When Alexander Blockx woke up on Friday before the Mutua Madrid Open, he wasn’t sure if he would need to fight to qualify for the ATP Masters 1000 event. But a series of late withdrawals led to the Belgian taking his place in the main tournament, and he never looked back, advancing to the semi-finals of the ATP Masters 1000 at Caja Magica.
On Friday, the 21-year-old from Antwerp will face his toughest test yet in two-time Madrid champion and second seed Alexander Zverev. Will one of the season’s breakout stars continue his incredible run, or will Zverev hold on to their intergenerational summit to make his first final of the season?
Blockx will need to fill the experience gap with one of the most consistent players on the ATP Tour. The 2025 Next Gen ATP Finals contender began the month of April without a main-draw appearance at an ATP Tour clay-court event to his name, and this will be Zverev’s 11th Masters 1000 semi-final at the top.
“I have never [had] a lot of confidence in clay over the past few years. But I think I can’t say that anymore with the results I’m doing,” Blockx said after upsetting defending champion Casper Ruud in the quarter-finals. And I think the conditions here are faster than on regular clay, so that helps too. But, yeah, I really like clay now.”
It will be his first Lexus ATP Head2Head meeting against Zverev, who has reached the semifinals in the first four Masters 1000 events of the season, joining Roger Federer, Rafael Nadal and Jannik Sinner as the only men to achieve the feat in the series’ history (since 1990). But the German will take to the court with a lot of respect for his young opponent, who has climbed 34 spots to number 35 in the PIF ATP Live Rankings.
“He’s a young player, a young player. I think he has a good spirit when he’s on the tennis court,” Zverev said. “I enjoy watching him play, I think he is a nice guy and off the court, he is decent and I will enjoy our first meeting.”
[ALSO LIKE]There is history on Zverev’s side. The seven-time Masters 1000 seed is 13-0 against players ranked outside the Top 30 in Madrid according to the Infosys ATP Win/Loss Index, and has reached the finals of the tournament three times. He is 0-5 in the semifinals this season, but has more career hits in Madrid (29) than Blockx has played in tour-level games overall (28).
Like Zverev, Blockx can use the big game and dominate, but he’s also comfortable gathering behind the baseline. The big question will be whether he can make his experienced opponent uncomfortable under pressure.
“I never thought I would get this far,” said Blockx, who at 21 years and 25 days would become the sixth-youngest player in the tournament’s history behind Carlos Alcaraz, Nadal, Stefanos Tsitsipas, Zverev and Andy Murray. “But once you’re confident and feel your game, a lot happens.”
Blockx will be hoping that confidence can help him achieve another success in the tournament where he has already knocked out third seed Felix Auger-Aliassime. Their match will start before 8pm local time.
