Kei Nishikori vs. Tomas Berdych

Neither guy showed a lot in their first match so either could be ripe for a one-sided loss.  Nishikori holds a 3-1 head-to-head advantage, but they have not played since 2012.  I think this match comes down to health and to recent form.  Nishikori does not seem to be playing well as of late. Rumblings were that he is not healthy during his match versus Djokovic.  I am not sure when Kei is ever 100% according to experts or his camp, but I think his form and fitness are a factor.  Berdych can win so long as he backs Nishikori off the baseline.  If Berdych’s serve and returns allow him to push Kei backwards, I think Berdych wins pretty easily.  If Kei can stay on top of the baseline or inside the baseline, he will rob time from the Big Czech and have a great chance at victory.  Based on recent form, I think the former is the more likely scenario.

My Prediction: Tomas Berdych d. Kei Nishikori 7-5, 6-3
