Christian Wade produced a breathtaking performance as he scored seven times and made sure Wasps put down a marker on their way to this year’s Singha Premiership Rugby 7s final.
Wasps will now travel to Twickenham Stoop on August 28 after they won all three of their Group C games at the Ricoh Arena – Wade picking up Man of the Round for his efforts.
They will be joined at the Stoop by Quins who will have the chance to go for glory on home turf after finishing runners-up on the night.
Wasps started as they meant to go on, with Wade helping himself to a hat-trick in a 40-14 victory over Harlequins in the evening's first contest.
Wade picked up the first two tries for the hosts with Joe Marchant keeping Quins in touch, before the floodgates opened and Brendan Macken added a third for Wasps with Wade and Dan Robson making sure of all the points.
Northampton Saints however showed that they were going to be real challengers to Wasps as they battled back from a quick-starting Saracens to pick up a 31-12 win in the second match of the evening.
Sarries went ahead thanks to a blistering break from Tom Whiteley before Dom Morris doubled their advantage after three minutes.
However, Saints kicked into gear shortly after and Tom Emery's score in the fourth minute got them on the board, before Sam Olver produced a lovely dummy to break free and give his side the advantage at the break.
And a Rory Hutchinson double after the restart made sure of the points for Saints before Alex Rayment put the final nail in Sarries' coffin.
Sarries had the chance to bounce back straight away however with a quick turnaround against Harlequins.
Whiteley bagged his second of the night to set Sarries on their way and, despite a second-half fightback from Quins, they held on for a a 24-17 victory.
While Saints might have started strong they came unstuck against a dominant Wasps side that saw Wade add his fourth and fifth of the night in a stunning 49-5 victory.
The Saints had no answer to the pace of Wade and Macken also got in on the act with a double of his own – Will Allman the solitary scorer for Northampton.
It went from bad to worse for Saints in the penultimate match with Quins, as Marchant scored his fourth of the night to get things going before Robbie Nairn dotted down.
Tom Emery got Northampton on the board shortly after, but scores from Sam Aspland-Robinson and Callum Waters was enough to get Quins over the line in a 26-12 win.
But the night belonged to the hosts who finished the competition with a 33-10 triumph over Saracens with Wade receiving a standing ovation for his efforts.
