Wasps scored three tries as they claimed their third Premiership victory in six games this season to leave bottom club Bath still winless.

Veteran Jimmy Gopperth was stretchered off after a high shot from red-carded Mike Williams before tries from Gabriel Oghre and Tom Willis sent Wasps clear.

Bath were down to 13 men when Semesa Rokoduguni got a late consolation try.

But, despite the return of Bath number eight Josh Bayliss for the final four minutes, having been shown a yellow card for a deliberate knock on, the hosts could not get close enough to the Wasps line to claim a losing bonus point.

In a second half of three cards, Wasps were the first to lose a man when Jeff Toomaga-Allen was sent to the sin-bin - but it was just two minutes later when Williams was sent off for his stiff arm challenge on Gopperth. And, after a long delay, Wasps were left waiting anxiously for further reports on a suspected concussion issue.
