Predicted Winners in BOLD
 Kei Nishikori (JPN) vs. Viktor Troicki (SRB) H2H – Nishikori has to be the pick, but legitimate questions can be asked about his durability. Did his deep run last week open a door for Troicki this week?
 Novak Djokovic (SRB) vs. Gilles Muller (LUX) – Novak has seemed a little off ever since winning Roland Garros. Perhaps Murray’s challenge to his number one ranking will reignite Djokovic’s focus. If so, Muller is in a bad spot.
 Andy Murray (GBR) vs. Fernando Verdasco (ESP) – These two have had some fun matches including their 2013 Wimbledon tilt. Andy could fall if the pressure of seeking number one gets to him, but I don’t think that will be the case.
 Marin Cilic (CRO) vs. Ivo Karlovic (CRO) – Ivo reached the Vienna semifinals and had a chance to reach the final. Cilic just won Basel. I’d advise fans on court one to take cover from some of the serves that will be blasted, but Cilic gets a slight nod based upon his well-rounded game.
 David Ferrer (ESP) vs. John Isner (USA) H2H – Ferrer withdrawing in the Vienna semifinal round raises enough questions about his health for me to consider Isner. The big man’s 1-7 record versus Ferrer including a loss at Bercy 2015 does not inspire me with enough confidence to actually pick Isner. John Isner’s volleying and backhand are not strong enough to put balls away versus a player who fights and moves like Ferrer. If Ferrer can run and grind, I think he will relish this challenge and add an 8th win over Isner.
