Rafa Nadal has gotten through his Australian Open quarter-final this morning in four sets, 3-6, 7-6, 7-6, 6-2, and it included this brilliant rally between himself and opponent Grigor Dimitrov.
Keep an eye out for Dimitrov's brilliant through-the-legs lob.

Speaking of great rallies, this one between Agnieszka Radwanska and Victoria Azarenka wasn't half bad either.
