Breaking details:

Top men's players, led by Djokovic, Pospisil, are breaking away from ATP to form the Professional Tennis Players Association.

Djokovic, Pospisil, Isner resigning from player council.

From me for @NYTSports, with @christophclarey: https://www.nytimes.com/2020/08/28/sports/tennis/tennis-union-men-djokovic.html

In a letter pleading with ATP players to reconsider, ATP chairman Andrea Gaudenzi framed the Professional Tennis Players Association as an existential threat to ATP, which has existed as a cooperative structure with power shared between players and tournaments.

Last year Pospisil spoke frequently and eagerly about the opportunity to include WTA players as he envisioned a new players association that would serve as a sort of union.

The PTPA, however, is men-only, formed solely in opposition to ATP.
