Karen Khachanov vs. Alexander Blockx Prediction
Khachanov’s run has been equally impressive, with victories over Felix Auger-Aliassime and Learner Tien providing major tests. He recovered from two sets to one down against Tien to win 7-5, 4-6, 6-7(6), 6-1, 6-4. His command of the final two sets demonstrated that his power and experience remain dangerous deep into a demanding match.
The biggest concern for Blockx is physical. He received treatment during the Cerundolo match and later described pain severe enough that he considered retiring. Finishing in four sets does not establish that the issue has resolved, so the upset case depends on his ability to serve and move effectively. His recent results are encouraging, but his condition cannot be overlooked.
If his body allows him to execute, Blockx has a credible tactical route. His serve can create attacking opportunities, while taking the ball early and changing direction can prevent Khachanov from setting his feet for repeated power exchanges. The Belgian needs to stay assertive without forcing low-percentage winners, particularly against a veteran who has already demonstrated considerable resilience this week.

Khachanov deserves favoritism given his tested form, experience and Blockx’s fitness uncertainty. Still, the Belgian’s wins over Cobolli and Cerundolo show that his momentum is supported by quality tennis. At +130, the appeal is his ability to establish control behind serve and convert the tight passages that decide sets. With effective movement and serving, Blockx has the game to produce another upset and reach the semifinals.
