I thought I had seen Sandra Zahlavova play before. I hadn't. Straight from the Michelle Larcher de Brito school of on court decorum I'm sure there were calls made to emergency services reporting that someone was being slaughtered. Venus Williams is known for being vocal on court (she's not in the league of de Brito or Victoria Azarenka though) so things were pretty loud on court. It says something when a long time tennis viewer like me can actually tune out the audio and watch the tennis.
