Mikael Mandron is picked out at the back post by a looping cross, and he does well to bring it down but can't get his shot off on the spin just six yards out.

Anytime the ball gets launched into the Dons' box, they look rather nervy and unsure how to deal with St Mirren's physicality.

That should be 2-0 Hearts!

Blair Spittal plays James Penrice down the left, he picks out James Wilson and the 17-year-old sees his goal-bound shot blocked behind.

He should be scoring there.

Early swap with St Mirren, 17-year-old Callum Penman is off. Elvis Bwomono comes on.

Penman was booked just moments before the change and needed the physio after going down.

Jordan White goes for the bottom right corner, but it's tame and not close enough to the post and Jordan Smith dives across to make the save!

Hibs will probably feel that is justice done, given how harsh it was on Nicky Cadden.

The ball is not going in the net, it's going to run out for a goal kick. I think it's really harsh.

And Ross County are awarded a penalty. It's harsh on Nicky Cadden because he has no time to react and James Brown, who missed the ball completely, is right in front of him.

His arm is out though and they're pretty much always given.

That's as close as either side have come. Noah Chilvers swings a lovely ball from the left-hand side and James Brown steams in at the back post, and misses it.

It's hit off Nicky Cadden's outstretched arm and Jordan Smith makes the save. Now the referee is being sent to the monitor...

It could be a penalty to County.

Derek McInnes far from happy with the movement of his strikers. Killie have had plenty of possession but lots of passes in the final third going astray.

After a much better period for St Johnstone, Max Kucheriavyi enters the book for hauling Tony Watt back as he attempted to start a counter.

The hosts growing into this more, though...

The pitch is soft and it's really cutting up. It's just a battle at the moment.

Aberdeen have responded well to falling behind.

They had a sustained period of attacking pressure with Jeppe Okkels having a half-chance easily saved by Zach Hemming.

The Dons had a penalty appeal dismissed after Alex Gogic clashed with Topi Keskinen and Richard Taylor fell on the ball in the box - neither the foul nor the supposed handball merited any intervention from the officials, it would seem.

Kilmarnock have fired a shot back, with Bobby Wales powering a header at goal from eight yards out but Craig Gordon saves with his knees.

It's been fairly even so far.

What a start from the home side and what stands out is the quality of the goals, both in build-up and execution.

The second was an excellent chest through from Stevie May straight into Scott Pittman's path and he squared perfectly for Cristian Montano.

Superb stuff from David Martindale's side.

With just one recognised centre-half in the St Johnstone backline, you can understand why Motherwell are pressing high - and fast.

Some nice slick play from the visitors on a not so pretty looking pitch.

A disastrous start for Aberdeen, and Slobodan Rubezic in particular.

A real moment of folly has handed the visitors the lead.

St Mirren have certainly started this one on the front foot, the Dons look like a bag of nerves at the back.

Ellery Balcombe, that's a cracking first save in a Motherwell shirt!

It's neat work from St Johnstone down the left and Victor Griffith had a nice little shot back across goal but the former St Mirren shotstopper got a big hand to claw it away.

Hibs send a long ball in behind the County defence, it bounces in the box and Dwight Gayle lashes the ball over the Jail End.

Not a great game so far. No wonder on this park.

Close to a second for Hearts.

The hosts are patient in their passing before working an opportunity on the left. Blair Spittal gets free and cuts back for James Wilson, who puts his effort just over the bar.

Worryingly for the hosts, Elton Kabangu is needing physio treatment now.
