I agree with you.......tooooo much.
Then add 3 matches to Qualify for the Main Draws,and you've got the perfect recipe for injuries and burnout before the US Open.
I guess the players have to be wise enough to backoff from some of the Tournaments in the "Series",and only choose a few.
Maybe that's what Agassi is doing.
Let's not forget that Men's Pro Tennis is run by the Sponsor's,not by the ATP or the USTA.
