Zverev vs. Blockx Head-to-Head Record
This match marks the first-ever meeting between Zverev and Blockx on the ATP Tour. Blockx’s impressive run in Madrid includes victories over several top players. The Belgian showcased great composure to defeat Ruud, hitting 19 winners, including a stunning back-spin drop shot.
Adding to his impressive win over Ruud, Blockx’s consistent baseline play has been another key feature of his strong showing in Madrid. This consistency helped him see off not only the defending champion but also Auger-Aliassime, as well as clay-court specialists Francisco Cerúndolo and Cristian GarÃn.
Meanwhile, Zverev has had to work hard to reach the semifinals. He needed three sets to overcome Jakub MenÅ¡Ãk and Mariano Navone and was fortunate to beat Terence Atmane in straight sets after briefly losing focus in the second.
Despite those challenges, Zverev delivered a near-perfect performance in the quarterfinals, firing 12 aces and 23 winners en route to a dominant 6-1, 6-4 win over Cobolli.
Prediction and Pick for Zverev vs. Blockx
Zverev’s big-match experience could hold the key in this semifinal against a player who has never reached this stage at an ATP tournament.
Both players have demonstrated elite serving in Madrid: Zverev has fired 34 aces, while Blockx has had his serve broken just three times. As a result, the key to this match could well rest on which player can manage to get the upper hand while returning.
Moreover, the world No. 3 is also 3-0 in semifinals at the Madrid Open, which will serve as a confidence boost for him, even if he hasn’t yet made a final this year.
Still, Blockx certainly shouldn’t be taken lightly in this semifinal. He has consistently outperformed expectations in Madrid and has the tools to defeat Zverev.
