Reigning Premiership champions Exeter Chiefs scored seven tries for a bonus-point win as they rallied from last weekend's European exit to beat Wasps.
Wasps led 13-10 at the break, thanks to Josh Bassett's try, converted by Jacob Umaga, who also kicked two penalties.
But the Chiefs ran in five second-half tries to add to the first-half scores by Ollie Devoto and Jonny Hill.
Scotland's Stuart Hogg went in twice, followed over by Facundo Cordero, Wales prop Tomas Francis and Joe Simmonds.
Stand-off Simmonds also kicked four of his seven conversion attempts for an individual 13-point haul in an Exeter victory that ensures they stay second in the table.
Ninth-placed Wasps, who suffered a sixth defeat in their past seven Premiership games, could be overtaken by Newcastle if Falcons win later in the day at home to leaders Bristol.
Wasps were looking for a first Premiership double over Exeter, having beaten a significantly weakened Chiefs side 34-5 at the Ricoh Arena back on 2 January.
But the Coventry side have only ever won once before at Sandy Park, 26-19 in April 2019 and, once Exeter edged in front early in the second half, there was no way back for the visitors who simply made too many errors.
Chiefs' win also included a return from the bench for England wing Jack Nowell, who played the final 20 minutes, his first appearance in six months following ligament surgery and then a hamstring problem.
After Devoto's early try, Umaga got Wasps on the board with a penalty before hooker Luke Cowan-Dickie set up the Chiefs' second try for Hill to extend their lead.
Wasps responded with a second Umaga penalty and then a converted try following full-back Hogg's error.
Exeter's Scotland star had plenty of time to launch a clear kick into touch from inside his own 22, but Bassett charged it down and then gathered for a try.
But Exeter moved up a gear after the break and went back in front when Devoto created the space for Hogg to atone for his earlier mistake.
Cordero then intercepted Wasps centre Malakai Fekitoa's pass to score before Francis crossed for his first Exeter try, followed by two more late scores for Simmonds and Hogg.
