With only a home game against Connacht and a trip to French minnows Montpellier left in the pool stages, Bath's unbeaten record looks in little danger.

Bath full-back Nick Abendanon was over the line in only the second minute of the Pool Four match.

Bath's Olly Barkley and Quins' Adrian Jarvis traded penalty goals, but Shaun Berne's try in the final minute of the "rst half gave the home side a daunting 17-3 lead at the break.

Jarvis pegged back three points early in the second spell, but an upset was never on the cards as Bath closed ranks. An injury-time try to winger Tom Williams and a penalty goal from former All Black Andrew Mehrtens gave Quins the final say and a losing bonus point.
