Second-seeded Alexander Zverev faces qualifier Alexander Blockx in the Mutua Madrid Open semi-finals after both advanced via quarter-final wins on Thursday. The 21-year-old Belgian, ranked No. 69 with a career-high from April 20, has electrified the draw on clay—his first ATP-level wins on the surface—stunning Felix Auger-Aliassime in the third round and upsetting No. 12 Casper Ruud 6-4, 7-6(3) despite no prior Masters 1000 deep runs. Zverev, a two-time former Madrid champion seeking his fourth semi-final here, grinded past Jakub Mensik and Flavio Cobolli (avenging a Munich semi-final loss) amid vague post-match injury concerns. No head-to-head exists, but Zverev's baseline dominance and high-altitude clay experience contrast Blockx's aggressive 6-4 frame and 10-2 clay record this year, shaping a competitive matchup with upset potential.
