Re: Australian heat wave.
Serena plays well in heat. Kerber seems to do well too. Li is a home player. Petra probably won't play so well. Sharapova is hit and miss. Errani, meh. Stosur doesn't play her best in Australia. Caroline forget going very far the way she's playing now let alone in 40C.
Vika is the big question.
Vika will faint like she used to 2-3 years ago
