Decent set-piece opportunity as Stevie May flicks the ball round Alex Gogic and gets clipped.

It's about 20 yards out. May will take... He tries to go back across the keeper, but it bounces well wide. Harmless.

Superb defending from George Stanger, whose last-ditch tackle on Toyosi Olusanya prevents the striker getting a shot away when through.

Terrific from the centre-back.

St Mirren launch a free-kick into the box and Livi deal with it initially. Jonah Ayunga is able to take it down, though, and he shuffles left before unleashing a venomous strike at the near post.

Jerome Prior bats away. Decent chance.

What a bit of defending - from Mikael Mandron!

Livingston hit on the counter and the ball is threaded to Brooklyn Kabongolo, who takes a touch to nearly go clear through.

But Mandron is back there, sliding in to hook the ball away from the onrushing Livi defender.

Roles reversed there.

All Aberdeen's good work was almost undone by another one of their unwelcome traits this term - an inability to defend set-pieces.

The crossbar came to their rescue this time, but it won't be their saviour if they continue to make mistakes like that as this game continues.

It's good movement from Tshibola, he lost his man there.

This has been Aberdeen's Achilles heel, constantly giving away opportunities from set-pieces.

That could, and maybe should, have been all square.

So close to an equaliser.

Aaron Tshibola heads a free-kick on to the bar - what a chance.

Dimitar Mitov may have got a slight touch on it. Aberdeen's set-piece vulnerability coming to the fore there.

Aberdeen are appealing for a penalty.

The ball comes off Robbie Deas' arm as Kevin Nisbet took a touch, but it's tucked in and a pretty natural movement.

Bobby McLuckie has scored for East Kilbride at Dumbarton in League 2.

If they win and Spartans lose at home to Elgin City, then last season's Lowland League champions will make it back-to-back promotions.

Much better from Kilmarnock.

Winger Nicky Clescenco, on his first start, beats Alexander Jensen with ease down the left and drills a ball into the box.

It comes to nothing, but it was neat play.

Too warm for a pie? Never...

Arbroath and Partick Thistle are safely in the play-offs, although the Gayfield side will want to keep their noses in front of Dunfermline Athletic, who are also guaranteed a place in that scrap to meet the team that finishes second bottom in the Premiership.

While Aberdeen have started well, they are being helped by a Kilmarnock side who have made a mistake-laden start.

Certainly in these early stages you can sense a real nervousness from the visitors, particularly at the back.

Toyosi Olusanya keeps getting the ball in the box, but not in enough space to get a strike away.

Aberdeen are dominating proceedings at the moment. Kilmarnock have yet to start.

First real chance for St Mirren as Declan John scurries free on the counter.

Ryan McGowan does well to get back but John is able to get the shot off, only to fire into the side netting.

Goal number one on his sixth appearance in the red of Aberdeen for winter signing Afeez Aremu.

He and his team-mates have settled into this crunch match well.

It's already got worse for Kilmarnock.

Dom Thompson has had to replaced the injured Jamie Brandon.
