For the first time in what feels like an eternity, Glasgow have possession inside Harlequins' half.
Tom Jordan puts a kick in behind, which puts the pressure back on the home side.

Cadan Murley did all the hard work.
It is really tight, I thought there was enough on it.
Harlequins 0-7 Glasgow
A fairly clear knock-on cuts short the home celebrations.
Murley did well to race down the line and burst through a would-be tackler, but couldn't quite get it down.

Cadan Murley thinks he's scored in the corner for Quins, but the officials want to check the grounding...
Harlequins 0-7 Glasgow
The hosts are making good ground through their forward pack, and a lovely disguised pass from Marcus Smith takes Quins into Glasgow's 22 once more.
Harlequins 0-7 Glasgow
Jack Walker's throw is deemed to be not straight, so Glasgow will have a scrum and the chance to clear their lines.
It's disappointing for Quins, who will feel they should have taken points from that spell of pressure.

Glasgow have had two line-outs, will they get up and compete but risk getting pushed over?
Harlequins 0-7 Glasgow
George Hammond does well to gather the lineout throw from Jack Walker, and from the resulting maul, Quins win another penalty.
Marcus Smith goes to the corner again.
Harlequins 0-7 Glasgow
Quins have responded well to that early concession, and win a penalty which Marcus Smith kicks into the corner.
A big chance to hit back for the hosts.

Glasgow took advantage of Louis Lynagh's wing a few times to get easy advantage. Far too easy from Harlequins.
Scott Cummings
After 15 phases of relentless pressure, Glasgow power over the line.
The visitors' speed of ball never allowed Quins to get set in defence, and following an excellent step by Tom Jordan, Scott Cummings dots down from close range.
George Horne makes no mistake off the tee and Glasgow lead by seven.
Harlequins 0-0 Glasgow
Glasgow have started really well here, and make their way deep into the Harlequins 22.

You can't help but feel Harlequins have got the edge by being at home. They tend to play really well at home, they were outstanding last weekend.
Harlequins v Glasgow Warriors (20:00 BST)
Quins head coach Danny Wilson is well known to a number of Glasgow's current crop, having led the Warriors from 2020 to 2022, but isn't expecting that to play much of a part this evening.
"I think we both know each other really well," he said earlier this week. "I have worked with a number of these players but as much as I know about them, they know about me, so it probably levels itself out.
"Across the board, there is so much quality in that team. They have invested a huge amount of money in that squad and built a lot of depth.
"They are extremely dangerous and we will have to be right on top of our game to give ourselves an opportunity."
Harlequins v Glasgow Warriors (20:00 BST)
Glasgow Warriors head coach Franco Smith says he wouldn't have selected Sione Tuipulotu for this evening's game unless he was "ready to perform".
The Scotland centre picked up a knee injury against England in the Six Nations, and was expected to miss between two and three months of action, but returns after just five weeks.
"He slightly exceeded expectations," Smith said. "I was reluctant to involve him if he was not going to be the best version of himself.
“I wasn't forced to pick him. I didn't feel the need to pick him. I think the [other centres] are doing a great job.
"I can be honestly proud in the way that our [strength and conditioning] and our medical team go about their business. To have him ready to perform as well instead of just return to play is excellent."

Wonder who these chaps are supporting tonight...

Meanwhile, Glasgow have made five alterations to the XV that thrashed Scarlets in their last outing.
Scotland internationals Johnny Matthews, Matt Fagerson and Jack Dempsey all return to bolster the pack.
In the backs, Sione Tuipluotu's return from injury sees Tom Jordan switch to fly-half and Duncan Weir drop to the bench, while captain Kyle Steyn comes in on the wing in place of Sebastian Cancelliere.
Harlequins v Glasgow Warriors (20:00 BST)
Harlequins make two changes to the side that beat Bath in a high-scoring thriller last weekend.
Will Collier returns at tight-head prop and Irne Herbst starts in the second row.
England's Marcus Smith will guide the attack from fly-half alongside half-back partner Danny Care on Friday.
