Cardiff Blues, Montpellier, Castres and La Rochelle were the big winners on Friday in Round 6 of the Challenge Cup.
Cardiff Blues 74-6 Calvisano
Tom James scored a hat-trick for Cardiff Blues only a few days after his Wales recall as the Welsh region thrashed Calvisano 74-6.
Cory Allen also bagged a brace of scores in the nine-try rout at Arms Park.
Blues as a result moved up to 17 points in Pool 3, although Montpellier's convincing win over Harlequins rules them out of a runners-up spot.
Gareth Anscombe, in only his second game back from injury, kicked seven conversions after starting at fly-half.
Calvisano's sole points came from two penalties by Romania international Florin Vlaicu.
