Alexander Zverev will replace Jannik Sinner as the men’s world number one at his earliest opportunity after reaching the quarter-finals in Vienna.
asserted
Zverev → publish → Vienna
Germany’s Zverev was already guaranteed to finish 2026 as the ATP’s leading player, but made sure he will rise to the summit on Monday with a 6-4 7-5 win over Tallon Griekspoor at the Erste Bank Open.
asserted
he → guarantee → Open
Zverev, 29, is the second German to reach the pinnacle of the men's tour after Boris Becker in 1991.
asserted
Zverev → reach → 1991
The achievement is a testament to his body of work this year, having won two Grand Slam titles and 64 of his 80 matches.

It's been a wait but sometimes you have to wait for the best things in life," said Zverev, who is the second oldest man to top the rankings for the first time.
asserted
who → have → time
"I'm super happy, super thrilled - I have no words for this year."
At the start of the year it seemed unthinkable that anybody other than Sinner or Carlos Alcaraz would become world number one.
asserted
anybody → have → Sinner
But the dominant duo have missed large chunks of this season through injury, opening the door for Zverev - who won the French Open and US Open titles with at least one of the pair absent - to take over.
asserted
who → miss → pair
Going into 2026, Alcaraz led the rankings with 12,050 points, closely followed by Sinner on 11,500.
asserted
Alcaraz → go → 11,500
The duopoly of the pair - who split all of the eight Grand Slam titles in 2024 and 2025 between them - was illustrated by the huge gap to the rest of the field.
asserted
who → split → field
Third-ranked Zverev had 5,110 points - closer numerically to the 2,221st player in the rankings than the top two.
asserted
Zverev → rank → two
Both his major triumphs came without having to face Sinner or Alcaraz, and he did not face a top-10 player until beating Ben Shelton in the New York final.
asserted
he → come → final
As the season entered its final stretch, Zverev achieved what many thought was impossible by securing the year-end number one ranking when Alcaraz lost in Shanghai on 12 October.
asserted
Alcaraz → enter → October
Zverev knew he still could not overtake Sinner until 2 November at the earliest, but beat Griekspoor to become the first man other than Sinner and Alcaraz to top the rankings since Novak Djokovic in June 2024.
uncertain
he → know → June
Zverev conceded he would "maybe not" be the world's best player if both his rivals were "healthy and at the top of their game".
asserted
rivals → concede → game
But he has efficiently beaten what has been in front of him, recording the greatest season of a career which had threatened to fall short of the lofty expectations placed on him since emerging as a teenage prodigy.
asserted
which → beat → prodigy
Fery continues to prove himself - and faces Zverev next
Zverev goes on to face British number one Arthur Fery in the quarter-finals - a repeat of their Wimbledon semi-final.
Fery, 24, made an unexpected run to the SW19 last four in July, but continued to prove he belongs among the world's best with a 6-4 5-7 6-4 win over Italy's Lorenzo Musetti in Vienna.
Trailing 4-2 in the decider, Fery showed his mental fortitude by breaking straight back and then overcoming what seemed to be cramp to serve out an impressive victory.
asserted
what → continue → victory
It is easy to forget Fery is still inexperienced at the elite level following his Wimbledon heroics.
asserted
Fery → forget → heroics
Beating former world number five Musetti - now ranked 26th after injury - represents his biggest win by ranking on the regular ATP Tour and provides another opportunity to test himself against the very best.
asserted
Beating → beat → best
However, Cameron Norrie fell short of his best victory of the season when world number five Daniil Medvedev saved match point to win their last-16 match.
asserted
Medvedev → fall → match
A frustrating year has seen Norrie drop to 41st in the world rankings and exit each of the past three Grand Slam tournaments in the first round.
asserted
Norrie → see → round
But the 31-year-old showed his key attributes - tenacity, athleticism and controlled aggression - to threaten a huge upset against Medvedev.
asserted
old → show → Medvedev
Third seed Medvedev, fresh from winning the Almaty title last week, was left angrily punching the surface when he fell a break down in the deciding set.
asserted
he → win → set
Norrie served for the match at 5-3 40-30, but Medvedev picked off his opponent's serve-volley attempt and fought back to win 4-6 6-3 7-6 (7-1).
asserted
Medvedev → serve → 4
Elsewhere, second seed Alcaraz progressed with a 6-1 7-6 (13-11) win over Georgia's Nikoloz Basilashvili.
asserted
Alcaraz → progress → Basilashvili
