Alexander Zverev has finally secured the ranking that repeatedly seemed within reach and then slipped away. The 29-year-old German will become the world’s No. 1 men’s tennis player for the first time when the ATP rankings are updated Monday, November 2.
Zverev guaranteed the move by defeating Tallon Griekspoor 6-4, 7-5 in the second round of the Vienna Open on Thursday. The straight-sets victory sent him into the quarterfinals and gave him enough ranking points to overtake Jannik Sinner regardless of what happens next in the tournament.
A victory with significance beyond Vienna
The scoreline looked routine, but the result carried historic weight. According to the ATP’s official announcement, Zverev will become the 30th man to reach No. 1 since the computerized rankings began in 1973.
He will also become only the second German man to hold the top position, following Boris Becker, who first reached No. 1 in January 1991. At 29 years and six months, Zverev is the second-oldest player to become No. 1 for the first time. John Newcombe was 30 when he reached the summit in 1974.
Zverev sealed the match against Griekspoor with an ace, taking one service break in each set. The win improved his 2026 record to 64-16 and sent him into a tour-leading 13th quarterfinal of the season. He is scheduled to face Britain’s Arthur Fery for a place in the Vienna semifinals.
The ranking that injury delayed
The milestone arrives more than four years after Zverev’s first serious push for the top ranking ended abruptly. During his 2022 French Open semifinal against Rafael Nadal, he tore ligaments in his ankle and missed the rest of that season. He had already reached No. 2, but the injury halted his momentum at the moment he appeared closest to taking the lead.
Reuters reported that Zverev marked Thursday’s achievement in an on-court ceremony with his team and former No. 1 Thomas Muster. Zverev described the feeling as distinct from winning a tournament because it reflects performance sustained across an entire season.
That season has been the strongest of his career. Zverev won his first Grand Slam titles at the French Open and U.S. Open, reached the Wimbledon final and advanced to the Australian Open semifinals. Those results had already guaranteed him the year-end No. 1 honor; the Vienna victory established the exact date he will formally take the top spot.
Why the change is happening now
Zverev will replace Sinner, whose latest stay at No. 1 began in April. Sinner ended his season early because of inflammation in his right knee, while injuries also interrupted Carlos Alcaraz’s year. Their absences helped open the rankings race, but Zverev still had to stay healthy and accumulate points consistently across all four major tournaments.
The Associated Press confirmed that Monday’s change will occur regardless of Zverev’s remaining results in Vienna. It will also make him the first player other than Sinner, Alcaraz or Novak Djokovic to hold the men’s No. 1 position since Daniil Medvedev’s brief reign in 2022.
The next challenge begins at the top
Reaching No. 1 ends one chase and begins another. Every opponent now gets a match against the official standard-bearer of the men’s tour, and Zverev must defend the points produced by a two-major season. Sinner and Alcaraz remain younger rivals with significant Grand Slam success and clear paths back into the race once healthy.
For now, the ranking validates Zverev’s durability after an injury that once threatened to redefine his career. Monday’s update will turn a long-promised possibility into an official line in tennis history: Alexander Zverev, world No. 1.
