Dean Cornelius
A cool, calm and collected finish from Dean Cornelius.
St Mirren defence is stretched as a Motherwell pass sends the ball towards the corner flag and it is immediately turned back across the box by Joseph Efford.
Cornelius take a touch to settle himself and shapes to send it back across the goal before showing poise to pass it in the bottom corner.

Hibernian debutant Harry Clarke is playing as a rampaging centre-back, getting forward all the time, and he drives a shot in from distance which Benjamin Siegrist has to tip over the crossbar.
Calvin Ramsay
It has been coming as Aberdeen surge ahead.
Calvin Ramsay cuts in from the right flank and hammers a left-drive inside the far post for a thumping opener.

Former Hibs player Scott Brown is taking in the match at Easter Road.
How the home side could with the kind of drive he provided from midfield in his pomp.
Hibs have had most of the ball but are doing very little with it.

Ilmari Niskanen gets a touch at the back post but it finds the side netting.
Barrie McKay

Liam Boyce's goal-bound strike is blocked brilliantly but the rebound falls to McKay, whose deflected effort beats Ross Laidlaw.
Crackin' game in Dingwall.

Just as the game appeared to have settled down a touch, it bursts into life again.
A dangerous St Mirren corner is whipped in and once again a Motherwell defensive header ping-pongs off a teammate and falls advantageously for Conor McCarthy to slide in and turn it home.
Motherwell keeper Liam Kelly was furious with the referee as he thought he was impeded as he went to collect the corner.

St Johnstone's Tony Gallacher is carried off 10 minutes before half-time, with Callum Booth replacing him.
And, with his first touch of the ball, he tees up Ali Crawford whose shot is tipped past the post.
Ross County 1-0 Hearts
Almost a second for the Staggies as Regan Charles-Cook cushions a shot against the post after a lightning breakaway.
Again, Blair Spittal is the architect with a gorgeous ball off the right.
Alex Iacovitti
County have been ramping up the pressure and get the goal their recent dominance deserves.
Blair Spittal's free-kick from the right is bang on the money and Alex Iacovitti pokes in from close range.

Christie Elliott tees up Dundee midfielder Paul McGowan 20 yards out, but his curling strike is always heading over.
The hosts have yet to trouble Dons keeper Joe Lewis.
Motherwell 2-1 St Mirren
Eamonn Brophy receives the ball after a delicate flick from Jordan Jones just outside the box.
The striker spins around Rickie Lamie with ease to set himself up one-on-one but his angled drive smacks off of the post.
Ross County 0-0 Hearts
Wow. How's that not gone in?
A County corner is glanced on by a head at the front post and clips the inside of the back post.
The rebound falls to Harry Paton, who looks certain to smash in, but Liam Boyce is there with a goal-saving block.
Ross County 0-0 Hearts
A good, free-flowing move forward from Hearts results in Aaron McEneff attempting to catch Ross Laidlaw out at his near post.
The County keeper is wise to it, though, and gets down well to save.
Connor Shields
What a turnaround at Fir Park!
St Mirren's Joe Shaughnessy lets the ball run through his body in his own half, allowing Kevin Van Veen to latch onto it and play a quick through ball.
Connor Shields bursts onto the pass through a huge gap in the visiting defence and lifts a lovely finish over the keeper.

Ross County 0-0 Hearts
Oh, that's a sore one.
Jordan White's arm catches Stephen Kinglsey and the Hearts man looks to have a bit of his front tooth missing.
Sean Goss
A Motherwell throw-in sails towards the corner flag and is sent into the box by Connor Shields.
It zips across the surface perfectly for the arriving Sean Goss to strike first-time from the edge of the area. St Mirren goalkeeper Dean Lyness could have perhaps done more to save the shot at his near post.
Image source, BBC SportDundee 0-0 Aberdeen
Two good openings for Dundee and both fall to Danny Mullen.
Christie Elliott gallops down the right and his cross isn't dealt with by the Dons defence, allowing Mullen to get a shot away but it's easy take for Joe Lewis.
The striker then cracks an angled drive narrowly over in an entertaining start from both sides.
