Wasps ended their Franklin's Gardens hoodoo as a dazzling first-half performance secured a 24-11 win at Northampton Saints in the Premiership on Friday.
Saints had not lost to Wasps on their own patch since 2005, but first-half tries from Dan Robson, Rob Miller and Josh Bassett helped the visitors to a 24-3 half-time lead.
Northampton, who have struggled for consistency this season, improved defensively after the break and Sam Dickinson touched down late on.
It was too little too late, though, as Wasps jumped above Saints into fifth.
Jimmy Gopperth's early penalty put Wasps on the scoreboard before Miller and Bassett combined brilliantly to set Robson free under the posts for their first try.
The impressive Miller extended the lead further when he rode two challenges to squirm over the line and, after Stephen Myler put Saints on the board, Miller burst through the home defence before setting up Bassett for their third score on the half-hour mark.
Wasps defended valiantly against Northampton pressure towards the end of the half, but they lost Nick Hughes to the sin bin shortly after the restart for an accumulation of penalty offences.
Myler knocked the resulting penalty through the posts, but Wasps held firm despite being a man down.
Saints reduced the arrears further when a turnover deep in their own territory led to a charge down field and Dickinson reacted quickly to a loose ball to score a consolation try in the 72nd minute.
