The most realistic will win.

Jarry should have lost against Mannarino and the same observation for Humbert vs Giron but both were realistic and excellent on the important points.

Jarry had a hard time against Mannarino, in the service he was calmer when his first pass but in the game he had a lot of difficulty against a compact and good Frenchman. Humbert is a bit of the same profile, already he is left-handed but with his flat backhand and his ability to hold his line it is essentially the same match that awaits Jarry. When we see how he struggled we can wonder if it will work this time. Humbert also had a hard time against Giron and even saved a match point, he was good at serving though. A match up not necessarily to Jarry's advantage, if his first ball does not pass I give the advantage to Humbert in the exchange.
