Thistle have a chance of their own from a corner up the other end.

This time Darren Brownlie rises but he just can't get his header on target.

Thistle are having to deal with a bit of County pressure here as the hosts win another corner.

It's another Yan Dhanda cross, but Keith Watson glances well over from the front post. Half a chance.

David Mitchell was in no-man's land... I have no idea what he was doing.

He had an eternity to track and take it and he was nowhere near it.

That's two chances now he's been found wanting when the ball has come into the box.

Another County corner. This is better from the home side.

The delivery is good from Yan Dhana, but credit to David Mitchell this time. He gets a cracking punch on the ball.

David Mitchell is all over the shop again.

He comes out to collect a ball from orbit, but he gets nowhere near it and Ben Purrington meets it with his head.

The Thistle defence manage to clear the effort off the line.

It's just all breaking down for County.

Yan Dhanda takes a burst to the bye-line but Aidan Fitzpatrick is too strong and wins a goal kick.

Brian Graham with the ultimate 'let them know you're there, son'.

Jack Baldwin is ushering the ball out of play and the Thistle striker absolutely bodies the County defender about five yards off the pitch.

Vital defending from Jack Baldwin.

Darren Brownlie meets a deep free-kick at the back post. Scott Tiffoney looks set to tap in but Baldwin clears behind.

Thistle make a mess of the short corner.

Nice feet in midfield from Victor Loturi - one of the finest names in Scottish football - but he's eventually swarmed by Thistle.

Thistle will be quite content with this little lull in play.

They've had to deal with a lot of high balls, but it's been relatively comfortable so far after a frantic start.

Every minute will feel like an hour for that backline, though.

Again County ask questions. They're playing so direct.

The ball ends up ricocheting then just hits Jordan White and rolls behind the goal. Tough one to control.

County corner. They're pushing but yet to really test David Mitchell.

Yan Dhanda's outswinger doesn't get the chance to create any danger as the whistle is blown for a foul.

Malky Mackay will be feeling quite positive about the way the game has opened up, but Thistle have shown enough of late that they know they can hurt their opposition.

The big thing is, they have to be aware to not gift anything to County, because that could just be what's needed to ignite a comeback.

Jordan White, still sporting a big band of white strapping round his head, can't make clean contact with a cross into the area.

County still enjoying most of the ball.

Partick Thistle have reacted well after the initial early pressure from Ross County. They've retained possession which allows them to calm down and work their way into the game.

Football cliche time. If Thistle get the first goal, you'd think the tie is over.

But if County get it... aye, we'd be in for a game. Both sides are going for it so far.

Corner comes to hee-haw.

Breathless start to this second leg, though.

Thistle fly up the other end and win a corner.

Lovely start. More of this. Cheers.

Nervy moment inside the first minute for Thistle keeper David Mitchell as County pepper the away goal immediately.

Keith Watson is denied on the half volley with a big block.
