Hope mischa wins. But querrey is on fire.

Come on the good Zverev

Only American (male) player with a Backhand and easily the most enjoyable

Could be tough but I have mischa in four or five

Like Johnny Mac said, he must've hurt himself when he looked up at the score. Lol!!

Sammy you're my hero.
C'mon now!

USA needs a tennis hero and that's Querrey.

Damn, I Really like the two of them. Oh well i guess I don't mind who wins.

Come on sam, bring us that trophy

Let's go sam!!! :):):)
Last American standing :)

Sammy's the best American male player we have.

He's always been underrated.

It's surprising when u think Querrey is playing on Arthur Ashe for the first time.

Sammy is the real deal! ;)

USA! USA! USA!

Heard those stats and was amazed too. Sammy is the new real deal. Sammy all the way!!!

Yeah if there's one thing Sam's improved it's his mental toughness. Saw him at Wimbledon against Murray and that match is a clear example

Sam will definitely win.. Semis in Wimbledon n finals in us open .. Go sammy

Pretty much same match for Mischa except the fact that this American is a much better baseliner

From the US open website - where you can't post comments ...
"To reach further, Querrey will need to get past Zverev, who’s enjoying his best-ever run in Flushing. A quarterfinalist at January’s Aussie Open – where he beat both John Isner and Andy Murray – the 30-year-old Russian plays a throwback serve-and-volley style with incredible precision. In his win Friday night over Isner, Zverev posted an impressive 34 winners against a ridiculously low seven unforced errors."

Mischa Zverev might be born in Russia and his parents played for USSR but he is GERMAN, as far as I know by ethnicity (yes there were and still are many ethnic Germans in the former USSR) and passport.

Cmon SAAAAAAAM!!!

Sam returns way better than isner ever has

I believe he can jason.

Querrey passing shots are super impressive considering Mischa is one of the best on the net right now

I think Sam's just overall better than Kev, I'd say Sam in 4

Looks like mischa is playing with an injury, no?

no matter...sam can beat anyone when he's playing like this :)

Mischa won't ever win a Grand Slam but he can make sure his brother does by teaching him the ABC of volleying

Sammy, Sammy, he's my man if he can't do it, no one can! :p

Yessss! 2 sets in 55 minutes!!

I'm listening to Johnny Mac, Chris Fowler and Brad Gilbert.
