Alexander Zverev is guaranteed to finish the 2026 season as world number one after Carlos Alcaraz’s surprise defeat in the Shanghai Masters. He will be the 30th man to be ranked number one on the ATP Tour.
German Zverev was on course to climb above current world number one Jannik Sinner, who has been ruled out for the rest of the year with a knee injury. Alcaraz still had a mathematical chance of stopping Zverev until he lost 7-5 7-6 (7-4) to Belgium’s Zizou Bergs in the third round on Monday.
“It’s been a fantastic season for me. Knowing that I will finish the year on top of the rankings is just a dream come true,” said Zverev.
After losing three major finals, Zverev won the first Grand Slam title of his career at the French Open in June. He followed that with victory at the US Open last month. The 29-year-old has taken advantage of the injury problems suffered by Spaniard Alcaraz and Italian Sinner, the dominant pair on the ATP Tour in the previous two seasons, to become the world’s leading player.
Zverev cannot overtake Sinner until 2 November at the earliest. He will become the first German man to end a year as world number one, and the oldest player to reach the top spot for the first time.
Zverev suffered a serious ankle injury in the 2022 French Open semi-finals that kept him out for seven months. He has since returned to the upper echelons of the sport and has been ranked inside the top four continuously since March 2024.
“So much work and effort have been put into achieving this goal, especially after coming back from the ankle injury. I look forward to finishing the season in style,” he added.
Analysis: How Zverev completed mission impossible
At the start of the year, it seemed unthinkable that anybody other than Sinner or Alcaraz would finish it as world number one. Going into 2026, Alcaraz led the rankings with 12,050 points, closely followed by Sinner on 11,500.
The dominance of the pair, who split all eight Grand Slam titles in 2024 and 2025 between them, was illustrated by the huge gap to the rest of the field. Third-ranked Zverev had 5,110 points, which was numerically closer to the 2,221st player in the rankings than to the top two.
As the season enters its final stretch, however, Zverev has completed what many thought was impossible. Sinner and Alcaraz both missed large chunks of the season through injury, and Zverev won the French Open and US Open titles with at least one of them absent. He did not face a top-10 player in either major until he beat Ben Shelton in the New York final.
Zverev has said he would “maybe not” be the world’s best player if both his rivals were “healthy and at the top of their game”. But, as the old adage goes, you can only beat what is in front of you. Zverev has done exactly that to record the greatest season of a career that had threatened to fall short of the lofty expectations placed on him since he emerged as a teenage prodigy.
Alcaraz has ‘negative thoughts’ after exit
Alcaraz has made encouraging progress since returning from a wrist injury that kept him off tour for almost five months. This defeat, however, was a reminder that coming back from such a long absence is not smooth sailing.
The seven-time Grand Slam champion was below the level he showed when he won the Japan Open last week, producing a string of uncharacteristic errors. “Today wasn’t a good match from my side. I didn’t feel good,” said Alcaraz, who also credited 39th-ranked Bergs for serving strongly and taking his chances.
“Right now, all the negative thoughts come to my mind and none of the positives, but I think [later] I will take the good things.”
Bergs, who showed great composure to serve out the biggest win of his career, faces American Tommy Paul in the last 16. Zverev remains in the draw as one of only three top-eight seeds left, alongside Canada’s Felix Auger-Aliassime and Russia’s Daniil Medvedev.
