The Sinner era: Is it actually good for tennis?

In the men's game, 2026 has, so far, been the Sinner era.

It started as the Alcaraz era after the Spaniard completed the set of Grand Slam titles at the 2026 Australian Open, before more silverware at the Qatar Open.

Then, after a couple of surprising losses and a wrist injury that he sustained in Barcelona, the Spanish superstar is now on the sidelines until at least Wimbledon.

Since then, Jannik Sinner has not only been dominant but largely unchallenged.

As it stands, the stats speak for themselves: 

Sinner has five consecutive Masters 1000 titles, is on a 27-match winning streak and is at a level so far above the field that even the closest challenger is being brushed aside with unsettling ease.

The 24-year-old is even rewriting the history books after overtaking Novak Djokovic as the player with the most consecutive Masters 1000 match wins (32 and counting).

Right now, this doesn't feel like dominance anymore — it feels like suffocation and a creeping sense of inevitability to boot.

And maybe most telling of all? The matches don't feel competitive.

A gap that's becoming uncomfortable

Alexander Zverev is the world No.3 in all but ranking — and right now, he looks like a bystander.

Nine straight losses to Sinner. Fourteen consecutive sets gone. That doesn't feel like a rivalry. It feels like a pattern.

After being dismantled in Madrid, Zverev didn't dress it up in his post-match press conference.

"There is a big gap between Sinner and everyone else right now," he said.

Leading UK tennis commentator Nick Lester concurs with this assessment.

"I don't think it's a great look when you have a player winning a Masters 1000 final in 58 minutes," Lester told The First Serve.

And when the second-best player in the draw is openly admitting the distance, it raises an uncomfortable question:

Is this actually good for tennis?

Listen to The First Serve Live every Monday at 8pm AEST in its 18th year on the SEN Network/App, Australia's only dedicated weekly tennis program on commercial radio running through till the end of November.

So… is it getting boring?

"I wouldn't call it boring, but I certainly think he needs a challenger, for sure, to keep things interesting," Lester believes.

He also believes that there are two ways of looking at Sinner's dominance right now.

"You can admire what he does, obviously, and the quality that he produces, but I don't necessarily think him being out on his own, minus Alcaraz absent, is necessarily great," Lester mused.

What Sinner is doing is historically significant. There's precision in his game, a completeness that leaves almost no tactical holes. Even Zverev pointed to it, describing his game as "very stable" and without "dips".

And that's the problem.

Sport thrives on vulnerability, on moments where the outcome feels like it could swing.

Right now, Sinner is basically impenetrable and, in the last few months, no one has found a way to pierce his armour.

The Alcaraz absence and the Djokovic question (again)

Carlos Alcaraz — the one player capable of turning Sinner matches into something unpredictable — isn't here, which does put a very small asterisk on some of the World No.1's results without taking anything away from Sinner, who can only play who is in front of him.

A lingering wrist injury has forced Alcaraz out of Madrid, Rome, and even Roland-Garros, removing the sport's most compelling rivalry at the exact moment it's needed most.

That's not to diminish what Sinner is doing — he beat Alcaraz in the Monte-Carlo final and holds his own in that matchup — but it does change the ecosystem.

Without him, the draw opens up — not just structurally, but emotionally.

And then you have Novak Djokovic

Djokovic is one of the few players who has shown he can disrupt Sinner's rhythm — most notably at the Australian Open earlier this year, where he outlasted him in five sets.

Not just because of the result, but because of how it looked: messy, physical, uncomfortable. The kind of match Sinner hasn't been forced into often enough lately.

On clay or in best-of-five sets, does Djokovic still have the legs to consistently challenge him? Probably not across a season.

But in one match? In one tournament? That's enough to reintroduce doubt in the Italian's mind.

Right now, aside from Alcaraz and Djokovic, there is no one consistently pushing him. There's no tension, no contrast, no sense that Sinner might be dragged somewhere uncomfortable.

And that's exactly what the sport is missing right now.

A Complete Game

When you break down Sinner's dominance, it all begins with the serve, according to Lester. 

"If you look at this year, he's won 27 matches at Masters level, and only eight players have broken him in those 27 matches," Lester relayed to The First Serve.

"The numbers he's posting right now this year are at 94 per cent of holds. That's sort of John Isner territory." 

Having such a dominant serve has freed up the Italian to pile pressure on during return games, of which Lester revealed he is also posting tour-leading numbers.

"He's been the tour leader in break points saved over the last two to three years, Sinner. So he's playing the big points exceptionally well," he said.

Breaking his game down further, Sinner's groundstrokes are perhaps the most penetrating on tour. Not only that, the world No.1 has added layers to his game, which Lester explained has enhanced his already stacked arsenal of tools.

"It's a two-pronged attack, like a lot of the young players now. He can hurt you off both wings, forehand and backhand," he explained.

"And he has continued to develop his game. We've seen him use the drop shot very effectively over the last few weeks. So yeah, I think he's just been willing to look to have that growth mindset as a player."

Who can actually stop him?

If the question is about the next three months, the answer is simple:

Alcaraz, when healthy, is still the most natural disruptor. Djokovic, on occasion, can still problem-solve his way through. Beyond that, it's a projection more than evidence.

For Lester, one player who stands out as a potential challenger is Frenchman Arthur Fils.

"I think he's got a huge game. I think he's got a great belief in himself. He's got a great attitude as well," said the well-renowned commentator.

"He's got the biggest forehand in the men's game right now in terms of speed and spin. No one comes near him. He's a great athlete. He's going to be one of those French players in Paris that rises to the occasion and rides the wave of the French support."

The 21-year-old has been outstanding since his comeback this year, winning 22 of his 28 matches in 2026 prior to Rome. He won the Barcelona Open last month, and was also a runner-up in Doha, a semi-finalist in Miami and a quarter-finalist in Indian Wells.

Unfortunately, after an apparent hip injury forced him to retire against Italian Andrea Pellegrino at the Rome Masters, Fils is now doubtful for his home Slam.

Still, even with Fils' injury, it's all speculation. 

Rafael Jódar is emerging but unproven. João Fonseca needs time to fine-tune his game. Alexander Blockx and Dino Prižmić are future contenders, but face the same problem of time.

This is not to say Sinner needs to lose for tennis to become interesting. It simply needs a reason to doubt him to create a little tension.

The Verdict

There's a tendency to frame dominance as inherently positive.

The Big Three era thrived on it. Djokovic, Roger Federer, and Rafael Nadal didn't just win — they defined tennis for nearly two decades.

But they also had each other. 

Sinner's dominance, at least right now, feels isolated.

Yes, his level is absurd — he's winning across all three surfaces, barely dropping sets, and rewriting what consistency looks like at Masters level.

But without resistance, dominance risks becoming repetitive, eventually predictable.

Sinner's dominance isn't boring yet, but it's drifting in that direction.

Not because of him — but because of what's missing around him.

No Alcaraz, a one-sided Zverev matchup and an ageing Djokovic who can't be everywhere anymore.

Right now, we're not in a rivalry-driven era; it feels much more singular, and I'm not sure it’s good for tennis.

Tennis, historically, has always been at its best when greatness has something staring back at it. 

Sinner, for the time being, doesn't.
