Mitch Pinnock balloons the ball over the bar again after more excellent link play by Greg Kiltie. He's been electric tonight.
Kilmarnock in control. St Mirren have struggled for goals all season, and they don't look like scoring right now.
Kilmarnock 2-1 St Mirren
Kilmarnock are so close to a third!
A header in the box is flicked on by George Oakley, and Jake Doyle-Hayes has to nod it off the line for St Mirren.
The home side definitely look the stronger at the moment.

Quote MessageNot a penalty as Shaughnessy gets a touch on the ball. Kiltie wasn't complaining too much which usually gives it away
Kilmarnock 2-1 St Mirren
That is a huge call from referee Don Robertson.
Greg Kiltie nips in ahead of Joe Shaughnessy and the ball spins in his favour, he drives into the box, and the St Mirren captain slides in as the Kilmarnock forward hits the deck.
No penalty. Replays show that Shaughnessy got the ball. Great challenge. Great decision from the referee.
Kilmarnock 2-1 St Mirren
We're under way again. More goals? I reckon so.

Kilmarnock are proving that Kyle Lafferty has been the beneficiary of a much-improved team overall, rather than doing it all on his own.
George Oakley has put in a great shift so far.

Quote MessageIt's entertaining but there's so many mistakes out there. All of the goals were very avoidable but that makes it a great spectacle for us. This could end 4-3

Quote MessageThe timing of George Oakley's run was fantastic, I thought he might have gone himself but it's a great cutback. St Mirren got their line wrong trying to play offside
Greg Kiltie
What a turnaround!
George Oakley has done really well as a replacement for Kyle Lafferty. He gets onto the ball in the box, and cuts it back for Kiltie.
The Kilmarnock forward has plenty to do, but his composed finish goes through the legs of a defender and in off the post. Superb stuff.
The lack of pressure from St Mirren was bizarre, though.

Now St Mirren threaten as a header is flicked on at the near post, but nobody is waiting to tap home.
Just before that, the visitors were claiming for a penalty for a handball from Mitch Pinnock.
Replays suggest it did strike his arm, but it was by his side.
Kilmarnock 1-1 St Mirren
George Oakley is a lockdown haircut away from giving Kilmarnock the lead.
A brilliant curling cross comes in from the right again, this time from Ross Millen. The big striker flings himself at it, but just can't connect and the ball drifts behind for a goal kick.

Quote MessageThe delivery is fantastic but the intent from Rossi to get to the ball is first class.
Zeno Ibsen Rossi
We're all square!
This one is all about desire. Corner in. Centre-half chucks himself at it. Goal.
Superb from the Bournemouth loanee. Game on!

Quote MessageThat's a penalty all day long. Shaughnessy has both arms around Oakley.
Kilmarnock 0-1 St Mirren
Kilmarnock are screaming for a penalty here! Chris Burke whips in a superb ball, and George Oakley tumbles to the ground under severe pressure of Joe Shaughnessy.
The St Mirren captain certainly had his hands on Oakley.
Kilmarnock 0-1 St Mirren
That is excellent defending from St Mirren's Richard Tait. He sprints back to cut out a cross that was about to find the gleeful Mitch Pinnock, who would have surely have levelled.

Quote MessageTommy Wright won't be happy here. His goalkeeper has already thrown one in and now Broadfoot nearly handed St Mirren another goal. Durmus should do better to stay onside
