Not sure why but I voted Cilic in 5. I actually think Murray will win & get revenge of sorts for the USO. Will be interesting to see if Murray can keep his level up & not have a let down seeing as he's clear favourite to get to the final (he's in great form, beaten some top players already, not dropped a set, Cilic has had to expend a lot of energy already etc).
Could see him losing a set but I don't seriously see him losing the match. No explanation then as to why I voted Cilic in 5, maybe just wishful thinking
