Predicted Winners in BOLD
ARTHUR ASHE STADIUM (11 a.m.)
 Rafael Nadal (ESP) vs Alexandr Dolgopolov (UKR) – Rafa has looked a bit vulnerable, but it is hard for me to see Dolgopolov winning 3 sets in this match.
 Roger Federer (SUI) vs  Philipp Kohlschreiber (GER) (7 p.m.) – Did Federer win on Saturday due to Lopez not having a great return of serve or did he win because he is playing better than he did in rounds 1 and 2? We will find out today.
LOUIS ARMSTRONG STADIUM
 David Goffin (BEL) vs Andrey Rublev (RUS) (not before noon) – Goffin has to love his draw, but Rublev is playing well.
 Dominic Thiem (AUT) vs  Juan Martin del Potro (ARG) – What a match! I think JMDP may be in Rio 2016 mode.
