Worcester's hopes of progression in the LV= Cup suffered a major setback as they were well beaten at Bath in their second pool match.
The West country side crossed the Worcester line seven times with Josh Drauniniu scoring Warriors' only try in the second half.
Tom Heathcote landed an early penalty for Bath but Joe Carlisle then kicked two for Worcester, who briefly led 6-3.
That was as good as it got for the visitors as Bath crossed three times to open up a 22-6 interval lead.
Bath profited from spilt Worcester ball as Heathcote ran in their first try on 20 minutes while debutant Francois Louw was on hand five minutes later to score their second.
Matt Banahan then got in on the act as he crossed for the third try nine minutes before the interval.
Heathcote kicked two of the three conversions as Bath effectively took the game away from the Warriors before the interval.
Bath did not ease up in the second half as full-back Jack Cuthbert rounded off a fine backs move for the fourth try with Heathcote again adding the extra points.
Worcester rallied and scored a neat set-piece try when Josh Drauniniu took a sharp pass from Carlisle to cross for what proved to be their consolation effort and Carlisle added the conversion.
But Bath were not finished and when Sam Betty was yellow-carded for a dangerous tackle they made the numerical advantage count.
Ben Skirving, Olly Woodburn and Nick Abendanon all crossed as Bath stretched away while Heathcote finished with four conversions and a penalty to go with his try.
VIEW FROM THE DRESSING ROOM
Worcester forwards coach Phil Davies told BBC Hereford and Worcester:
"In the first half we made four errors and they scored tries from three of them.
"We only gave away four penalties so it was quite a constructive first half other than those errors that were very costly.
"They scored two good tries but you would expect that from a team of their quality.
"We kept the ball well [in the second half] and had good territory, but we just couldn't convert that possession into chances to score."
