Quote MessageDundee United are edging it in terms of possession but it's ebbing and flowing, end to end. It's a good game, brilliant to watch.

Livingston 1-0 Ross County
Livingston are dominating without being dominant, if that makes sense. They are doing all the pressing and winning the set-pieces but only one shot and one goal to show for it so far.
Ross County really struggling to retain possession in attacking areas, typified by Alex Samuel running in behind the defence and getting to the ball ahead of Max Strjek but being unable to find a team-mate.

Shane Sutherland
First blood to Caley Thistle in the Championship's only game today.
Ayr United 0-2 St Mirren
A superb bit of skill from Kyle McAllister and the midfielder who opened the scoring for the Buddies sets up Kristian Dennis in front of goal, but the striker somehow misses the target. A sitter!
Kelty Hearts 0-0 St Johnstone
The longer the minutes tick by without a St Johnstone goal, the sweatier the palms will get in the away support.
This one had the feeling of a potential banana skin and Kelty are holding their own so far.
Kilmarnock 1-1 Dundee United
It's a very even game at Rugby Park, though Kilmarnock are beginning to edge it and have offered a threat twice inside the box, with Fraser Murray and Rory McKenzie both getting into good positions but Benjamin Siegrist is able to save both comfortably.
Then Oli Shaw breaks through only to skew his shot wide of the post.
Aberdeen 1-0 Edinburgh
Funso Ojo connects sweetly with the bouncing ball but it cracks the outside of the post.
Aberdeen in total control, but still just the one goal in front.
Motherwell 0-0 Morton
For all their possession and chances, Motherwell are yet to make the breakthrough at home. Jordan Roberts is cutting a frustrated figure in the penalty box as crosses and cutbacks continue to evade him.
Partick Thistle 1-0 Airdrieonians
So close to a second for the Jags as Scott Tiffoney finds the frame of the goal with a fierce strike.
Jack Hamilton
The Championship leaders strike first as Jack Hamilton gathers a pass from Craig Wighton, shimmies past a defender, then cracks a shot in.

Brian Graham

Connor Shields dinks are cross in from the touchline and it escapes everyone in the middle before falling to Jordan Roberts at the edge of the box.
His shot is venomous but narrowly misses the target.
Dumbarton 0-0 Dundee
Dundee have had all the ball so far, but are yet to really test Sam Ramsbottom in the Dumbarton goal.
Cammy Kerr swings in a testing cross, but there's no-one on the end of it.
Ryan Hedges
It's been coming for Aberdeen.
Funso Ojo forces a save from Brian Schwake, the ball falls to Jonny Hayes who crosses for Ryan Hedges to stroke home from close range.
Image source, BBC SportRory McKenzie
Kilmarnock are level. Rory McKenzie finds a gap between two defenders on the edge of the box. His first shot is saved but the rebound falls back to him and he's able to slip it inside the near post.

A lovely free-kick gives the League 2 side an early lead at Holm Park.

Motherwell are knocking on the door now.
The ball falls to Barry Maguire on the edge of the box after a set-piece but his powerful drive is once again stopped well by Jack Hamilton.
