Norrie will be really disappointed at losing that long first game on serve. He needs to keep his energy up and cannot afford to be giving cheap points away.
*Schwartzman 6-3 6-4 2-6 1-6 1-0 Norrie
Norrie keeps the pressure on and it pays off as Schwartzman's shot lands on the wrong side of the line. Deuce.
This is going to be a lengthy fifth set...
*Schwartzman 6-3 6-4 2-6 1-6 1-0 Norrie
A three-hour, five-set epic is exactly what you need after months away from elite tennis...
Whoever does make it through is going to be feeling this in the second round. It looks like every game in the final set is going to be a battle as Schwartzman claws his way to a 30-15 lead.
*Schwartzman 6-3 6-4 2-6 1-6 1-0 Norrie
Schwartzman has done an amazing job to turn things around early in this final set.
Norrie cannot close out the game and his backhand lands long to give the ninth seed his break.
Schwartzman 6-3 6-4 2-6 1-6 0-0 Norrie*
Norrie keeps his composure and builds a point well, forcing Schwartzman to hook his backhand wide. Break point saved.
He battles hard for the next point but his forehand lands long and it's another break point - the 40th of the match.
Norrie saves it with an ace again as the clock edges towards three hours.
Schwartzman 6-3 6-4 2-6 1-6 0-0 Norrie*
Norrie saves another break point chance. Is every game going to be like this in the fifth set? Not sure my nerves can handle it.
The 25-year-old doesn't get his feet round a forehand and it lands out. Yet another break point for Schwartzman.
Schwartzman 6-3 6-4 2-6 1-6 0-0 Norrie*
Norrie saves the break but immediately gives another chance away with a double fault.
He's not cracking under the pressure though as the Brit lays on another ace.

As well as Schwartzman getting rattled, another factor which has helped turn the match in Norrie's favour may well be the Briton's match practice this summer.
Norrie played in several of the LTA-organised exhibitions and that could benefit him as he takes this one the distance.

Ace=deuce.
But then Norrie comes forwards and misses the volley. Another break point.
Schwartzman 6-3 6-4 2-6 1-6 0-0 Norrie*
It feels like there's not going to be much to separate these two in this final set.
Norrie knocks a forehand into the net to bring up 30-30.
He's not too quick on his feet running backwards and the resulting mishit forehand goes long. Break point Schwartzman.

Cam Norrie has only won one five-setter before... and you may well remember that one.
That came on his Davis Cup debut for Great Britain against Spain in February 2018, when he also fought back from losing the opening two sets to beat Roberto Bautista Agut.
Now Norrie is well in the ascendancy here as he looks to stick another famous win in the long-term memory bank.
Schwartzman 6-3 6-4 2-6 1-6 0-0 Norrie*
Right Schwartzman has changed his top to a blue one to a red one. He means business now.
But he berates himself as he swings a forehand wide. It's almost as if the colour of your shirt has no bearing on your tennis.

It's very un-Schwartzman-like - he's such a difficult player to break down. For all that Cameron has played well, Schwartzman has given him an awful lot. Like that last shot - for the number nine seed that is not really acceptable.
Schwartzman 6-3 6-4 2-6 1-6 0-0 Norrie*
Here we go then. The decider.
It looked like the kind of straightforward win that a ninth seed would usually enjoyed in the first round but Norrie very much looks on course for a comeback now.
He's been getting more and more confident over the last couple of sets and Schwartzman has looked more and more downtrodden.
Schwartzman 6-3 6-4 2-6 1-6 0-0 Norrie*
Seriously impressive from Cam Norrie.
It's such an anticlimax without fans. Schwartzman's forehand lands wide and where you would expect wild screams as we're on the brink of a first-round five-set comeback, there is only silence.
Norrie still looks pretty happy with himself.
*Schwartzman 6-3 6-4 2-6 1-5 Norrie
Wow. A third double fault. Set point Norrie.
*Schwartzman 6-3 6-4 2-6 1-5 Norrie
ANOTHER double fault and it's deuce. The ninth seed really looks to be struggling now.
*Schwartzman 6-3 6-4 2-6 1-5 Norrie
Looks like Norrie might have to wait to seal this set. His forehand slams into the net to put Schwartzman 30-0 up.
But a double fault from the Argentine gives Norrie a chance, levelling things at 30-30.
*Schwartzman 6-3 6-4 2-6 1-5 Norrie
Norrie closes down that chance with an ace out wide.
A poor return into the net gives the Brit a helping hand. After a few visits to deuce, Schwartzman swings a backhand wide and looks disheartened as he plods to pick up his towel. Norrie holds.
A fifth set and possible upset is surely incoming now.
