Jannik Sinner produced a controlled performance to defeat Felix Auger-Aliassime 6-3, 6-4 and reach the semi-finals of the
Monte-Carlo Masters, confirming a shift in level after a more complicated previous round. The Italian, who had struggled at times against Tomas Machac, responded with a more structured display, built on precision rather than risk.
The win extends Sinner’s run to 20 consecutive victories at the ATP Masters 1000 level, placing him alongside the likes of Novak Djokovic in a historically selective group. It also reinforces his current position as one of the dominant players on Tour, following titles in Paris, Indian Wells and Miami.
Across the three matches played in
Monte-Carlo so far, Sinner has faced contrasting conditions—different opponents, styles and rhythms. That variation has forced adaptation rather than continuity, particularly given the quick transition from hard courts to clay. Against Auger-Aliassime, that adaptation appeared more complete, even if not yet optimal.
The semi-final now brings a higher-level test against Alexander Zverev, who advanced after defeating Joao Fonseca in three sets. With both players familiar with each other’s games and Sinner holding a strong head-to-head advantage, the encounter will serve as a clearer indicator of his current level on clay.
A step forward after inconsistency
Sinner framed the win as progress within a broader adjustment process, highlighting the differences between each match played during the week. His opening rounds exposed fluctuations in rhythm and physical condition, but against Auger-Aliassime, he showed greater control, particularly in managing rallies and key moments.
“These three matches were very different," Sinner said after the quarterfinals victory. "The first was against a left-hander. Yesterday I didn’t find my rhythm. And today it was against someone I know quite well. I’m trying to get used to the sliding, the movement, but also the way of playing on this surface. It’s a bit different. I think there are positive aspects, but also things to improve after this tournament.”
The performance itself reflected that adjustment. Sinner dictated play from deep positions behind the baseline, limiting Auger-Aliassime’s opportunities and conceding just one break point across the match.
While his first-serve percentage remained modest - just 58% against Auger-Aliassime -his efficiency on key points and ability to absorb pressure marked a clear improvement from the previous round. “It was a step forward today. I knew I had to get better in certain areas.”
Efficiency, momentum and the bigger picture
Beyond the immediate result, Sinner’s run in Monte-Carlo is tied to a broader momentum that has defined his season. With 20 consecutive Masters 1000 wins and 39 victories in his last 40 sets at this level, his consistency across tournaments has become a defining factor, even as he continues refining elements of his game on clay.
At the same time, he acknowledged that key components—particularly the serve—remain below his expected standard. That self-assessment aligns with the match data, where he compensated for a lower first-serve percentage through strong baseline control and effective net approaches, winning the majority of his points when moving forward.
“The serve is not there yet, but all things considered I’m very happy to be into the semi-finals. Yesterday I was very tired but I recovered very well after a good night’s sleep.”
The upcoming match against Zverev introduces a different tactical challenge. While Sinner leads their head-to-head 8–4 and has won their last seven meetings, their record on clay remains balanced. In Monte-Carlo specifically, Zverev holds a previous win, underlining the narrow margins expected in the semi-final.
For Sinner, the objective extends beyond reaching another final. With the possibility of reclaiming World No. 1 from Carlos Alcaraz still in play, and the chance to become the first player since Djokovic in 2015 to win the first three Masters 1000 events of the season, the stakes continue to rise. His progression, however, remains grounded in incremental improvement rather than immediate dominance.
