Predicted Winners in BOLD
Center Court (11 a.m. start)
 Grigor Dimitrov (BUL) vs. Juan Martin del Potro (ARG) H2H – This should be a fun match. I lean slightly toward Dimitrov because I always have concerns about JMDP’s wrist and backhand. Still, I think JMDP is the mentally stronger of the two.
 John Isner (USA) vs. [WC] Frances Tiafoe (USA) H2H – Isner won 2 events after Wimbledon (Newport and Atlanta), but I still favor Tiafoe to pull off an upset. I think the younger player can feel confident about holding his own serve versus Isner, and this will allow Tiafoe to get any kinks out ahead of a 1st set tiebreak.
 Rafael Nadal (ESP) vs. Albert Ramos-Vinolas – Rafa tends to punish his fellow Spaniards. I don’t think AVR will be over-awed, but I do think Rafa has more game.
