Tears & tantrums from teenage brigade
It was a case of tears and tantrums on court number six at the Nasdaq-100 Open on Sunday.
Watching Vaidisova is a draining experience, with enough highs and lows to last an entire night in Miami's exuberant South Beach region.
She was ranting, shrieking (but not grunting) and then, after being broken for 6-5 in the second, came the sudden tears.
Her body was shaking and her face was buried in the towel.
When she rose from her chair, her face was cherry red, and the ballboy at the net - the only person face-to-face with her during the changeover - looked visibly shocked.
Tears in tennis have flown for years but to see them during a third-round match, in such an innocuous setting as Miami's Court Six, was quite perturbing.
After the match, she refused to shake the umpire's hand, annoyed at an incorrect line-call in the second set tie-break, and stomped off the court.
