Huge moments in the context of both sides' seasons and it is Kilmarnock who have, deservedly, gone two up.

They didn't settle on a one-goal margin and you could feel that second coming.

It's a big, big mountain for County now who have shown little sign of being able to tackle it.

You can hear the anger of the Hearts fans on the radio coverage, bleeding through. They're screaming at Neil Critchley, with the hosts on the back foot. Worrying times in Gorgie.

St Mirren claim a spot kick as Killian Phillips goes down under a Clinton Nsiala push.

The decision is a free-kick outside the box, but there's a VAR check.

Free-kick stands!

Corrie Nbada latches onto a smart flick from Fraser Murray, but blasts directly at goalkeeper Jordan Amissah.

A great chance for the hosts the double their lead.

Kevin Nisbet has the ball in the back of the net with a fine, first-time finish but there will be no Aberdeen goal on this occasion.

Jeppe Okkels had strayed offside as he ran into the wide position to provide the cross.

Yet another great chance squandered by St Mirren - and John Souttar is at fault again.

The centre-half dallies on the ball outside his penalty box, loses it and Killian Phillips' clever backheel puts fellow midfielder Roland Idowu clear on goal, but the substitute's low shot is blocked by goalkeeper Liam Kelly's legs.

Danny Armstrong, who is making his 150th appearance for Kilmarnock today, goes close with two efforts in quick succession.

His shot from a tight angle is turned behind and he then lashes one just over the bar from the short corner routine.

The hosts then keep the pressure on as Fraser Murray hits one just over. It's all Killie right now.

Rocky Bushiri is in pain after getting caught in amongst a couple of Aberdeen players as they all tried to meet a Hibernian fre-kick.

Bushiri is then back on his feet to head Jordan Obita's inches over the top.

He's got to do better from there - and he knows it as he retreats down the pitch muttering to himself.

Kenneth Vargas is coming on for Hearts, replacing Sander Kartum.

The Costa Rican hasn't been in the last few match day squads. A chance for him to resurrect his Tynecastle career.

A goalmouth stramash comes to nothing as Taylor Steven, Uche Ikpeazu and Josh McPake all have a swipe at the ball.

That's the closest St Johnstone have come to scoring since taking an early lead in the first half.

And here comes Dwight Gayle for Hibernian. He replaces Kieron Bowie.

Can the veteran forward make another vital contribution?

What a difference a goal makes. The Motherwell players are buzzing, they're creating chances at will and making all the right runs - and the home fans are loving it.

After half an hour and off the back of a run of four games with out a win, the same fans were perhaps questioning Michael Wimmer. Since then Motherwell have been excellent.

Aberdeen manager Jimmy Thelin has seen enough. He sends on Jeppe Okkels and Jamie McGrath and off come Shayden Morris and Pape Gueye.

McGrath will be playing in the green and white of today's opponents Hibernian next season.

That goal was all about the Belgian taking the initiative and making something happen.

Nico Raskin’s third goal of the season and the first one that’s not been a header.

Killie have made an impressive start to the second half.

A few corners in quick succession keep the pressure on County, with Fraser Murray's whipped delivery narrowly nodded wide by the stooping Liam Donnelly from close range.

A half-chance for Hearts as Frankie Kent gets on the end of James Penrice's corner. His header goes over the bar though.

Hibs have pinned Aberdeen back since the restart.

David Gray's half time talk looks to have done the trick with the visitors pulling the Dons all over the place at the moment.
