It was another scorcher at the Australian Open and for the second day in a row, a French player bore the worst of it then took aim at organizers.

Wozniacki trailed Jana Fett 5-1 in the third set and stared at two match points on the Croatian’s serve before winning six games in succession to move into the third round 3-6 6-2 7-5 on an eventful Wednesday in Melbourne where temperatures exceeded 30 degrees Celsius.

But that’s nothing compared to Thursday and Friday, when the thermometer is expected to hit 39 degrees.

Djokovic spent as much time in his post-match media conference discussing a players’ meeting last week, one in which he reportedly said that the players should seek more prize money at grand slams and set up a separate players’ union.
