There are few things more exciting, fair, and precise than the scoring system that governs the ATP ranking. However, this doesn't mean it is immutable, as the governing body of men's tennis has shown in recent years. In 2021, they already modified some parameters, and now they are going a step further, once again reshaping the system and causing unexpected consequences.
Many tennis fans are unaware of some intricacies of the ATP ranking scoring system. It is well known that results from the last 52 weeks are counted, meaning points from the previous edition of the tournament still count. But there is much more to it.
Starting in 2026, only the 18 best results will be considered for the ATP ranking
Not all results earned contribute to a player's ATP ranking points. From this season onwards, only the 18 best results will award points, as opposed to the 19 that were considered until the end of 2025. The 4 Grand Slams, the 8 mandatory Masters 1000, and four ATP 500 tournaments are the events every top 30 player must compete in.

Players can also compete in other events such as the Monte Carlo Masters 1000, additional ATP 500, or an ATP 250, but regardless of the number of tournaments they play, only the 18 where they earn the most points will be considered for the ATP ranking. This rule change came into effect on December 29, causing players like Alexander Zverev, Novak Djokovic, Félix Auger-Aliassime, Álex de Miñaur, and Taylor Fritz to lose points in their rankings.
Even though this modification does not significantly impact the rankings or alter positions, this new scoring system rule in the ATP ranking must be taken into account for the rest of the year, emphasizing that only the 18 best results will contribute points to each player's ranking column.
