Predicted Winners in BOLD

(4) Dominic Thiem VS (6) Grigor Dimitrov – The surface favors Dimitrov, and Thiem has had a forgettable post-Roland Garros season.

(1) Rafael Nadal VS (7) David Goffin – Rafa had some injury issues in Paris.  Goffin has played quite well this fall.  If Goffin can take the ball early on his returns and pressure Rafa’s serve, this could go either way, but I think Rafa wins.
