IIRC in that Petkovic match, Andrea was sick and had informed the umpire that she was gonna request the trainer to come during the next break. So her running out of the court wasn't that unexpected. But I agree that Radwanska (it was her opponent if I'm correct) should have been awarded the game. A similar incident happened with Ivanovic who took a (bathroom?) break out of the blue and when she came back the umpire told her that all the points that should have been played while she was away were given to her opponent.
Anyways, she's in Sofia this week. Hope she does better

Wow, what has happened to Kolar? She played WTA events at the age of 16 and looked like a lock for the Top 100 in a couple of years, but she is stagnating badly.
Well, not as bad as Elena Bogdan, but disappointing as well.
That one match in Bad Gastein where she wasted tons of MPs smacking one racket after another.
I watched that because I was bored in summer back in the day. I haven't seen such a nutter since.
She never fully recovered, might be a case for the 'one point which changed everything' thread on GM now.
