Novak Djokovic -06- (SRB) def João Sousa -68- (POR) | 63 64 63
Who is João Sousa? Popular question in Arthur Ashe Stadium before today’s thickly humid Round of 16 match. Quick answer – he’s the best Portuguese player in tennis history. And thanks to back-to-back top-20 victories last week, he reached Round-4 of a Major for the first time.
Now that we’ve handled the introductions, let’s walk through Novak’s dismantling of the World #68…
Behind a pair of breaks, Novak took set-1. After a sloppy service game in the second, Novak broke right back and ended set-2 with another pair of breaks. He delivered his 5th break late in the third to serve out the match and return to the US Open Quarterfinals.
Routine? Not according to the 2-time champ (2011 | 2015). During the winner’s interview, Novak said he can “feel his biological clock ticking,” as he continues to battle this year’s insane humidity as much as his opponents.

Ranked as high as world #28, he is the first player from his country ever to win a Tour-level title, and the highest-ranked Portuguese player in tennis history.
