England delivered another flawless display in the defence of their Six Nations title, running in five tries to defeat Ireland in Limerick.
Day has been in good form and was first on the scoresheet again
Skipper Sue Day ran 30 metres to score the opening try before Georgia Stevens touched down for a 15-0 half-time lead.
The one-way traffic continued after the break with Amy Turner, Maggie Alphonsi and Danielle Waterman all going over.
Ireland did not get on the scoreboard and England are yet to concede a single point in this season's tournament.
"This was a good win, I'm delighted," England coach Geoff Richards said.
"We controlled the ball and dominated possession, as well as scrummaging well in difficult wet and windy conditions."
