Wasps chalked up a fourth successive Aviva Premiership victory in spectacular style as they thumped leaders Saracens 64-23 at Allianz Park.
The hosts came into the game having lost just once in the Premiership all season, but never recovered from conceding three tries in the opening eight minutes.
Charles Piutau got the ball rolling for the visitors in the third minute, before flanker Thomas Young and scrum-half Dan Robson also crossed in quick succession to make it 19-0.
Saracens finally roused themselves and replied through a Charlie Hodgson penalty and a Brad Barritt try, but could not prevent number eight Nathan Hughes from finding the line twice in the space of four minutes to reassert Wasps' dominance.
Having led 31-16 at the break, the Coventry-based side soon stretched their advantage as Jimmy Gopperth capitalised on some poor tackling to go over for try number six.
And any chance of an unlikely Saracens comeback disappeared when skipper Alistair Hargreaves was yellow-carded for coming in at the side of a ruck on 47 minutes.
Piutau duly grabbed his second and Wasps' seventh try during Hargreaves' absence and although Jim Hamilton did manage a close-range reply for the league leaders, Robson touched down again late on to round off a magnificent day for Dai Young's men.
The result moves Wasps up from eighth in the table to fourth, while Saracens remains four points clear of second-placed Exeter, who were beaten by Sale on Saturday.
