When considering Murray's H2H versus the top guys I believe it is the very worst against Rafa! He's at 5 wins in 18 tries. So unless you're a Rafa fan, not sure why you'd be stoked for a Murray/Rafa final. Ha ha.
But seriously, I do hope Andy starts to turn around that H2H with Rafa. It's too lopsided.
Because the H2H is skewed mostly down to Andy's belief rather than his game, because when they last met Andy destroyed Rafa after a slow start (3-6, 6-2, 6-0), because Andy has improved dramatically since then, because Rafa isn't at his best right now, because Andy's should now have the belief that he can beat Rafa.
I would love to see Murray play Rafa, not least to see how he will fare now having not played since USO 2011. It's an enjoyable match-up.
