Predicted Winners in BOLD
 Grigor Dimitrov (BUL) vs. Ryan Harrison (USA) – Harrison is 1-3 vs. Dimitrov, but has played well enough in 2017 that he could spring an upset here. I think Dimitrov will come through in 2 competitive sets.
 Alexander Zverev (GER) vs. Aljaz Bedene (GBR) – The big man should advance here. Tennis needs someone to step forward and become a general threat to win any match/event on tour. Zverev seems to be close to this point, but he is not there yet as evidenced by his 1-2 record at the US and French Opens this year.
 Rafael Nadal (ESP) vs. Jared Donaldson (USA) – I don’t think Rafa is playing the best tennis of his career, but there are few on tour with the weapons and willingness to take him out of his comfort zone.
 Roger Federer (SUI) vs. Diego Schwartzman (ARG) – Roger should win this encounter.
 Sam Querrey (USA) vs. [Q] Frances Tiafoe (USA) – I nearly picked Tiafoe. Querrey has a 9-2 record in his past 2 majors. That is a feast after many famines in US men’s tennis.
 David Goffin (BEL) vs. Gilles Simon (FRA) – These two have some similarities. I think Simon counter-punches and retrieves more often than Goffin, but when Simon is at his best he also takes the ball early. This could be a fun match if Simon is on his game.
 John Isner (USA) vs. [Q] Stefanos Tsitsipas (GRE)
 Dominic Thiem (AUT) vs. Viktor Troicki (SRB) – See what I said about Zverev. Tennis needs Thiem to be a consistent threat on surfaces other than clay (if possible).
Feliciano Lopez (ESP) vs. [Q] Alexandr Dolgopolov (UKR) – If Lopez can knock off enough volleys, he should win.

Steve Johnson (USA) vs. [WC] Di Wu (CHN) – The moustache pushed Kyrgios off the deep end.
 Kevin Anderson (RSA) vs. Jan-Lennard Struff (GER) – Anderson should advance.
