Ireland 18 Scotland 14
It took a length-of-the-field interception from Beibhinn Parsons to give Ireland victory against Scotland in the Women's Six Nations at Energia Park.
The Irish delivered on their promise to move the ball, and forced a penalty for Ellen Murphy to make it 3-0 in the fifth minute.
They were soon in command and used the width of the pitch for Cliodhna Moloney to speed to the right corner.
They wasted no time in adding a second from Sene Naoupu in the 15th minute before the pace dipped and Scotland were able to use their set-piece scrum and maul to come into the game.
Scotland earned the tonic of a try by centre Lisa Thomson, converted by Helen Nelson for 13-7 on half-time.
Gradually, the visitors took hold of the territory, forcing Ireland into defensive mode for most of the third quarter.
It took the opportunism and athleticism of Parsons (right) to break that stranglehold, going the length for a try against the run in the 67th minute.
The Scots were down but not out as Emma Wassell burst over and Law converted to leave four in it with four minutes left to play, but Ireland just about held on.
Meanwhile, Wales let slip a half-time lead against Italy to begin with a 19-15 home loss.
Robyn Wilkins kicked an early penalty and also converted Hannah Jones' try to give Wales a 10-5 lead at the interval, with Italy scoring through hooker Melissa Bettoni.
After the interval, Sara Barattin was stopped just short of the line after a break, but the ball was quickly recycled for winger Maria Magatti to dive over.
Five minutes later, Italy worked the ball wide from a five-metre scrum and left wing Sofia Stefan was given a simple finish, with Michela Sillari converting both scores to make it 19-10.
Kelsey Jones scored from a Wales line-out, but Italy held on.
