When did Wawrinka serve this good??

[beefcake]

Fukkstick is going to have over 30 aces..time to bet him over FED!!

[Sharapova]

Idk but I saw yesterday vs istomin. It's a weird looking serve, not a high toss and he hits it fast as hell when he tosses it up

[brodie]

i was just watching the live score a minute ago on my phone and it said he was serving consistently around 129mph on his 1st serves... that's pretty good for stan

Lopez choking bitch I think shittypova lose

Stan was blowing it by Istomin, when Istomin started feeling better, there was still nothing he could do
