*Schwartzman 6-3 6-4 2-6 1-6 4-3 Norrie
Schwartzman has called for a physio to come to the court. Maybe it's something to do with his fall earlier. It might be some clever tactics but who are we to judge?

Schwartzman has called for a physio to come to the court. Maybe it's something to do with his fall earlier. It might be some clever tactics but who are we to judge?
*Schwartzman 6-3 6-4 2-6 1-6 4-3 Norrie

Fifty break points clearly is not enough for these two. Schwartzman is on his way to another as Norrie taps the ball into the net and the Argentine goes 30-0 up.
Bit greedy if you ask me.

Norrie had success with the drop-shot in the third and fourth sets but the drop-shots here weren't quite good enough.
*Schwartzman 6-3 6-4 2-6 1-6 3-2 Norrie
This has been so impressive from Norrie, taking it to a fifth set.
But can he close it out when he's a break down in the decider against the ninth seed? Quite tricky that one.
*Schwartzman 6-3 6-4 2-6 1-6 3-2 Norrie
A series of sublime backhands saves the first break point for Norrie.
A less impressive Schwartzman backhand, which lands in the net, saves the second.

Who wants a remarkable stat? There have been 45 break points (FORTY-FIVE!) so far in this match.
That can't be far off some kind of record, surely.
Norrie has won eight of 25 (32%) and saved 15 of 21 (71%).

That is a huge game to break for Cameron - not only for his confidence levels but for his energy, to know he is still in this match.
The energy levels are the difference between them at the moment. They are moving similarly at the back of the court but Cam is just bringing a bit more energy.

Surely not, could this be a straightforward hold for Norrie?
We're yet to see one in the fifth set but the 25-year-old is quickly up to 30-0 after a couple of well-constructed points.
Then he undoes it with a double fault. Sigh.

Finally! The first two games in this set have been around the 10-minute mark and neither player really has anything to show for it as we're back on serve.
Schwartzman hits a backhand into the net, Norrie celebrates.
*Schwartzman 6-3 6-4 2-6 1-6 1-0 Norrie
It feels as though Norrie has to win this one.
Schwartzman gives him an opening with a double fault. Both these players are getting pretty tired now.
Norrie comes to the net and it doesn't work so well this time as he taps a half-volley long. Deuce again.
*Schwartzman 6-3 6-4 2-6 1-6 1-0 Norrie
But it's break point squandered. The error count is stacking up on both sides of the net. Norrie goes down the line and it's nowhere near in. Deuce.
