You better find other sources, Mary is one of the most popular player on tour LOL
Sportmanship !!! you know that only people on this board are talking about Mary's habit as a "tactic"
About US Open "12 minutes thread" even journalists are making fun of Elena's reaction, and you know why, it's because Mary had the right to do it and in fact the WTA physio told Mary to take this timeout.
Mary has habit like Henin, Nadal, or Federer when he's upset....each player has some habit but sometimes you don't pay attention or don't see it, did you know Martina didn't want to walk on the line when she finished a game, see what I mean
Mary LOL you can tell when she is under pressure, ponytail, ball (more and more time)... Elena well more and more doublefaults, it's different but it's habit too
Like I said somewhere on this board, it would be awfull to see all the player with same reactions, habits or whatever you call that!
Mary is one of the best player of the open area, I say it, journalists say it, professionnals say it, so forget about this "tactic"
Let's tennis players play and enjoy
