And this has been the problem for Nadal for the last couple of years. He just can't seem to close a match after winning the first set. Now, he has given Raonic some life now...
As for the 3rd set, I give the edge to Nadal just because he has been reading Raonic's serve very well except on very crucial moments.
However at the same time, Raonic's serve is still pretty big so anything can happen...
