Zverev Becomes Oldest First-Time World No. 1 in 52 Years
Alexander Zverev, aged 29 years and 196 days, is the new ATP world number one, becoming the second-oldest player to debut at the top.
Alexander Zverev is the new men's world number one. The 29-year-old German clinched the top ranking after winning two Grand Slam titles this year and defeating Tallon Griekspoor in the Vienna Open round of 16, with the ATP Tour confirming his position on Monday. Zverev is guaranteed to finish the year as number one after Carlos Alcaraz's loss in Shanghai, replacing Jannik Sinner who is sidelined for the rest of the season with a knee injury.
Zverev won the French Open in June by beating Flavio Cobolli in the final. He followed that by overcoming Ben Shelton to claim the US Open title in September. Those major triumphs, achieved without facing rivals Sinner or Alcaraz, helped him compile a 65-17 match record this year. He has now won 64 of his 80 matches in 2026. Zverev will make his first appearance as the top-ranked player at the Paris Masters.
Historic age record
At 29 years and 196 days, Alexander Zverev is the second-oldest player ever to debut as world number one in singles. Only John Newcombe was older, reaching the summit at 30 years and 11 days back in 1974. This makes Zverev the oldest first-time number one in over fifty years. He is the 30th man to hold the top spot since the ATP rankings began in 1973 and only the second German to do so, joining Boris Becker who first achieved the feat in 1991.
The five oldest male players to debut at number one since 1973 are:
| Player | Age at First No. 1 Ranking |
|---|---|
| John Newcombe | 30 years, 11 days |
| Alexander Zverev | 29 years, 196 days |
| Andy Murray | 29 years, 176 days |
| Thomas Muster | 28 years, 133 days |
| Ilie Nastase | 27 years, 39 days |
Career achievements
Zverev's ascent caps a career that now includes two Grand Slam singles titles. His trophy cabinet also holds an Olympic singles gold medal, two ATP Finals titles, and seven Masters 1000 trophies. He reached the Wimbledon final this year, losing to Jannik Sinner, and also made the Australian Open semifinals. Zverev had been ranked number two more than four years ago before this breakthrough.
Sinner's injury and Alcaraz's loss
The path to number one opened due to setbacks for the sport's recent dominant duo. At the start of the year, it seemed unthinkable that anyone other than Sinner or Carlos Alcaraz would reach the top. The pair had split all eight Grand Slam titles between them in 2024 and 2025. Going into 2026, Alcaraz led the rankings with 12,050 points, closely followed by Sinner on 11,500, while third-ranked Zverev had just 5,110 points.
That duopoly fractured when both missed large chunks of the season. Sinner announced the end of his season three weeks ago due to inflammation in his right knee. He had held the number one ranking since April 13 and has now slipped to second. Alcaraz's loss in Shanghai then guaranteed Zverev would finish the year on top.
Paris Masters outlook
Zverev begins his Paris Masters campaign with a bye in the first round. He will face Italy's Lorenzo Musetti in the second round. Musetti, a former world number four who recently won the Lyon Open, defeated Hubert Hurkacz in his opening match. The winner of that contest will face either Luca Van Assche, Learner Tien, or Stefanos Tsitsipas in the third round.
Zverev's projected path to the Paris title could see him face Alex de Minaur in the quarter-finals, Ben Shelton in the semi-finals, and Carlos Alcaraz in the final. In other ranking news, 20-year-old Rafael Jodar broke into the top 10 in just 287 days after his Tour debut at the Australian Open, surpassing the previous record held by Gustavo Kuerten. Zverev's first match as the confirmed world number one will be against Musetti in Paris.
