I know about that..did he win that match??
You know he should do it more...for his own good...and put on some muscle..
Nope, that was against Tipsarevic in Miami last year. He lost 3-6 6-7.
I've never been a fan of breaking the rackets. Throw one in the stands if you don't feel like using it anymore, and heal your frustrations elsewhere.
But yes, he should be showing more emotions. Apparently he did gain some muscle during the time he didn't play.
