It's been a day of penalties and penalty incidents in the Scottish Premiership. This one by Kevin van Veen wasn't convincing but it counted.

That man Malik Tillman impresses again, teeing up James Tavernier for an effort superbly saved by United keeper Mark Birighitti, who throws up a hand to palm the ball away.

He then gets down smartly to turn an Alfredo Morelos dig round the post.

St Mirren are managing this well. They replaced Mark O'Hara at half-time, presumably as he was on a yellow card and have been comfrtable for the most part.

Livingston have changed approach and come close on a couple of occasions but the damage was done in that first half. There seems little threat to the overall outcome.

United almost pull one back.

Aziz Behich's effort is definitely a cross, but loops over Allan McGregor's head and flies inches past the top corner.

At the other end, James Tavernier has a shot deflected narrowly wide as Rangers chase a third.

David Martindale is usually fairly animated on the touchline, but he's been more incensed with his team's performance so far than anything else.

Stephen Robinson on the other hand will be seriously impressed with his side's control in this half, despite Livingston having more of the ball.

Almost an instant impact from the Hearts subs. Stephen Humprhys skins Luke Chambers and gets into the box. He cuts it low, Josh Ginnelly misses the backheel. It comes to Lawrence Shankland on the turn but there's not enough venom to get past Sam Walker.

Kilmarnock then whip a free-kick in and Joe Wright bundles it into the side netting at the back post. They almost killed this game.

Lewis Stevenson, Josh Campbell, and CJ Egan-Riley go off for Hibs.

On come Marijan Cabraja, Joe Newell, and Mykola Kukharevych as Lee Johnson chucks the kitchen sick at this.

Aberdeen have a clear sight at goal as Ross McCrorie finds himself inside the penalty box.

But, after the big defender does well to control Jonny Hayes' chip, he blasts his shot well over.

Stephen Humphrys and Alex Cochrane are on as Robbie Neilson throws the dice in search of a Hearts equaliser.

Alan Forrest and Stephen Kingsley are off. Maybe harsh on Forrest, arguably Hearts' best player today.

David Watson, 18, has easily held his own against experienced campaigners like Hearts' Robert Snodgrass. Killie have to play at least half an hour with just 10 men.

Rangers two up and looking really comfy against Dundee United. They're passing the ball about really well, with some neat play - James Tavernier, Todd Cantwell and Malik Tillman all impressing.

They're queuing up to add to the scoreline - that might be a frustration for the Rangers manager, not putting chances created away.

Lawrence Shankland has his head in his hands - how has he not scored?!

The ball drops to the striker in the area, he lashes at goal and the ball ricochets around and eventually settles in Sam Walker's grateful grasp.

It's all Aberdeen at McDiarmid Park.

But, while only one goal separates the sides, 10-man St Johnstone are still in this game and are occasionally threatening on the break.

Livingston have had 62% of possession since the interval but haven't done enough, if anything, with it.

They're showing glimpses of some attacking impetus but they have the proverbial mountain to climb to get anything out of this game still.

Derek McInnes is making a change, in an attempt to keep this lead.

Jordan Jones is the man replaced by defender Luke Chambers. It's been another vintage Jones performance.
