Didn't see the whole match, but from what I saw, Humbert played well and Isner was really poor, maybe the American suffered from a cold - he showed some signs of that at least (like holding his hand against the nose before serving a couple of times). Isner's stats on return was bad, even for his standards. Humbert lost only two points on serve in the second set and went 38 out of 38 on first serves for the match, that is Isner didn't win a single point against Humbert's first serve. And it was not like Humbert was serving out of this world, he only hit four aces for the match. But anyway, the young Frenchman played well, and no doubt he has a shot at his maiden title, no matter who he gets in the final - Paire or Hurkacz.
