They always said Murray had a deceptive speed about him. However, I don't know if it's this year or what, but the guy looks about as fast as anybody on tour in regards to movement around the court. Perhaps even as fast as Nadal & he moves perhaps more efficiently also. This is not a post to question where this newfound speed came from. Perhaps he's just been really hitting the gym hard. Or perhaps he's just maturing physically & naturally getting faster. It just seems like a huge jump in improved athleticism. What do you guys think?
