Wasps held off a Leicester Tigers fightback to claim a first win at Welford Road since 2008 on Saturday, while Bath trounced Newcastle Falcons to continue their fine start to the new Premiership season.
Dai Young's side ground out a 34-22 success over the Tigers while the margin was much more convincing for Bath, who ran in eight tries in their 58-5 rout of the Falcons.
Leicester were left with a mountain to climb when, following a first half that featured one try for each side, Guy Thompson and Sam Jones went over in quick succession after the interval, with Jimmy Gopperth converting both scores to put Wasps 27-8 to the good.
A wonderful Ed Slater try and three penalties from Freddie Burns, who had split the posts once before the interval, got the Tigers back within five points and set up a dramatic finale.
Yet Wasps held on and secured a bonus point with a fourth try in the last minute, after refusing a kick at goal following two wasted penalties from Gopperth. The number 12 atoned for those misses by going over from a driving maul with two Leicester players - Ellis Genge and Peter Betham - in the sin bin.
Newcastle were outclassed at The Rec as Bath followed up their opening-round win over Northampton Saints with a thumping victory in Todd Blackadder's first home game.
Semesa Rokoduguni and Dave Attwood each crossed twice for Bath, who also scored through a penalty try, Kane Palma-Newport, Matt Banahan and Elliott Stooke.
The Falcons' only points came through Ally Hogg with four minutes remaining.
