Rob Dewey went over for Glasgow's try

Glasgow made the brighter start and fly half Ruaridh Jackson had already hooked a penalty wide when Glasgow went over after four minutes.

Wasps full back Mark Van Gisbergen failed to deal with an innocuous box kick and the Glasgow back row jumped on the mistake with John Barclay and Richie Vernon linking well send winger Rob Dewey over in the corner.

Jackson slotted the conversion to make it 7-0, and only a post saved Wasps from slipping further behind when Jackson had another long range pot at goal after ten minutes.

Clearly riled, Wasps' frustration boiled over when Payne aimed a right hook at Graeme Morrison while the Glasgow man was being held by a team-mate of the prop. He escaped punishment though and the flashpoint actually served to kick-start Wasps.

Within a minute they had won a penalty of their own, Cipriani kicked for touch and Wasps had a five metre line-out.

Their set-piece held up, with Richard Birkett taking Rob Webber's throw, but their pack could not barge their way over and moments later Payne was at the centre of the action again as he and Moray Low squared up.

Both men were sent to the cooler and for a while the game settled down.

Wasps got bacj in the game when Waldouck sliced through the heart of the Glasgow midfield to send Varndell in for the try.

Walder failed with a difficult touchline conversion and moments later Glasgow established breathing space again with another Jackson penalty to give them a 10-5 lead at the break.

In the second period Wasps spent ten minutes inside the Glasgow half they never threatened a second try while Glasgow, when they did come forward, came forward with menace.

Two excellent chances for tries were swarmed over by a desperate Wasps defence.

A Dan Parks penalty stretched the score to 13-5 after an hour, but Wasps had a final sting in them and after Walder's penalty had brought them within a score of the lead Varndell obliged with nine minutes left when he took Walder's short pass and stretched for the line.

Walder converted to make it 15-13.

Instead, Warriors steamed back at them in the final minutes and a devastating counter-attack cut Wasps to shreds.

Heroic defence from Wasps looked like saving them but Glasgow would not be denied. With two minutes to go a cross-kick from Dan Parks looked like putting in Pat MacArthur for a try but the hooker couldn't gather the ball. However, Wasps has been caught offside and Parks cooly slotted the penalty to give Glasgow the win.

After the game, Warriors head coach Sean Lineen said: “We saw some really good performances from the players that started tonight.

“We’ve worked hard on our contact and worked hard on our defence. We know clearly why Wasps scored those two tries and those things can be fixed.

“Our defence for long periods of the game was outstanding. I thought the scrum performed well and young Jon Welsh was brilliant. That’s what we want, real competition.

“I thought Peter Murchie did well. He was only meant to play for 60 minutes but he wanted to stay on for the whole game so that shows the ambition of these guys.

“The players worked really hard and that was a good workout for us. There are some sore bodies out there. That was a tough game before Munster.”
