Alexander Blockx delivered the headline result on Monday at the Madrid Open, stunning world No. 5 Felix Auger Aliassime 7-6(3), 6-3 to claim his first career top 10 victory. The 20-year-old Belgian joins fellow NextGen alumni Rafael Jodar and Dino Prizmic in recording breakthrough top 10 wins this week in Madrid. Alexander Zverev survived a late wobble against Terence Atmane to reach the Madrid fourth round for the ninth consecutive year, while Casper Ruud demolished Alejandro Davidovich Fokina 6-3, 6-1 in his most convincing performance in months. Tuesday's round of 16 promises fireworks with Jannik Sinner chasing a 20th consecutive win, Zverev facing the in-form Jakub Mensik, and Casper Ruud taking on a rejuvenated Stefanos Tsitsipas.
Blockx announces himself with breakthrough victory
The 20-year-old Belgian delivered a composed, all-court performance that announced his arrival among tennis's rising stars. Blockx, who began the season ranked No. 117, has now climbed to No. 53 in the live rankings following his sensational clay-court run. The youngster's serving was exceptional throughout, winning 83% of first serve points while saving the only break point he faced. His pressure-point statistics told the story of a player refusing to be overwhelmed by the occasion - winning 12 of 13 serve pressure points while capitalizing on 2 of 12 return pressure opportunities. The victory continues a remarkable European clay swing for Blockx, who also reached the last 16 in Monte-Carlo and joins fellow Next Gen ATP Finals alumni Rafael Jodar and Dino Prizmic in recording breakthrough Top 10 wins this week in Madrid. For the Canadian, this defeat reflects continuing struggles on clay, as he won just 3 out of 8 matches played in 2025 and despite being 3rd seed there, did not manage to reach out the round of 16, getting defeated by the way less experienced and lower ranked opponent. Blockx is now 12-4 on clay in all the levels of competition during the rolling year and has a reasonable 6-2 record in ATP tour main draw matches, which draws him as a really competent clay court player for the foreseeing future.
Zverev extends Madrid mastery despite late drama
Alexander Zverev maintained his perfect record of reaching Madrid's fourth round, advancing for the ninth consecutive time with a 6-3 7-6(2) victory over Terence Atmane. The two-time Madrid champion looked to be cruising when serving for the match at 5-4 in the second set, but Atmane threatened a turnaround before Zverev regrouped to close out the tiebreak. The world No. 3's trademark baseline power was complemented by clever drop shots that disrupted the tricky left-hander's rhythm. With 27 wins from 33 matches in Madrid, Zverev now trails only Rafael Nadal, Roger Federer, Novak Djokovic and Andy Murray for most victories at the event. His win continues a remarkable 2026 turnaround after an inconsistent 2025 campaign, as he joins Jannik Sinner as the only players to reach the last 16 at all four Masters 1000 events this season.
Ruud dominates Davidovich Fokina
Casper Ruud proves to feel brilliant on Madrid's clay, as he delivers his most convincing performance in months, dismantling Alejandro Davidovich Fokina 6-3 6-1 in just over an hour. The Norwegian's aggressive return game proved devastating, converting 5 of 8 break point opportunities while never facing serious trouble on his own serve. Ruud's pressure-point dominance was particularly impressive - he won 11 of 21 return pressure points while maintaining solid composure with 4 of 6 serve pressure points won. The victory sets up an intriguing clash with Stefanos Tsitsipas, who earlier defeated the Spanish qualifier Daniel Merida Aguilar to reach the round of 16. Ruud's clay-court form over the past 12 months shows a strong 76% win rate, and this dominant display suggests he's finding his rhythm at the perfect time in the European clay swing. Despite his title defense chances being not rated very high before the tournament, Ruud shows a commanding form and can be a difficult opponent to beat in the bottom half of the draw.
Mensik outlasts Khachanov in tiebreak thriller
Jakub Mensik showcased his big-serving prowess in a hard-fought 6-4 7-6(11) victory over Karen Khachanov. The Czech youngster fired 14 aces and won 82% of first serve points in a serving display that overwhelmed the experienced Russian. The match turned on a dramatic second-set tiebreak that required 13 points to settle, with Mensik eventually prevailing after multiple set points for both players. His serve never came under serious pressure - he didn't face a single break point throughout the match while converting his lone opportunity on the Khachanov serve. The victory continues Mensik's steady progress on clay, where he now holds a solid 67% win rate over the past 12 months, and sets up a potential blockbuster clash with Alexander Zverev in the next round.
Cerundolo cruises past Darderi
Francisco Cerundolo produced a clinical display to defeat Luciano Darderi 6-2 6-3, extending his head-to-head advantage to 4-2. The Argentine was particularly effective on return, winning 9 of 20 return pressure points while maintaining perfect composure on serve by winning all 4 serve pressure points faced. Cerundolo's aggressive baseline game proved too much for the Italian, as he converted 3 of 7 break point opportunities while never allowing Darderi onto the scoreboard in terms of breaks. The victory showcases Cerundolo's consistent clay-court form, where he maintains a solid 65% win rate over the past 12 months, and sets up an intriguing encounter with breakthrough star Alexander Blockx in the fourth round.
Medvedev advances past NextGen qualifier
Daniil Medvedev continued his steady progress through the Madrid draw with a 6-3 6-2 victory over NextGen qualifier Nicolai Budkov Kjaer. The world No. 10 showcased his exceptional return game, which has been among the tour's best this season with a 32.5% return games won percentage. Medvedev won 12 of 20 return pressure points while handling the pressure moments on his own serve effectively with 7 of 12 serve pressure points claimed. Despite his well-documented struggles on clay, the Russian has shown improved form since the blowout against Matteo Berrettini in Monte Carlo, and his patient, methodical approach proved too much for the young Dane making his Masters 1000 debut.
Tuesday round of 16 preview
All the eight round of 16 encounters are scheduled to be played on Tuesday with a compelling line-up of matches to watch for the whole day in Caja Magica venue. Jannik Sinner looks forward to stunning 20th on-court victory in a row, facing Cameron Norrie who already played three tiebreaks, but got broken just once in two matches played in Madrid this week. Alexander Zverev faces Jakub Mensik, who has already proved to be able of making any upset, defeating Sinner in Doha two months ago. The Czech is yet to drop a set and single service game in Madrid Open.

The reigning champion Casper Ruud sets up an exciting clash against Stefanos Tsitsipas who looks in best shape since months, winning three matches in one ATP tournament for the first time since January's United Cup competition. Daniil Medvedev faces Flavio Cobolli in the meeting between one top player who dislikes clay and the other who displays his best performance on this surface. Although, Cobolli who climbes close to top 10 of ATP rankings, is yet to defeat Medvedev after their two matches, the last one played in 2024.

Sixth seed Lorenzo Musetti faces a difficult challenge against Jiri Lehecka who fired respectively 16 and 10 aces in his first two rounds, defending just two breakpoints so far in this tournament. Arthur Fils plays for the comeback to top 20 of ATP rankings. The Frenchman who plays brilliantly with 20-5 record in 2026 is just one match away from advance to possibly 18th place in live ATP rankings. His faces difficult opponent though, as Tomas Martin Etcheverry has also a great record of 20-9 including the title run on clay in Rio De Janeiro two months ago.

Spanish fans have just one home favorite to root for at the stage of round 16, but it's the possibly most exciting name of this week.
