Predicted Winners in BOLD
 Rafael Nadal (ESP) vs.  John Isner (USA) – I don’t think Rafa enjoys playing Isner much. Rafa wins two ways: excellent play and grinding his opponent’s mental and physical game down. Isner hits so many aces that this grinding style doesn’t impact him as much. Isner led 2 sets to 1 at Roland Garros. Isner lost 7-6, 7-6 to Rafa in the 2013 Cincinnati final. Isner beat Nadal at the Laver Cup (non sanctioned) recently. I think Rafa wins, but a loss would not be shocking.
 Alexander Zverev (GER) vs. Andrey Rublev (RUS) – A
n all-Russian battle err a German-Russian battle.
 Grigor Dimitrov (BUL) vs.  Roberto Bautista Agut (ESP) – Grigor needs to end the year strong for 2017 to be seen as more than an odd year for him.
 Nick Kyrgios (AUS) vs. [Q] Steve Darcis (BEL) – Kyrgios throws some power and then more power to win this match.
