Schwartzman 6-3 6-4 2-6 1-4 Norrie*
In the absence of fans you can really hear play on the other courts and someone is doing a lot of screaming. It's creating a weird atmosphere but Norrie is in the zone.
He bashes a forehand winner out of Schwartzman's reach to bring up game point. He catches the ball on a funny bounce, though, and it's deuce.
Schwartzman 6-3 6-4 2-6 1-4 Norrie*
Norrie is ranked 76th in the world; Schwartzman is 13th.
But all the momentum is with the 25-year-old Brit as he steps up to serve.
He's caught on the back foot on the baseline and loops a forehand long. Another unforced error from Schwartzman gets Norrie back on track though as the ball flies into the net. 15-15.
Schwartzman 6-3 6-4 2-6 1-4 Norrie*
He only needs one of those break points. The ball kicks up high and Schwartzman is caught off guard, nudging a forehand long.
He's still got a couple of sets to win but is Norrie on the way to a big upset against the ninth seed?

I'm with Judy Murray on this one (as if you'd dare disagree with her on all things tennis) - Schwarzman is definitely out of sorts.
A couple more unforced errors give Norrie a 30-0 lead.
*Schwartzman 6-3 6-4 2-6 1-3 Norrie
Norrie steadies things with a steaming forehand winner and his serve out wide is too much for Schwartzman. The Brit holds.

That was tremendous from Norrie. Schwartzman is really out of sorts, something has really grumped him. Long may it continue for Cam's sake!
Cameron is getting a lot out of Schwartzman's backhand. He is looking very strong now, so as long as Schwartzman continues in this mood he's in, it's all good for Cam.

Schwartzman powers up for a huge cross-court backhand, but there's a bit too much power on it and it lands wide leaving Norrie with two break points.

Norrie's first serve down the middle is almost a winner. But not quite, it lands out.
He still manages to save break point though as Schwartzman's second-serve return goes into the net. If Norrie is going to mount a comeback, he absolutely has to hold this game.
An ace helps him along the way.

*Schwartzman 6-3 6-4 2-6 0-0 Norrie
Cam Norrie bounces back to the baseline. he looks up for this.
Schwartzman has a decidedly darker look on his face.
But it's the Argentine who wins the first point with a smash from behind the baseline.

Schwartzman definitely let Norrie back in a bit with the argument with the umpire and the time violation. And Cam just managed to fix those problems on the break points.

Norrie sorted out his unforced errors in that third set. Five compared to 17 in the second set and he hit 12 winners.
