Breaking the rhythm, the key against Alcaraz and Sinner: Krajicek’s insight and what it reveals about modern tennis.
When Richard Krajicek says that to compete with Carlos Alcaraz and Jannik Sinner “you have to break their rhythm,” he is not offering a generic soundbite or a recycled talking point. He is speaking from the perspective of someone who understands how dominance is built at the highest level — and, crucially, how it can be challenged.

The comment, made in an analytical context rather than as a reaction to a single match, goes straight to the heart of modern tennis: control of tempo. Few players on today’s tour manage that element better than Alcaraz and Sinner.
Rhythm as a form of power
Both Alcaraz and Sinner impose matches that unfold at their preferred pace. This is not merely about raw power or constant aggression, but about continuity. They sustain long rallies without sacrificing depth or tactical clarity, forcing opponents to take risks again and again just to stay competitive.
That sustained rhythm creates mental fatigue as much as physical wear. Once a rival is drawn into the cadence dictated by either player, discomfort sets in. Shots feel rushed, decision-making becomes reactive, and confidence erodes. According to Krajicek, this is often where the line between “competing” and “being overrun” is drawn.
What “breaking the rhythm” actually means
Breaking rhythm does not mean hitting harder or accelerating indiscriminately. It is not about chasing quick winners or abandoning structure. In practical terms, it means disrupting the architecture of the point: changing height, speed, trajectory and timing.
Against players like Alcaraz and Sinner, that can take several forms:
- heavier, higher balls to alter contact points
- well-timed slices to pull them out of their preferred patterns
- selective net approaches to shorten rallies
- constant variation on serve and return
The goal is not to win points quickly, but to prevent the match from becoming automatic.
Why so few manage it
The difficulty lies in execution. Varying play without losing control demands exceptional precision. It is often far harder than sustaining a stable baseline pattern — especially against players who thrive on rhythm.
This is where another strength of Alcaraz and Sinner becomes evident: adaptability. When opponents succeed in unsettling them for stretches, both possess the tools to respond. They adjust court positioning, increase aggression, or simply raise their physical output to reassert control.
As a result, breaking rhythm may work in phases, but sustaining it across an entire match is what separates the handful of players who truly trouble them from the majority who eventually yield.
Surface and context matter
Krajicek’s insight is also closely tied to surface dynamics. On faster courts, where reaction time is reduced, disrupting rhythm can be more effective — particularly when backed by a strong serve. On slower surfaces, the challenge intensifies, as Alcaraz and Sinner have greater scope to rebuild points and re-establish their tempo.
Tournament context plays a role as well. In long weeks with accumulated fatigue, rhythm disruption can open cracks. In isolated matches on the biggest stages, margins are razor-thin and sustained pressure is harder to maintain.
A broader lesson about modern tennis
Beyond individual names, Krajicek’s observation highlights a wider truth about today’s game. Modern tennis is no longer won by power or talent alone, but by the ability to manage matches. Alcaraz and Sinner exemplify this evolution.
To challenge them requires more than a good day. It demands a clear tactical idea, executed with conviction and sustained over hours. Even then, success is never guaranteed.
Why the statement matters
Krajicek’s comment resonates because it does not oversimplify the challenge — it exposes it. Breaking rhythm is not a magic formula, but a necessary condition. It underlines just how high the bar has been set for anyone hoping to compete with the sport’s leading forces.
Alcaraz and Sinner dominate not only because of how they strike the ball, but because of how they control time within a match. As long as they maintain that command, opponents will be forced to search for increasingly complex solutions.
Who managed to beat them in the past year — and how
Focusing on the last competitive year, the list of players who have defeated Alcaraz and Sinner is short but revealing. In every case, a common thread emerges: disrupting rhythm and forcing discomfort.
Those who beat Alcaraz
Over the past twelve months, Cameron Norrie, Holger Rune, David Goffin, Jack Draper and Jiří Lehečka all found ways past the Spaniard on different surfaces.
Norrie prevailed in a long, physically demanding match built on consistency, depth and patience. His left-handed patterns, with frequent changes in height and direction, prevented Alcaraz from fully controlling rallies.
Rune succeeded through early intensity. Rather than settling into neutral exchanges, he varied height and timing and took initiative at key moments, particularly with his down-the-line backhand.
Goffin offered one of the clearest examples of rhythm disruption. Through experience and tactical awareness, he used flat shots, tempo changes and precise timing to interrupt Alcaraz’s flow. It was a victory rooted in anticipation rather than force.
Draper caused problems with his left-handed serve and measured aggression. He shortened points, approached the net selectively and avoided extended rallies, keeping the Spaniard uncomfortable throughout.
Lehečka imposed a direct, fearless approach. Flat hitting, early acceleration and constant pressure ensured Alcaraz never dictated play, particularly on return games.
Those who beat Sinner
Against Sinner, the list is even shorter: Novak Djokovic and Alexander Bublik.
Djokovic defeated him in the Australian Open semifinal by continually breaking rhythm — alternating pace and pause, deploying slice to disrupt cadence and managing key moments with superior tactical clarity.
Bublik took a radically different route. Extreme variety, unpredictable serving, constant tempo shifts and unconventional decisions prevented Sinner from settling into his usual clean, continuous ball-striking patterns.
The common pattern
Across styles, surfaces and personalities, the pattern is consistent: none of these players attempted to match Alcaraz or Sinner in pure rhythm. Instead, they altered tempo, disrupted structure and pulled the favourites out of their comfort zones.
That is where Krajicek’s reading holds its value. Breaking rhythm is not a guarantee of victory — but without it, matches tend to tilt quickly toward those who dominate the tempo.
