Alexander Zverev is guaranteed to finish 2026 as the year-end No. 1 in ATP rankings after Carlos Alcaraz suffered a third-round exit at the Shanghai Masters.
Zverev secured confirmation following Alcaraz's straight-sets loss to unseeded Zizou Bergs and Jannik Sinner's earlier withdrawal due to a knee injury.
The German player became the first from his country to achieve the year-end top ranking, highlighted by his French Open and US Open victories.
