Thanks to a steady scrum and a dominant line-out in which Ian Nagle and Dave Foley were on top for most of the contest Munster were provided with an excellent plaform with James Coughlan another who left nothing behind him on the night.
That pack was well marshalled by impressive scrum-half Conor Murray as coach Anthony Foley highlighted afterwards. "I thought our pack were excellent, the scrum steady and jumpers and lifters working very well and they were well controlled by Conor at scrum-half. All in all we'd have to be well pleased with that performance.
"That's a good Bristol side. There were a few ropey times particularly in the first half but the defence was superb, totally committed. Nine points from two outings ? If you'd offered us that at the start of this competition we'd have taken it."
Munster led 8-3 at half-time thanks to Declan Cusack penalty and try from prop Dave Kilcoyne. They added to that total three minutes after the restart when Danny Barnes scored wide on the right after a good line-out take by Dave Foley. Then in the closing stages O'Mahony ensured victory when he gathered Burke's perfectly placed cross field kick.
