I dislike Nadal's antics ( the stalling, time wasting, ass picking, etc. ) as much as anybody else,
but calling him a "cheater" is way over the top.
Just wish the ATP would be more consistent enforcing the rules, in particular regarding the times taken between points, and the challenges.
It really bugs me when a player, takes a stroll to the line, lokes at the line, then looks at his box, gets the go ahead from his folks, and then decides to challenge a call..
And gets away with it ! Ridiculous....
ON the other hand , today in the Querrey - Cilic match, Querrey wanted to challenge a call, had his hand up, but the umpire was not looking in his direction..
Several seconds later, when the ump finally realizes that Querrey wants to challenge, he decides that it is too late... Go figure....
