Todd Blackadder’s men had lost their past three Premiership matches before the trip to Sixways to face lowly Worcester, but a second-half romp restored the winning feeling.
Ben Tapuai’s try and eight points from the boot of Rhys Priestland helped Bath to a 13-6 lead at the break.
James Phillips powered by four defenders to increase Bath’s lead and Fotuali’i charged down a Worcester clearance to score his second after Joe Taufete’e had responded for Worcester.
Perry Humphreys added a late try for Worcester, but they remain second from bottom while Bath are fifth.
Try stopping James Phillips ?
