Kyrgios N. vs Nishikori K. prediction

Personally, I pick against Nishikori who should be exhausted after recent match against Monfils. Both of them played very tough match. Japanese won thanks a lot of luck and a lot better mentality too. At key moment Monfils choked what cost him a match. He had 6 match points in 12ve game in 3rd set, and of course waste all of them. Nishikori used to endure rahter poorly phisically so I take Kyrgios side as he looks sharp and fresh. Kyrgios with no sign of tiredness.
