Taunting the opponent with inyourface ajdefistpumps is her gamesmanship of choice, the problem is it doesn't work anymore, she needs a new one.
I have to write a longer respond to this.
I'm extremely annoyed by Azarenka's celebrations and Kvitova's barks, so I understand why you dislike Ana's ajdefistpumps. But a pro tennis player should know better than to get upset. It is psychological and they do it to put their opponents down... Ana, Vika, Serena, Maria, Kaman, Petra, Pome, Batoli, Makiri... Novak, Tsonga, Rafa, Monfils, Hewitt, Tipsy... But it's up to their opponents to respond to that. It's like challenging someone.
Honestly, if a guy complained about the fistpumps, he would be mocked for that. But Tsonga says we're all mentally unstable, so JJ can say she was distracted by fistpumps and get away with that. She did so much damage to herself mainly because she's always distracted... By fistpumps, ballboys, her hair, her nail, someone in the crowd, court #17 on Wimbledon... She simply gets involved in some drama that only exists in her head.
It's like when Myskina was distracted by JJ's "strange behavior".
