Ramos A. vs Nishikori K. prediction

The first match for the Olympic Games in this sport will be between Ramos (no. 33 ATP) and Nishikori (no. 6 ATP). In their history, this two players met four times in a direct confrontation: three time on clay and one time on hard. Ramos is a player that play better on a clay surface but the only set taken from Nishikori was on a hard surface in Malaysia 2012. Nishikori is trying for a long time to be in top 3 players of the World but it's hard because he met for five times Djokovic in direct confrontations just this year and we are in August. He is very confident because excluding the last match against Djokovic when he lost with 6-3 7-5, he won against Wawrinka with a comfortable result 7-6 6-1. On the other side, Ramos was unlucky playing against one from the top 10 player in ATP standings but I think he will not give up so easy and we will see more than 19.5 games. It's not excluded to see more than 2.5 sets but I will take an over 19.5 games for this match.
