Novak Djokovic is the oldest player to lead the rankings. Mariano Navone and Thiago Tirante were never so high.
The Serbian begins the slow court season on Tuesday with his participation in the Monte Carlo Masters 1000. The Italian Jannik Sinner retains second place with only 65 points ahead of the Spanish Carlos Alcaraz. The Polish Hubert Hurkacz rises two places and relegates the Norwegian Casper Ruud to 10th place. Sebastián Báez remains in 19th place despite his premature defeat in his debut in Monte Carlo.
