Wales Women 7-12 Ireland Women
Ireland kept their dreams of a second Six Nations Grand Slam alive with victory over a dogged Wales side in Cardiff.
Ireland had the better of a scrappy first half but it wasn't until just before the break that Lindsay Peat finished off a rolling maul to score the game's first try.
Nora Stapleton added the extras and Tom Tierney's team took a seven-point advantage into the interval.
Wales came out fighting in the second half and Peat was sent to the bin as the pressure mounted on Ireland.
Shona Powell-Hughes touched down after a dominant scrum and the sides were level after 43 minutes.
Ireland responded well and looked to have scored again just after the hour but Paula Fitzpatrick was judged to have been held up by the TMO.
From the next play though, Ireland pounced, Hannah Tyrrell brilliantly controlling a loose pass to score in the corner.
Stapleton's conversion attempt fell short but Ireland held out to set up a Grand Slam decider with England in Donnybrook next Friday (Live on RTÉ2 and RTÉ Radio 1).
"That was an extremely tough game," Player of the Match Stapleton told RTÉ Sport afterwards. "A really intense game but delighted to come through.
"We started slow in both halves, which is really frustrating but credit to Wales. They're a fantastic side and they really put it up to us.
"We had to work so hard to get our phases together and play a bit of territory as well.
"We had a lot of five-metre lineouts and mauls, we just need to be finishing those. But we did in the end and credit to the forwards for continuing to push on."
World champions England crushed Scotland 64-0 at the Twickenham Stoop and will be hungry to seal their first Six Nations title in five years - Ireland and France have shared the last four titles since England completed seven in a row in 2012.
Stapleton is under no illusions that it will be a tough task but is confident Ireland can win their second Slam and third title in five years in Dublin next week.
"Of course we can (stop them)," she said. "They're very strong, they're very skilful but so are this crowd of girls.
"It's just who can up it that bit more on the day and who wants it more.
"We'll have confidence going into it and no doubt we're going to have massive support in Donnybrook as well."
