Morton 0-4 Dundee United
Morton fans likely to feel aggrieved by that penalty decision not going their way just before that goal went in.
They're streaming out of Cappielow in their numbers.
Tony Watt
Right up the other end and into the back of the net.
Jack Baird gets robbed of the ball inside his own half trying to pass back to his keeper. Tony Watt storms forward under minimal pressure and coolly slots it home.

Mullen sends it long and Jai Quitongo picks it up.
He makes a great run forward and hits the deck just inside the United box under the challenge of Craig Sibbald - no penalty for the home side though.

Fotheringham's turn to have a go now. He lets one fly from inside the box but Jack Baird is there to turn it wide.
Glen Middleton delivers the free-kick that's glanced on by Kai Fotheringham at the near post but there's no one there to tap it home.
There's a wee bit of afters in the box and Ross Graham and Kirk Broadfoot are both shown a yellow card.

Just spotted Jim Goodwin on the touchline there and he doesn't look very happy for someone whose side have just gone 3-0 in front.
Louis Moult
Game over?
It's a great finish from Moult to slam his strike into the roof of the net from close range.
Hard to see a way back for Morton here...

Jack Baird heads into the side netting in the very early stages of this second half.

Back under way at Cappielow and a half-time change for the home side as Michael Garrity comes on for Iain Wilson.

They're getting really close now and they'll be desperate for that third goal to kill this game and get the tree points.
Every game now is a cup final. They'll be desperate to get it over the line and tonight could be a huge step towards that.

Ross Docherty’s had a stop-start season with injuries, but tonight you see what he can bring to the team, both in terms of that headed goal - his third of the season - but also in keeping control of possession in midfield. He’s such a tidy footballer.
That opener calmed the visitors down and Glenn Middleton’s second is one the winger really enjoyed celebrating with the coaching staff and subs, who were all thrilled for him.
Dundee United boss Jim Goodwin has tried to urge his side to play down Morton’s left, where Tyler French is a right-back playing as left-back.
The absence of George Oakley for Morton has cast a huge cloud over the hosts’ evening from the off.

Keep 'em closed!
United fans, fancy reliving that Glenn Middleton goal?
HT: Morton 0-2 Dundee United
Morton fans, avert your eyes.
Here's the moment Ross Docherty headed his side in front.
Well at half-time it looks like Dundee United are on course to go seven points clear at the top of the Championship table.
It was a dominant first half display from the visitors who bagged two goals for their efforts.
You know what they about 2-0 scorelines though, and we all know anything can happen in the Championship.

Jai Quitongo gets the first booking of the game for simulation.
He goes down rather dramatically after the briefest of nicks from Jack McClelland.
Morton 0-2 Dundee United
A wee bit of confusion between Ryan Mullen and his defender.
The corner comes in, the defender tries to get rid but Mullen dives in to try and gather - meanwhile Tony Watt is swivelling around on the ground trying to stick a foot on it.
Morton eventually get rid though.

That was close from Morton!
Totally against the run of play Robbie Muirhead finds himself with a bit of time on the ball right at the edge of the box and has a go, his effort goes wide though.

And here's the moment Middleton followed it up with a goal of his own.

Speaking of the captain, here's how he put his side in front.
Morton 0-2 Dundee United
I thought that was about to be another!
Glenn Middleton's cross finds Ross Docherty just inside the Morton box, he lays it off to Craig Sibbald who lashes a strike at the goal but he can't direct it on target.
Up the other end, Iain Wilson tries a shot from the edge of the box, it takes a deflection and goes out for the corner. The ball's eventually delivered back across goal and Ross Docherty has to stretch clear - looks like he's hurt himself in the process as well.
Morton 0-2 Dundee United
Well that was all a bit hectic, still 20 minutes of the first half to go!
Can't complain though, I did ask for goals...
