We should have added that there were no fewer than three St Mirren changes at the break.

Conor McMenamin, Dan Nlundulu and Keanu Baccus are on, replacing Richard King, Roland Idowu and Mikael Mandron.

An update on that St Mirren non-penalty for you...

"In the opinion of the referee and VAR team, not a punishable handball as it was very close proximity and not unnatural."

How on earth have Kilmarnock not scored there?

Marcus Dackers reacts quickest to a long ball, but Shamal George saves his snapshot.

The ball loops into the sky and David Watson then tries to volley home, but it's blocked. Dackers gets to the rebound only to drag it wide.

Three good chances, all gone.

Just a few seconds into the second half and St Mirren captain Alex Gogic goes into the book for tripping Bruce Anderson.

The wind is now behind Killie. It didn't help the visitors.

We're up and running again...

I can see Craig Sibbald and Amar Fatah coming on for Dundee United.

Livingston thoroughly deserve their lead. They've been by far the better side over the opening 45 minutes.

They've been full of energy, hard working all over the pitch and have really limited Dundee United's time on the ball. As good as Livi have been though, United have been pretty poor. The home crowd far from happy as that half time whistle sounded.

Kilmarnock have scored seven first-half goals in seven games. Only Dundee United and Hibernian (six games) can match that tally.

The centre-halves have been really poor, they're all over the place. It's been dreadful from Dundee United.

Livingston have created some really good chances and have been excellent.

A contentious end to a first half in which Kilmarnock have caught St Mirren cold twice.

David Watson's goal came from nowhere, before Marcus Dackers' header further punished a St Mirren side seemingly still in shock.

To add to Stephen Robinson's woes, what looked to be a clear handball did not yield a penalty.

We'll hopefully get someone to clear that one up shortly.

Livingston have the lead through Scott Pittman and deservedly so.

The visitors were in charge for most of that first half and can count themselves unfortunate not to be further ahead.

Vicko Sevelj had United's best chance and really should've scored. Jim Goodwin's side have it all to do in the second half.

That should be 1-1. A Dundee United corner taken by Zac Sapsford is allowed to bounce in the Livingston six-yard box and Vicko Sevelj heads wide. He has to at least hit the target there.

There's penalties been given for less this season. We want consistency. Based on what we've seen before, I'm surprised it's not been given.

There's a shout for a St Mirren penalty as a corner is floated to the back post where Richard King nods the ball down. It looks like it strikes Robbie Deas on the arm and the VAR team are checking it out.

No penalty!

Can Ayr United boss Scott Brown put a spanner in the works for high-flying leaders St Johnstone?

No goals in Perth yet.

Partick Thistle are the only scorers so far in the second tier.
