United are really pushing now.

Sam Cleall-Harding fires a shot towards goal from the edge of the box that's well saved by Ayr goalkeeper Liam Russell.

Moments later, Luca Stephenson puts a shot wide.

A bright start to the second half from Dundee United.

Half-time substitute Kristijan Trapanovski cuts inside off the left flank after a tidy move, but his shot towards the far corner is blocked.

Ashley Hay hits the bar after getting on the end of a corner.

It's just been one of those afternoons for Dundee.

There are more than 1,200 fans crammed into Carmuirs Park for this one.

That's almost six times the average attendance.

Dominic Thompson's excellent strike has Kilmarnock in pole position to progress but Dundee will be wondering how they're not at least level.

They should have scored before Thompson's opener and have controlled most of this first half.

The fine details are costing Steven Pressley's side and Kilmarnock will scrap to protect this advantage given the long winless run they've been on.

Dom Thompson's stunning volley remains the difference at the break.

Despite Dundee being the side in control for the majority of the first half, it's the home side who are in front.

A breathless first half, with both teams going for it.

The quality of the two goals cannot be understated. In particular, Killian Phillips' pass in the build-up to St Mirren's opener and Scott Arfield's dummy before his equaliser. Top class.

Where has this level of energy and belief been in the league?

A very forgettable half of football at Tannadice ends goalless.

It's been almost all Motherwell, but their killer touch has been missing.

The closest they've come was when Tawanda Maswanhise went clear through and fired past Trevor Carson, but Alex Iacovitti got back to block on the line.

One-way traffic, but no breakthrough.

Scenes no-one* likes to see at Tannadice as both sets of players pile into each other after Amar Fatah barged Leon King into advertising hoardings behind the goal.

Fatah and Marco Rus both go into the referee's book.

*everyone.
