The Australian Open -- crazy on both sides, with top seeds falling regularly. Djokovic AND Murray out? Unthinkable. But that's what happened. Smart money would be on Wawrinka now, but with Federer and Nadal still in it, anything can happen. And is it Grigor Dmitrov's time? Probably not, but it seems like it's still slightly possible.
On the women's side, Kerber was eliminated, Halep (sob) was eliminated, and so was Radwanska. (Those latter two need to win a major.) Wozniacki was eliminated right after feeling good about where her game was.
The unexpected player playing great is Johanna Konta, who is going to be playing Serena Williams quite soon. So here's my quick prediction: whoever wins that match will win the tournament.
