Looks like Isner is running out of gas and his legs are wobbling as he just seems to be swinging his racket around wildly as if swatting at flys. I will give my expert prediction as soon as my houseboy brings me my Top Ramen noodles.
Yep, sure looks like that young Palooka from Italy is giving Isner a well deserved thrashing and I'm sure Diego agrees with me as he has done before so many times in the past.
I get them wrong as well 😉
