Predicted Winners in BOLD
 Jack Sock (USA) vs.  Ivo Karlovic (CRO) H2H – Jack should win so long as he returns well and/or plays well in tiebreaks. I am not sure that will happen. Ivo just won a tournament and has the advantage of knowing exactly what his game plan is.
 Gael Monfils (FRA) vs.  Sam Querrey (USA) H2H – Their first and only match was a close straight set win by Monfils on clay in 2007. Both are playing well. I think Sam finds a way if solely because Isner has had nice results vs. Monfils. Querrey is coached by Isner’s former coach so his game plan should be solid.
