Think twice before you throw your racket!!!!

 

If you are playing a match against a traditional rival in your club, with that person who you can never win, and you lose a fundamental point of the match, the first thing you try to do is to throw the racket, after seeing this video you must think twice before you do that.
  
After seeing what happened to the German Anna-Lena Gronefeld, who was 14th in the WTA ranking and now she is number 252nd. Think twice before you try to throw your racket.
