Kyrgios's serve is unbreakable right now whereas Murray's been broke 3 times already. In today's post-match interview, Kyrgios emphasized that he wanted to do as little running as possible today. Plus, he got a break in an early retirement from Fucsovics. I think Kyrgios is giving it his all this week on his most habitable surface. Add to that the fact that he typically shows up against marquee players like Murray. I'm ignoring the head-to-head here. At worst, Kyrgios loses 6-7, 6-7. I'll take the juicy odds.
