For years, Alexander Zverev’s career threatened to become a tale of heartbreaking near misses.
Three Grand Slam finals had brought him tantalising close to the game’s biggest prizes, but each time the trophy eluded him. An opportunity to claim both a maiden major title and the world No.1 ranking had ended in even greater anguish.
At Roland Garros four years ago, Zverev was three hours and 13 minutes into a semifinal against 13-time champion Rafael Nadal when a devastating ankle injury saw him leave the court in a wheelchair.
Winning the title would have taken him to world No.1. Instead, he required surgery to repair three torn lateral ligaments and spent the next six months on the sidelines.
But in a transformational 2026, Zverev has at last scaled the pinnacle of tennis.
Crowned champion at Roland Garros and the US Open – plus a finalist at Wimbledon and an AO semifinalist – the 29-year-old is now the new men’s world No.1, overtaking Jannik Sinner who had held the top spot since April.
“I had to wait,” said Zverev, the 30th player to achieve the ATP milestone and the second German after Boris Becker’s rise in 1991.
“But sometimes you’ve got to wait for the best things in life … I’m super happy, super thrilled.”
Born into a tennis family, Zverev seemed destined for a playing career. His parents, Alexander Snr and mother Irina, were each professionals in the former Soviet Union, while older brother Mischa followed the same path after the family’s relocation to Germany.
Zverev has recounted tales of hitting balls before his second birthday and spent much of his childhood mingling with champions at tournaments throughout the world.
But resilience was required in Zverev’s tennis journey from the outset.
In 2022, the German revealed he was diagnosed as a Type 1 diabetic as a four-year-old and doctors advised his mother her son's dream to succeed as a pro player was out of reach.
“No matter what obstacle was going to be in my way, she was not going to let anything stop me,” Zverev, who describes his mother as his most prolific influence, told ATPtour.com.
Zverev is similarly candid about the on-court battles he’s endured.
In 2020, he twice came within two points of claiming the US Open final before Dominic Thiem prevailed in five sets.
He led Carlos Alcaraz by two sets before losing the Roland Garros 2024 decider, then cast a forlorn figure after Sinner clearly outplayed him in the AO 2025 final.
“I don't want to end my career as the best player of all time to never win a Grand Slam, that's for sure,” Zverev lamented. “I'll keep doing everything I can to lift one of those trophies.”
A vow to take a more aggressive approach eventually paid off.
Even after surrendering a 5-3 lead to Carlos Alcaraz in the AO 2026 semifinals – a near five-and-a-half hour epic that became Melbourne Park’s third-longest match – Zverev could recognise the signs of progress.
“If I continue playing that way, if I continue training the way I train, if I continue working on the things that I've been working in the off-season, I do believe it's going to be a good year for me,” he said.
Those words rang true at Roland Garros, where Zverev’s more attacking approach helped him overcome first-time finalist Flavio Cobolli. At last, a five-set Grand Slam final had gone his way.
"This trophy for me is very important because if I would have lost this one, this self-belief would have gone down a lot," Zverev said. "But now that I've won it, I feel like I can do it again."
He almost did so immediately, charging into a first Wimbledon final and pushing Sinner to four sets. A third straight major final followed at the US Open, where Zverev withstood an inspired local favourite in Ben Shelton to win his second Slam, and 26th singles title overall.
“It feels amazing, especially with the heartbreak I had in 2020 here,” he commented, the scars of earlier Grand Slam losses now healed.
“Before winning in Paris, I felt a lot of stress all the time, because there was always a question mark, Will I ever win one? What I think now is just more of a joy to play those kind of finals.”
The one asterisk, arguably, is the dearth of top-10 victories, Zverev a winner of just three matches he’s contested against opponents of that calibre this year.
Still, as the oldest player in 50 years to become world No.1 for the first time, and only the fifth active player to do so – alongside Sinner, Alcaraz, Novak Djokovic and Daniil Medvedev – Zverev can trust in his persistence.
As he prepares for a 12th Australian Open, and a first as the top seed, Zverev will return to Melbourne with both unfinished business and new perspective on the possibilities.
“No words can truly describe this year,” he wrote in a first-person essay for ATPTour.com.
“To be able to feel what it is like being on top of the world is amazing. I’ve been able to win many important tournaments in my career. But having the No. 1 next to my name is such a special feeling that is impossible to describe.”
