There was no debut victory for Bath new boy Rhys Webb as Bristol Bears continued their charged at a packed Rec. In-form Bristol Bears moved up to third in the Premiership with a 19-13 West Country derby win at Bath and Wasps ended London Irish's winning run on Sunday.
Bath and Bristol started the showdown at a packed Rec on the back of three consecutive victories, but it was Pat Lam's side who remained on a roll to move above Northampton Saints.
Chris Vui reached out to score the opening try just five minutes in and Callum Sheedy produced a moment of magic to set up a second Bristol five-pointer, picking out Alapati Leiua with a pinpoint cross-field kick after creating space with a clever show-and-go.
A second Rhys Priestland penalty just before half-time reduced the deficit to six points, but Harry Randall's try gave Bristol breathing space - Sheedy converting for a second time.
Priestland fed Will Chudley for Bath's only try 15 minutes from time soon after he replaced debutant Rhys Webb, but Bristol hung on to keep their rivals below them in fifth spot and complete a double after hammering them on the opening day.
Wasps are up to sixth after beating the Exiles 36-26 at the Madejski Stadium.
Irish had won three in a row, but Jacob Umaga was among five Wasps try-scorers in an entertaining victory on the road.
