When the latest edition of the ATP singles rankings dropped earlier this week, a 24-year streak came to an end.
After being bounced in the first round of the US Open, Novak Djokovic dropped out of the top-10 for the first time since 2018.
Djokovic's exit marks the first time since October 2002 that neither he nor Rafael Nadal nor Roger Federer is inside the top-10.
For tennis fans who wondered when the 'Big 3' era in the men's game would end, the end is now.
Since first achieving a top-10 ranking in May 2017 as a 20-year-old, Zverev has been one of the most consistent performers on the men's tour.
Zverev has spent 414 weeks as a top-10 ranked player throughout his career, now 15th all-time.
Zverev has spent 102 consecutive weeks ranked inside the top 10 since his most recent streak began in September 2023.
Zverev's record pales in comparison to Alcaraz and Sinner, as well as Djokovic, Federer and Nadal.
Alcaraz has a 16-7 record against top-10 opponents at grand slams, with his 69.6 per cent conversion rate by far the best among the cohort, while Sinner has gone 14-14 in such matches.
Nadal, Djokovic and Federer all won over 60 per cent of their matches against top-10 opponents at grand slams, with Djokovic's 69 wins leading the way.
Overall, the average ranking of the players Zverev beat en-route to his first grand slam title is 57.7, with his fourth-round opponent, world No.106, Jesper de Jong the lowest-ranked.
