Predicted Winners in BOLD
ARTHUR ASHE STADIUM (Noon start)
 Rafael Nadal (ESP) vs Andrey Rublev (RUS) – Nadal is likely to beat Rublev who should be proud and thrilled with his quarterfinal finish.

 Roger Federer (SUI) vs  Juan Martin del Potro (ARG) – I expect a great match. I think Delpo’s more slice based backhand will be good for Federer. Still, Delpo’s forehand, his serve, and his will power all give him a great chance. Federer has looked much better the previous two rounds, but how much mentally is left for him in 2017 after winning Wimbledon and the Australian Open? I think JMDP rides the wave of his comeback win and hits enough good backhands to advance in 4 or 5 sets.
