IRELAND bounced back from their heartbreaking defeat to France with their sixth successive win over Scotland in Edinburgh on Saturday.
Centres Lynne Cantwell and Geraldine Rea ran riot, scoring three tries between them, while Niamh Briggs also crossed.
Richmond's Cantwell got Ireland up and running, shrugging off Charlotte Veale to cross for an unconverted try inside six minutes. She almost got a second, only to be barrelled into touch by Katy Green.
Scotland's Lauren Harris hit back with a try and the sides went in level at the break, but with Fiona Coghlan, Gillian Bourke and Joy Neville establishing Irish dominance up front, the girls in green were in control and soon went over for a second try.
Scotland's work at the breakdown had been frustrating Ireland, but Philip Doyle's charges finally found some momentum.
The forwards did the hard work, creating the space for Highfield's Rea to crash over in the corner and, although she then spent 10 minutes in the sinbin, Ireland rode out the storm.
Briggs made the lead comfortable before player of the match Cantwell finished the job with her second try.
