Swansea's Tyrone Maullin is stopped short

Bath's Mike Catt then fed a defence-splitting inside pass to Voyce, who sprinted 30 metres for his first try that full-back Matt Perry converted.

Arwel Thomas missed three kicks during a six-minute spell before eventually placing one between the posts.

But the sharp-shooting Perry hit back twice to put Bath 13-3 ahead at the interval.

Thomas reduced the deficit with a penalty, but back came the consistent Perry.

Voyce added his second when he ran clear on a three-man overlap, then completed his hat-trick from Catt's exquisite pass.

Ireland international Maggs then put the icing on the cake when he sprinted 50 metres for his try.
