They face a more difficult challenge this Friday when they travel to France at the Stade du Hameau for the tournament's finale.
While Ireland are only two points behind, the French are unbeaten to date with an almost title deciding points difference of plus 137.
But aiming to deny their opponents the full house of victories this year, Ireland have brought back in Jenny Murphy, Larissa Muldoon and Ailis Egan to the starting line up in place of Grace Davitt, Amy Davis and Stacey-Lea Kennedy.
Egan will play at loose-head with Gillian Bourke swapping back into hooker with Doyle looking for his side to rise to the occasion.
He said: "The team put in a fine performance against Italy in their first ever game at the Aviva Stadium but we are under no illusions as to the challenge ahead of us.
"France are the form team of the Championship and beat England reasonably comfortably in Round 1. We will need to match their physicality and take our chances when they come."
