-up tournaments and entered the final Major of ‘26 ranked around No. 50 on the Tour. However, the former top-10 player has rediscovered his best tennis when it matters. Khachanov is a proven performer at majors, having previously reached the semifinals of the US Open in 2022, and his run this summer marks his seventh career Grand Slam quarterfinal. His biggest victory came in the second round, when he recovered from losing the opening set to eliminate Canadian star Felix Auger-Aliassime in four sets.
Since then, Khachanov has continued to build momentum. He comfortably dispatched Benjamin Bonzi 6-3, 6-2, 6-4 in the third round before surviving his toughest test against No. 14 seed Learner Tien. Khachanov trailed two sets to one but bounced back with authority, winning the fourth set 6-1 before taking the decider 6-4 in a match lasting nearly four hours. His powerful serve and heavy baseline game have been clicking in New York, while his ability to battle through adversity against Tien showed why his experience could be a major advantage against Blockx.
Alexander Blockx vs Karen Khachanov Picks
Blockx is playing phenomenal tennis, but Khachanov tends to find his best in these Majors, specifically the US Open. He’s performed on this stage before, and I’ll take the Russsian to end the Belgian’s Cinderella run. His experience will prove to be key.
Pick: Karen Khachanov -182 /TonyBet
