Staff Writer Shruti Kulkarni comments on the Alcaraz-Sinner rivalry.
Great tennis players are common. Great rivalries are not.
If you are a fan of tennis, it’s hard not to be a fan of the two young men who are currently writing tennis history with their era-defining rivalry. At just 25 and 23, Jannik Sinner and Carlos Alcaraz have already established themselves as the defining players of the new generation of men’s tennis. From the 2024 to the 2026 Australian Open, all 9 Grand Slams in between have been won by either of the two. This streak was only interrupted at Roland-Garros earlier this year, where an injured Alcaraz didn’t play and Sinner’s dramatic early exit saw Alexander Zverev winning his first Grand Slam title against Flavio Cobolli in the final.
What makes the two so fascinating is not merely their extraordinary statistics or how evenly matched they have become. It is how different they are. As we wait for the tennis world to descend in New York for the final Grand Slam of the year, let me take a look at the rivalry so far: the numbers, their contrasting styles, some of their most memorable encounters, and the storylines going into this year’s US Open.
Sinner vs. Alcaraz
First, let me load you with the statistics.
The current men’s World Number One, Jannik Sinner, has recently added to his collection of silverware, having successfully defended his Wimbledon title last month, becoming a five-time Grand Slam champion. Meanwhile, Alcaraz has seven Grand Slam titles to his name. His most recent came at the Australian Open in January, where he defeated a 38-year-old Novak Djokovic to complete the Career Grand Slam – becoming the youngest man in history to win all four majors.
While Alcaraz leads the rivalry in Grand Slam titles, Sinner currently leads in the ‘Big Titles’ race – which includes Grand Slams, ATP Finals, and Masters 1000 – 17 to 15. In their head-to-head, it’s Alcaraz who has the edge, leading 10-7.
For non-tennis watchers, this may be a bit overwhelming. All you need to know is: they are very, very good.
Alcaraz and Sinner turned professional in the same year, 2018, but their paths into professional tennis were quite different. Sinner started playing at seven, while Alcaraz picked up a racket at just four. Sinner also spent much of his childhood skiing, his first sporting love until the age of 13, something that, interestingly, is reflected in his exceptional movement around the court.
More than stats, however, what is much more interesting is what happens when the two step onto the court together.
Two very different styles
Hard-court specialist Sinner is often described as clinical, economical, and relentlessly efficient. His ball-striking and baseline consistency have earned him the title “the machine” (although he has debunked this narrative!) Sinner’s style can sometimes feel almost mathematical. He is remarkably good at optimising every shot and movement, wasting very little energy. Repeatedly hitting the same devastating shot until his opponent eventually has no answer.
Then there is Alcaraz.
His iconic performances on clay and inevitable comparison to fellow Spaniard and ‘King of Clay’ Rafael Nadal have often given him the title of the next clay specialist. But the truth is that Alcaraz has proven his skill on all courts – becoming a rare and exceptional case of an all-round talent on all surfaces, having equal success on hard court and grass.
Where Sinner makes tennis look like a science, Alcaraz often makes it look like art. He is explosive, unpredictable, and is willing and able to improvise when needed. His athleticism, drop shots, net play and seemingly endless ability to produce something spectacular have created some of the most memorable moments of recent tennis.
This contrast extends beyond their style of play.
As far as temperament is concerned, Sinner’s cool and calm composure extends his efficiency beyond the physical, allowing him to conserve energy mentally as well. He is typically restrained and rarely rises to even the most intense moments. He is extraordinary at maintaining his demeanour and rarely gives anything away to the opponent, making him a mental beast on the court.
Alcaraz, on the other hand, experiences a higher level of emotion on the court. The celebrations, the frustration, and the fist pumps are all a part of his game, often getting the crowd equally energised in doing so. His tennis feeds off his energy.
And perhaps this is where the most notable difference lies between the two powerhouses: consistency versus explosiveness.
Sinner’s great strength is his baseline. He can quietly and relentlessly wear an opponent down, producing an extraordinarily high level of tennis for an entire match. His consistency is one of the reasons he has become such a formidable presence at the top of the game.
Alcaraz, on the other hand, may not always have Sinner’s consistency, but his ceiling can feel almost limitless. You never know what Alcaraz has in store for his next shot. His game is capable of suddenly exploding into something extraordinary, a ridiculous forehand, an impossible defensive recovery, a drop shot from nowhere.
Sinner can make an opponent feel like they are slowly being suffocated.
Alcaraz can make them feel like they are being hit by a lightning bolt.
This is what makes their matches special. ‘What happens when an unstoppable force meets an immovable object?’ In physics, the two cannot coexist. But in tennis, somehow, Sinner and Alcaraz have managed.
The Birth of the Rivalry
To understand how we got here, let’s go back to the beginning.
Their first meeting came in April 2019 on the ATP Challenger Tour in Alicante. Here, a 15-year-old Alcaraz defeated 17-year-old Sinner in Alicante 6-2, 3-6, 6-3.
Their first meeting at the ATP (professional) level came later at the 2021 ATP Masters 1000 in Paris, where Alcaraz won again in a round of 32 match. Since then, they have faced each other 17 times professionally and nine of these have been finals – an astonishing testament to just how often these two find themselves competing at the sharp ends of tournaments. Their most recent meeting was the ATP Masters 1000 Final in Monte-Carlo where Sinner took the win on clay in straight sets.
The rivalry really began to capture the attention of the tennis world at the 2022 US Open.
The Matches
Before discussing 2022, however, it is hard to talk about Sinner and Alcaraz without talking about their 2025 Roland-Garros final.
Five hours and 29 minutes
Two sets down
Three championship points saved
A fifth-set super tie-break
And, ultimately, an Alcaraz victory and Sinner’s most devastating loss.
It was the longest men’s singles final in Roland-Garros history and to many, including myself, it is one of the greatest Grand Slam matches ever played.
Alcaraz eventually prevailed 4-6 6-7 (4-7) 6-4 7-6 (7-4) 7-6 (10-2) after saving 3 match points in the fourth set.
The match seemed to contain everything that makes the Sinner-Alcaraz rivalry so special: extraordinary shot-making, physical endurance, momentum swings, emotion, sportsmanship and, most importantly, the feeling that neither player was willing to let the other win.
It also felt like a changing of the guard. Grand Slam finals between Federer and Nadal, or Nadal and Djokovic, were once the matches that defined men’s tennis. Suddenly, two players born in the 2000s were producing something that could stand alongside them.
Yet, another match that deserves more attention when discussing the rivalry is the 2022 US Open quarter-final. At this point, neither had become the tennis superstars they are today, nor had they won a major title yet. This is why this match is so special. It now feels like the introduction to what the Sinner-Alcaraz rivalry became – a five-hour, five-set thriller, an Alcaraz comeback, outrageous shot-making, and an electric Flushing Meadows crowd. Alcaraz went on to win the entire tournament, winning his first Grand Slam title.
‘Sincaraz’ and the Big Three
Perhaps cliché at this point, but I must spare a moment to discuss the men who came before them.
Federer. Nadal. Djokovic. Three names that individually are synonymous with ‘tennis’
For almost two decades, men’s tennis was defined by three players whose rivalries produced some of the greatest matches and sporting stories of all time. It is therefore tempting to ask whether Sinner and Alcaraz are the new Federer and Nadal, and, inevitably, who will be their Djokovic.
But perhaps we should stop trying to recreate the past.
Having two generations of rivalries of this quality in succession is incredibly rare. We don’t know whether Sinner and Alcaraz will dominate men’s tennis for the next decade, whether another player will emerge to disrupt them, or whether their rivalry will eventually develop into something completely different.
What we do know is that we are lucky enough to be watching it happen.
So, what happens in New York?
This brings us to the US Open.
Usually, Sinner and Alcaraz are the obvious names at the top of the list of favourites, but this year they both arrive with very different storylines.
The Italian arrives in New York off the back of his Wimbledon win, returning to his favourite surface with momentum and confidence. Could he use that to close the gap between the two and claim his second US Open title?
Alcaraz, meanwhile, is making a much more dramatic return.
The Spaniard has been out since April due to a wrist injury, forcing him to miss both Roland-Garros and Wimbledon. He is confirmed to return at the US Open as the defending champion, ending a four-month competitive absence. Will the time off take him off his game, or will he be even hungrier for the win?
Sinner has momentum, but the particularly brutal turnaround from Wimbledon to the US Open could leave him overworked. Alcaraz will come to New York rested and fresh but may need more time to adjust to high-level tennis after four months off.
Interestingly, if they do meet each other, it may not be in the final. Alcaraz’s time off has made him the No.3 seed going into the tournament, meaning that he could face Sinner earlier than the finals. This is a rare scenario for the two and could play out dramatically given how deep they are in their careers now.
Alcaraz’s absence and Sinner’s early exit in Paris have, however, made room for Alexander Zverev, making the story more layered than before. Perhaps after the taste of a Grand Slam win and another final at Wimbledon last month, he may have more momentum than ever before.
Ultimately, the story in New York will most likely come back to the same two names but it certainly seems like we don’t know who will win yet. Either way, another chapter of ‘Sincaraz’ awaits and we will certainly be excited to see it unfold!
Update
Since this piece was originally written, the ‘overworked’ hypothesis may have been a foreshadowing as Sinner has withdrawn from this year’s US Open due to a knee injury. In a year full of withdrawals, injuries, and early exits, this is certainly a devastating blow for the tennis world, as we miss out on yet another potential blockbuster match-up between Carlos and Jannik.
Sinner’s absence does, however, lift some pressure from the Spaniard’s shoulders after the tumultuous year he’s had, making his return to the top level much smoother. With Zverev now the top seed, a likely final in New York could be Alcaraz vs Zverev -and after four months away from competitive tennis, a Sinner-free draw may make Carlos’ journey into that final considerably easier. Could Alcaraz defend his US Open title in what would be a rather heroic comeback?
