Bristol coach Richard Hill:
"I was a little worried when, for the opening 25 minutes, we seemed to lack composure.
"But our scrums did well from the start and we just about stopped their driving play and attacked on their fringes.
"The result means that our destiny in the Guinness Premiership is now in our hands and we are 11 points clear of the bottom side."
