Stand-out forward Aoife Wafer crossed for two tries as Ireland ran out convincing 40-14 winners over Wales in the women's Six Nations Championships in Newport on Sunday.
Along with No 8 Wafer, teammates Linda Djougang and Dorothy Wall also each crossed for two tries.
Wales had taken an early lead through Carys Cox but were on the back foot for most of the game against a dominant Ireland side.
Wales replacement Hannah Bluck scored a second try for the home team in the second half, but it was not enough to keep the Welsh from heading for a wooden spoon after a fourth defeat from four matches.
England set up a Grand Slam decider against France at Twickenham next weekend with a 59-7 rout of Scotland on Saturday.
France were far less impressive as they were forced to come from 21-12 behind at half-time to beat Italy 34-21 for their fourth win of the championship.
England are big favourites to secure a seventh consecutive Women's Six Nations title after extending their winning run to 24 matches with a nine-try display at Leicester's Welford Road.
