Owen Coyle is not a happy man. He makes three Queen's Park changes, hauling off his two centre-halves - Charlie Fox and Lee Kilday - as well as Aaron Healy.

Alex Bannon, Stephen Eze and on-loan Rangers wingers Josh McPake are on.

We spoke about Brain Graham before the show. He's Partick Thistle's main threat at corners and he's able to volley the ball waist high from a corner. There's no one anywhere near him.

The second goal is a great reverse pass, but Jack McMillan is in so much space. Queen's Park defensively have been so poor.

All I can see coming is more goals for Thistle.

It's going to take an incredible capitulation from Partick Thistle if Queen's Park are to even get to extra time.

Am I surprised? Not really. Partick Thistle are clinical and ruthless. Brian Graham has executed a game plan that he wanted. Thistle look bang at it and they have been from the get go.

Surely, that’s it now?

There’s such a flat, deflated feel in the stands from the Queen’s fans.

With a hint of frustration, too, because my goodness it’s another defensive error for the goal.

It's all square on aggregate with Scott Shepherd having put East Fife ahead at New Douglas Park.

All to play for in the second 45.

A first half Kris Doolan could barely have dreamt of. His side have absolutely blown Queen's Park away.

Brian Graham got the ball rolling with a majestic volley and Scott Tiffoney tapped in a second before Kevin Holt was first to react to a rebound in the box.

We've heard it asked before this season... is this tie done?

Very nearly a fourth for Thistle. Kyle Turner jinks away from a challenge on the right and crosses for the forehead of Brian Graham.

He powers a header at goal but Calum Ferrie is able to deny on this occasion.

A huge slice of fortune for Holt, but he's following in knowing it's coming back across the goalkeeper.

It looks like this game is running away from Queen's Park, if it hasn't already. They have to show something.

Ross Docherty whips a cross to the back post where Brian Graham is lurking.

His header is initially saved by Calum Ferrie, but it rebounds back off the shins of Holt and loops over the keeper.

Insurmountable? Maybe.

A silly booking for the goalscorer as he cynically trips Aaron Healy in midfield.

Scott Shepherd has East Fife back in their League 1 play-off semi-final with Clyde.

Really good play again down the right hand side. It's so, so well worked right from the start. The touch, the vision, the pass from Lawless.

Thistle are in real control now.

A brilliant goal that comes through the sourcery of Steven Lawless.

He cuts inside and slides a reverse ball to Jack McMillan, who squares for Tiffoney to slam home from a few yards out.

Thistle are in a very commanding position now.

Another sucker punch for the Spiders.

As was the case on Tuesday, they’ve played a lot of nice stuff in the early exchanges, but have just lacked that clinical edge.

Largely, that hasn’t been their problem, it’s been keeping them out at the other end which again, is the script tonight.

Ochilview is not the only ground for famous faces this evening. Over at New Douglas Park, former St Johnstone manager Callum Davidson and ex-Saints player Liam Craig are taking in Clyde's match with East Fife. It's 1-1 on aggregate.

What an incredible finish that is. Look at the intelligence. He doesn't lash at it, it's a side-foot finish with power.

It's tremendous. It's brilliant. Great composure.
