Scotland international Jack Cuthbert helped himself to a hat-trick as Bath made it six out of six in Amlin Challenge Cup Pool 4 with a routine 53-8 victory over Bucharest Wolves at the Recreation Ground.
The home side became the first team to post a perfect record in the pool stage this season as they piled on the points to underline their qualification for the quarter-finals. They scored nine tries in all, with Cuthbert crossing twice in the opening half to give his side a 24-3 interval lead.
Bath are one of three English clubs through to the quarter-finals, joining Wasps and Gloucester, and will be the top-ranked team with 29 points. The five pool winners will be joined by three runners-up from the Heineken Cup in the last eight.
Gloucester also made it six from six as they ran in six tries in their 36-16 home win over Mont-de-Marsan.
England hopeful Billy Twelvetrees came off the bench to grab a second-half penalty and convert the final try by Jonny May.
May was one of two Gloucester players to cross twice, with Henry Trinder following suit, while Charlie Sharples contributed a try in the 22nd minute.
Worcester ran in 11 tries in a 71-19 win over Spanish champions Bizkaia Gernika.
