Tannadice loved that.
This place was already vibrating before Ayr were reduced to 10 men.
The expectation level just went up another notch. Glenn Middleton gets a huge response as he asks the crowd for more.
I don't know how much more they can give.

BBC Sport Scotland at Tannadice
Tannadice may be a tad frustrated, by every time the hosts have a sniff at goal, this place gets LOUD.
"United we love you" ringing around three of the four stands.

Now the home crowd are up.
Great play from Tony Watt, who feeds Glenn Middleton out wide. The winger's delivery is n0t great, but the home defence is all over the shop and it eventually goes behind for a corner.
Aidan Fitzpatrick
We have a goal in the Scottish Championship!
Aidan Fitzpatrick has given Partick Thistle a second-half advantage against Airdrieonians.

It's the visitors who have the first chance of the second period.
The ball sits up for Anton Dowds, who volleys into the ground. It's right at Jack Walton, though.
Second halves are under way now...
