Bristol Bears lost the battle of the two bottom sides of the Gallagher Premiership heading into the match to stay stuck at the foot of the standings.
In torrential conditions, London Irish comfortably won 23-7 at the Gtech Community Stadium against an undisciplined Bristol side thanks to tries from Benhard van Rensburg and Ben White and 13 points from the boot of fly-half Rory Jennings.
Bristol were the first to cross the try line through Harry Thacker, converted by AJ MacGinty, but that was a rare moment of cutting edge from a blunt attacking display.
