Predicted Winners in BOLD
Philipp Kohlschreiber (GER) vs. [Q] Pierre-Hugues Herbert (FRA) – Kohlschreiber should have some momentum after his win over Isner.
Fabio Fognini (ITA) vs. Diego Schwartzman (ARG) – Fognini has the higher ceiling but also has the lower floor.
 Jo-Wilfried Tsonga (FRA) vs. Karen Khachanov (RUS) – Tsonga has some momentum after last week.
 Alexander Zverev (GER) vs. Gilles Simon (FRA) – Simon will need to hold serve frequently to make this into a match.
Damir Dzumhur (BIH) vs. [SE] Ricardas Berankis (LTU) – Damir Dzumhur has had an excellent few months. I think that continues.
#Zverev in Vienna: “I feel comfortable playing indoors. I won 2 tournaments indoors. I just needed to get used to the conditions again.” pic.twitter.com/7ZBMaGhtwV
