In Nashville, Ruben (ATP-110) is the strongholder of the Belgian Davis Cup team. On Friday, he faces Sam Querrey (ATP-14) in the second match.
Joris De Loore (ATP-319) opens the debates on Friday against John Isner (ATP-9). After that it's Ruben's turn, who has to face big serving Querrey.. The American won their previous encounter in Nice in 2015.
Nevertheless, Ruben remains positive: "I definitely believe in an update, I have reached a reasonably high and constant level in the last few months. The key will be that I won't let him dominate, that will certainly be difficult with his big serve. I will need to stay aggressive, so he can not dictate the rallies. Three years ago I played against Querrey in Nice, that will certainly help me. He is a big player, but that also makes him a slower mover on the court. I need to keep him running, I know that he will hit a lot of aces, so I know what to expect."
