Will Hurd, Stafford McDowall, Darcy Graham, Josh Bayliss and Jamie Bhatti cross for Scotland, in addition to penalty try
Luka Begic and Samuel Marques score Portuguese tries
Scots complete series against Australia on 24 November
Arron Reed
This time, Scotland's throw is better and they use the backs.
Adam Hastings whips a long pass out to Tom Jordan, who leaps to gather and slings another huge ball to Reed on the wing.
Given a few yards to burn, he speeds over in the corner. No second invitation needed.
Scotland 38-14 Portugal
Scotland win a throw but Paddy Harrison chucks it away - his third loss today. The hosts' set-piece is faltering big time.
George Horne is then thrown around like a rag doll by Pedro Vicente and immediately replaced by Jamie Dobie.
Elsewhere, Matt Currie is on for Rory Hutchinson - he impressed today.
Scotland 38-14 Portugal
This is the biggest points tally Portugal have ever scored against one of the home nations.
That might worry Gregor Townsend, and defence coach Steve Tandy, just a little.
Portugal are enjoying a good spell in Scotland territory here, and now they have a scrum on the 5m line.
The scrum crumbles, and Portugal get another chance.
They'll do so with an entirely new front row. Abel da Cunha, Pedro Vicente, and Antonio Prim enter, and immediately pulverise the Scottish pack.
Samuel Marques grabs from the back and plunges over the line.
Scotland 38-7 Portugal
Portugal disguise their throw and Nicholas Martins leaps forward to get the ball. Was he taken in the air, though?
No, play goes on. Scotland are living very dangerously here.
Scotland 38-7 Portugal
Time off.
Portugal were breaking, Darcy Graham stuck out a hand and knocked the ball on. Was it a deliberate knock on? Did it stop a try-scoring opportunity?
No, says referee Takehito Namekawa. Just a penalty.
Scotland 38-7 Portugal
Scotland go to the bench for the first time, replacing their try-scoring props and lock Alex Craig.
Rory Sutherland, Elliot Millar Mills* and Ewan Johnson are on.
*The tighthead has Millar-Mills on his shirt, with a hyphen. I'm sure he's said himself there's not one. We'll bring you more when we have it.
Scotland 38-7 Portugal
Darcy Graham is back to his feet and almost put away on the wing by a flat Rory Hutchinson pass - but no luck, as it's ruled to be forward.
A very similar feel to this second half as the first. Messy, little cohesion, and little consistent quality.
Scotland 38-7 Portugal
Darcy Graham is smashed again on the near side, and stays down. Will that try record evade him today?
Possession continues to change hands quickly and Scotland's ill-discipline haunts them again as Portugal win a penalty and kick into the 22m.
Jamie Bhatti
George Horne steals the ball and hares away from a few Portuguese defenders, can he make it all the way to the line?
No! He's hauled down a few yards short. Arron Reed tries to go over but he's held up too.
A few phases later, Bhatti goes over and Scotland have their sixth.
A first Scotland try for the loosehead prop.
Scotland 33-7 Portugal
And we're back for the second 40 minutes, as the sun sets on Edinburgh.
I'm sure it won't be long until we see Freddy Douglas - some of us for the very first time.

Chris Paterson
Former Scotland international on Sportsound
There were three or four interceptions [before Stafford McDowall's try] which was symptomatic of the game.
Scotland got control of the game by giving Portugal the ball and saying 'you do something'. Ten or twelve phases of defence brought a structure and a calm to their play.
Scotland look for that ball out the back too often, they're trying to do something too complicated.

Peter Wright
Former Scotland prop on Sportsound
It was a little bit disorganised, but there was enough to see when Scotland got it right, they got there.
A lot of Scotland's play was down to Portugal's line speed, their defensive shape, they didn't commit too many to the breakdown.
They've missed something like 19 tackles but it doesn't seem like that, it looked like they were nailing their tackles.
But they've tired and Scotland started getting through.

Tom English
BBC Scotland's chief sports writer on Sportsound
For much of the game, it was frantic and a total mess.
There was no shape to it, it was like a bad basketball match. It was all over the place.
Scotland will probably get another five or six in the second half, but it's not been hugely impressive so far.
Plenty for Scotland to think about after that first half.
They've got five tries to their name, but for spells they found it very difficult to break down the visiting defence.
They just didn't show the kind of cohesion Gregor Townsend asked for pre-match. But maybe that's to be expected, given the lack of caps and consistency in this Scotland side.
Portugal have been decent, but have made a lot of mistakes. A well-deserved try though.

The time the ball stays in the maul and it marches towards Scotland line...
Before Begic splinters round the corner and crashes over. Portugal get their reward with the final play of the half.
Samuel Marques to kick... and it's beauty from the touch line!
Scotland 33-0 Portugal
Peter Wright
Former Scotland prop on Sportsound
Scotland have got to work really hard defensively to close this half out.
Scotland 33-0 Portugal
Portugal go wide, but the pass isn't the best to find Lucas Martins. He controls with his feet and releases Simao Bento on the wing, and he seems to fly over the line!
But it's ruled out quickly for a foot in touch.
Portugal had another advantage anyway. Back to the corner.
Scotland 33-0 Portugal
Portugal win the ball back from the restart and have penalty advantage.. and it's kicked into the corner.
Can they end the half on a high?
