Here's how the quarterfinals break down: John Isner vs. Tomas Berdych, Rafael Nadal vs. GrigorDimitrov, David Ferrer vs. KeiNishikori and ​Andy Murray vs. MilosRaonic or Leonardo Mayer. With Roger Federer's opening round loss to Nick Kyrgios on Wednesday, Murray is now the top seed remaining.

This is great counter-punching and defense from Caroline Wozniacki, as she defends until she finally gets a ball she can do something with:
