Arthur Ashe rolling in his grave...
First some facts:
Serena herself said in the post match she thought she had committed a foot fault.
Nobody threatened to kill anyone. Serena said in the post match that she (when she was standing up at the umpire's chair afterward) had misheard what the linejudge was claiming she (Serena) had shouted. The "kill" rumor is now unleashed on the internet all because of...Serena. Again, the girl may indeed have enemies, but her biggest one is her own mouth.
Line judge was at least a foot smaller than Serena who charged over to her wielding a racket...just like the one she had earlier smashed into the ground (getting the first warning). Serena's language (and body language) was clearly that of someone out of control and I was actually afraid watching (live) that she was going to attack her.
The line judge went back to her position until the umpire called her over to ask what had transpired. If she was smiling, it was a very nervous kind of smiling...as in "I can't believe what is happening here, I'm not sure how to react."
In a bit of hilarity, McEnroe blurted out that the line judge couldn't possibly have determined whether it was a foot fault from the position she was standing in. Ironically, she was actually the only one aligned with the baseline and was the ONLY one able to make the call. That's kind of why they put a judge along that line Mac. The footage is all from behind the baseline (as was McEnroe's angle).
Serena's losing the match was not the result of one misstep...it was the culmination of a number of things. She looked like someone deliberately out to create some distraction (when her racket didn't break the first time, she picked it up and whacked the ground again...until it finally broke...mature professional that she is).
Serena behaved like thug. She was not in any way a victim of racism (although I'm sure her behavior will inspire a lot of racist commentary). She was playing in Arthur Ashe stadium (google him you nitwits). Ashe was known as above all a gentleman. He was passionate, sometimes fiery but always classy. Serena unfortunately is a very poor heir to his legacy. She ruined that match for herself, for the fans, and most of all for her opponent (who looked stunned and sad).
Serena is an embarrassment to American tennis and she should not be allowed to play in the doubles final. Maybe when she sees that her behavior has cost Venus as well, she snap out of her pathological selfish arrogance.
