Madrid Open 2026 Day Four Summary

Day four at the Mutua Madrid Open was another fairly typical early round day, with most of the top seeds advancing, although some notable upsets and dramatic moments kept things interesting.

The standout match was Terence Atmane’s gritty two-tiebreak victory over 30th seed Ugo Humbert, with Atmane fighting through severe cramping to somehow close out the victory.

Elsewhere, qualifier Alexander Blockx upset Brandon Nakashima, young Norwegian Nicolai Budkov Kjær beat Denis Shapovalov, and Stefanos Tsitsipas looked much sharper in a solid straight sets victory over eighth-seeded Alexander Bublik.

Second seed Alexander Zverev had a mid-match lapse but recovered to beat Mariano Navone, while defending champion Casper Ruud cruised past Jaume Munar.

Here are the notable results from Day 4:

Summary of the match

Terence Atmane def. (30) Hugo Humbert 7-6(3) 7-6(5)

This was the most compelling match of the day. Atmane pulled off a brutal upset over his fellow Frenchman in two tiebreaks. He served out the match at 5-3 in the second set but suddenly suffered severe convulsions, collapsing to the ground in pain and looking barely able to move.

Somehow he hung on and won the tiebreak from 2-5 down despite barely being able to serve or run. Humbert contributed heavily to his own downfall with plenty of unforced errors (49 in the match) and a poor serve day (only 53% first serve in).

Alexander Blockx def. (28) Brandon Nakashima 3-6 6-3 6-4

The 20-year-old Belgian qualifier came back from a set down to upset the seeded American in a competitive three-setter. He now gets a tough third-round assignment against Felix Auger-Aliassime.

Nicolai Budkov Kjær (Q) def. (31) Denis Shapovalov 6-2 6-1

A very one-sided blow by the young Norwegian qualifier. Shapovalov had no answers as Budkov Kjær cruised through in straight sets in just 53 minutes.

Adolfo Daniel Vallejo (Q) def. (17) Learner Tien 6-4 6-3

The Paraguayan qualifier kept his strong Madrid run going with another clean sweep in straight sets.

(2) Alexander Zverev def. Mariano Navone 6-1 3-6 6-3

Zverev looked dominant in the first and third sets but completely lost focus in the second, losing 3-6. He admitted afterwards that he “completely lost focus” but was pleased with the level of the sets he won. He will face Atmane next.

With Alcaraz missing, Zverev should be looking to capitalise.

(12) Casper Ruud def. Jaume Munar 6-0 6-1

The defending champion was brutal, dropping just a handful of games against the home player, who appeared physically struggling as he came up with virtually no serve or forehand. So hard to tell if Ruud is over his calf injury, but quick games like this can only help.

Stefanos Tsitsipas def. (8) Alexander Bublik 6-2 7-5

This was a strong, confident performance from Tsitsipas and easily one of his best wins in a difficult 2026 season so far.

After needing three tough sets to scrape past lucky loser Patrick Kypson in the first round (where he was two points from defeat), the Greek looked much sharper against the dangerous eighth seed.

He dominated the first set 6-2 with aggressive baseline play and solid return, then held his nerve in the second set to finish 7-5 in just 1 hour and 13 minutes.

Bublik, who can be unpredictable on any surface, never quite found his rhythm or his big serving weapons on the bouncy Madrid clay.

I was in two minds about what to expect from this one; part of me thought Tsitsipas might have gained some momentum after his Kypson win, the other thought he would struggle to win enough return points.

The former proved to be correct, and this victory should give Tsitsipas a much-needed confidence boost
