Sascha Zverev is apparently dealing with some injuries that are impacting his performance, as he was unable to get through David Goffin in the round of 16. To think that a potential Djokovic vs Zverev matchup is going to be an Evans vs Goffin showdown because of those two upsets is fascinating. But there is a reason that tennis matches aren’t decided on paper, and it is what makes the sport so enjoyable.
