It was by now ludicrously easy for the home side. Tries either side of half-time by Carreras and Ben Morgan extinguished any faint prospect that Bath could repeat what Northampton did to them last week and come to life as they were being buried.
Tries from Atkinson, skipper Lewis Ludlow, replacement scrum-half Ben Meehan and prop Jamal Ford-Robinson followed before Alemanno rounded off the rout.
