Agassi, Raducanu and the Four-Year Problem: How Tennis Is Relearning How to Measure a Player

In his interview with the BBC, Andre Agassi said something that, if pasted on the corridor wall of any Grand Slam venue, would read almost like a provocation: do not measure a player's daily effort by the results she collects. The recipient of that advice was Emma Raducanu — the 2026 US Open champion, the 23-year-old Briton who is still being measured by the tennis public against exactly one milestone in her career. What matters here is not the content of the advice; it is as old as the sport itself. What matters is who delivered it: a man who once fell to No. 141 in the world, who spent years hitting balls like a machine, and who only found himself again after burning through most of an athlete's youth.

The coincidence that gives this story its weight is not that Agassi said it, but that he lived it. And precisely because of that weight, the story is being told in a far lazier way than what actually happened.

Context: a man who fell to No. 141, and an 18-year-old who won the US Open

Andre Agassi finished his career with eight Grand Slam titles, including a rare feat recorded only for a handful of names in tennis history: he won all four majors and an Olympic gold medal. But the stretch between his two peaks is the part being discussed most in recent days. After his 2026 Australian Open title, Agassi entered a prolonged slump. He dropped out of the world's elite, falling as low as No. 141 — a number any former world No. 1 regards as an abyss. He came back to win Roland Garros in 2026, meaning roughly four years separated his two runs to a Grand Slam trophy.

In 2026, Agassi published his autobiography, "Open." The book quickly outgrew the category of a sports memoir to become one of the most cited documents on the psychology of elite athletes: hating the sport you play, the hairpiece, the addiction, the broken marriage, and the long work of rebuilding yourself from the inside. Fifteen years after publication, it is still being reactivated as a media asset.

At the other end of the story sits Emma Raducanu. In September 2026, at 18, she came through qualifying to win the US Open, winning ten straight matches without dropping a set. It was one of the biggest explosions in modern women's tennis. Since then, she has not reached a single Grand Slam quarter-final. Four years have passed, and every time she walks onto a court, the public places the same yardstick on her shoulders: that September afternoon.

Naomi Osaka enters the story in a different role. The Japanese player owns four Grand Slam titles and, this season, reached the semi-finals of a major for the first time in years. Notably, Osaka has also said she found something in Agassi's book.

Three destinies, two generations, one book, and an interview published on 23 September. That is the entire raw material. The rest of the story is how the sports industry handles it.

Core: an industry arguing about a slump nobody has defined

Based on my experience covering matches over more than two decades, I have noticed one troubling thing that all sports share: we argue loudly about a phenomenon while never agreeing on how to measure it.

Agassi's advice, stripped of context, sounds so simple it borders on meaningless: focus on the daily work, do not let results determine your worth, be comfortable in your own identity. But placed against the life the 57-year-old actually lived, it becomes a statement about methodology rather than motivation.

Here is the problem: the public debate about Raducanu runs almost entirely on results. Quarter-finals, semi-finals, finals. Blunt milestones. Meanwhile, the data set tennis owns is anything but poor: first-serve points won, second-serve points won, break-point conversion, return games won, points lasting beyond five shots, metres covered per point. These are the equivalents of the process metrics football uses to separate results from actual performance.

Almost nobody uses them to talk about her. Raducanu's slump is asserted, not quantified.

This is where I think about football, the sport I have lived alongside for too long. For years, distance covered was sold as a measure of effort. A player running twelve kilometres was praised on every bulletin. But if you sit in the stands long enough, you see it: running a lot can be a symptom of always chasing the ball, always being out of position, always reacting late. A pretty number does not equal quality. That is the trap any sport can fall into when it needs an easily explained metric for a mass audience.

Tennis is in exactly that trap, but from the opposite direction. It is so fixated on results that it ignores process. And when an entire media ecosystem only counts quarter-finals, any player who fails to reach them gets pushed into the same dark room — regardless of whether, inside that room, she is improving or falling apart.

There is a larger gap, even less discussed than the data: the structure of the sport. Ranking determines direct entry versus qualifying, seeding, wildcards, and the likelihood of drawing a strong opponent in round one. For a young female player, ranking also determines her place on billboards — and commercial clauses are often tied tightly to that ranking.

Asking a 23-year-old athlete not to measure herself by results is a spiritual request, but it runs head-on into an economic system that operates entirely on results. Not every player has the luxury of ignoring the scoreboard.

What makes Raducanu's situation distinctive is the decoupling of commercial value from sporting achievement. Since 2026, she has remained one of the most sought-after sports figures on the planet, with an endorsement portfolio reportedly far exceeding her prize money. That decoupling has two opposite consequences. On one hand, it buys her time to experiment, fail and try again without being abandoned. On the other, it sustains a constant stream of attention — and constant attention is the main ingredient of the build-them-up, tear-them-down cycle.

In this industry there is a cycle I have watched enough to recognise by its face. First comes sanctification. Then the question of legitimacy: was that victory luck? Then the countdown phase — every passing season is another declaration that time is running out. Finally, if the player does not break, the coverage shifts to a narrative of resilience. Agassi now stands at the end of a long cycle; Raducanu is somewhere in the middle of a second one.

Agassi's book plays a clear role in how this story is staged. A memoir published in 2026 — fifteen years ago — is still being cited by two active players at different stages of their careers as a reference point. It is a rare kind of intellectual property in sport: it outlives the career of the person who created it, and it keeps paying out every time someone needs a story about overcoming themselves.

But one small detail needs correcting, because small details always decide the credibility of a whole narrative. In recent days the slump has been described in some places as "five years." Raducanu won the US Open in September 2026. Counting to the date of this report, the gap is four years. One year is not much in a life, but it is enough to show that someone is retelling the story from memory rather than from data. For a 23-year-old born in November 2026, one year is nearly five percent of her life.

That small detail matters, because it is evidence that this debate runs on feeling, not measurement.

On Osaka's side, the argument is even more fragile. A player reaching a Grand Slam semi-final after years away is a welcome story. But reading it as proof that Agassi's book produces results is a logical leap with no foundation I can see. Two players reading the same book does not create an equation. What they share is having won a major very young, having been crushed by public opinion, and having had to rebuild everything. That is a shared fate, not a shared method.

Contrarian angle: two anecdotes do not make a rule

In sports analysis there is one recurring error so common it is almost an instinct of the trade: using a successful case to prove a principle. Here we have two cases. Agassi took nearly four years to climb back from No. 141. Osaka also returned after a long stretch. The conclusion drawn: patience will be rewarded.

But turn over the full history of tennis and you will find a far longer list of young champions who never came back. Players who broke through at 18, touched a major, then faded — through injury, through coaching changes, through bodies that could not withstand the workload of a professional season, or simply because they reached their own ceiling earlier than others. The base rate of returning to the top after a major slump is low. The story's failure to acknowledge that base rate is editorially understandable, but it makes the conclusion more fragile than it looks.

There is another point often forgotten when Agassi is quoted as proof of mental strength. His comeback did not happen only in his head. It was also a prolonged physical and stylistic reconstruction — a body rebuilt, a nutrition regime torn up and rewritten, a man in his thirties forced to accept he was no longer the 20-year-old unleashing one-handed backhands with his whole body. Keep only the mental part and discard the physical, and we are telling half a story and calling it a lesson.

I write from the inside, where outside noise cannot touch the pulse. From that position, the worry is not that people praise Agassi. It is that they turn patience into a media label while the competitive system still runs on seeding, ranking points, and contract clauses that can be cut when a ranking falls. Patience is a beautiful choice. It is not free.

What to watch next

Raducanu will enter the coming Grand Slams with the same question hanging overhead: is she improving or standing still? The answer will not be found in quarter-finals. It lies in the metrics almost nobody publishes in the evening bulletins — second-serve points won, break-point conversion, return games won against top-20 seeds. If Raducanu keeps losing while those numbers rise, Agassi will be right on method. If they stay flat, this debate needs to start over.

The pulse was never in the ball; it is in the people. Tactics will age, but human stories never expire. What is missing from this way of telling them is precision — the only thing that can turn a beautiful piece of advice into a verifiable conclusion.
