Re: Cristina Dinu
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.
