The ATP Rankings have returned to their usual 52-week calculating system this week, marking the end of a protracted period of covid-era adjustment. All the points held from competitions in 2019 and 2020 are gone with the conclusion of the ATP 1000 event in Montreal.
Therefore, the ATP Rankings are now restricted to results from the previous 52 weeks in accordance with the established merit-based ranking methodology in use since 1973. According to the most recent ATP Rankings, Daniil Medvedev continues to hold the top spot in the world.
Following him are Alexander Zverev, Rafael Nadal, Carlos Alcaraz, Casper Ruud and others. The fight for the number one ranking is in full effect and with this system, it's going to be a proper fair fight as it was for decades. The highest chance to finish number one at the end of the year has Rafael Nadal.
