Predict when these players will retire.

[FedExpress117]

There is a huge difference between retiring and starting to play badly (such as falling outside the top 10/top 20), but here are my guesses as to when these players will retire? What about you guys?

Federer - 2015 US Open
Nadal - 2016 French Open
Djokovic - 2019
Roddick - 2015 US Open (I really hope he wins a Wimbledon by then too)
Hewitt - 2014
Del Potro - 2020 (if he's healthy)
Murray - 2020 Wimbledon
Williams Sisters - I have to wonder if they'll retire at the same time.. I'll give them till 2017
