Germany’s Alexander Zverev has moved to the top of the men’s tennis world rankings for the first time in his career after defeating Dutchman Tallon Griekspoor in straight sets at the Vienna Open on Thursday, October 29, 2026.
The 29-year-old secured a 6-4, 7-5 victory to advance to the quarter-finals of the ATP 500 tournament in Austria, achieving a major milestone in his professional career.
According to a report by Vanguard, Zverev was already assured of finishing the season at the summit of the ATP rankings. However, the absence of reigning world No. 1 Jannik Sinner, who ended his season early in October because of a knee injury, opened the door for the German to claim the top position in the next rankings update.
The new rankings, expected to be published on Monday, will make Zverev the 30th man to reach world No. 1 since the ATP rankings were introduced in 1973.
He will also become the second-oldest player to reach the top position for the first time, at 29 years and 196 days, behind Australian tennis great John Newcombe.
Zverev’s rise to the summit marks a significant achievement for a player who spent years pursuing the biggest prizes in tennis. His consistent performances throughout the 2026 season have strengthened his position among the sport’s leading competitors.
The German secured his place in tennis history after winning his opening two matches in Vienna, including a hard-fought first-round encounter against Spain’s Martin Landaluce.
Zverev had to save four match points against Landaluce on Tuesday before progressing, demonstrating the resilience that has characterised his campaign. He produced a more controlled performance against Griekspoor, taking the opening set 6-4 before sealing the second 7-5.
The match featured an unusual interruption when Zverev approached match point and a smash from his racket reportedly caused part of the electronic advertising board behind Griekspoor to malfunction. Play resumed after the umpire covered the affected panel with a towel, and Zverev completed the victory with an unreturnable serve.
The achievement comes ahead of the ATP Finals scheduled for next month, where the world’s leading players will compete in the season-ending championship.
Zverev’s ascent also highlights the changing landscape of men’s tennis, with the German joining an elite group of players who have reached the pinnacle of the sport. His first appearance at world No. 1 represents a landmark moment after years of competing against established champions for the biggest titles.
With the Vienna Open still underway, Zverev will now turn his attention to the quarter-finals as he seeks to maintain his momentum and strengthen his position heading into the final stretch of the season.
