Pegasus were beaten 4-0 by holders UCD in Sunday's women's Irish Senior Cup final in Dublin, having defeated Belfast Harlequins 1-0 on Saturday.
It was a disappointing display by the Ulster side, who seldom threatened in front of goal.
UCD led 1-0 at half-time and added three further goals after the break to run out comfortable winners.
In the men's final a treble from Luke Madeley helped Three Rock Rovers defeat Dublin rivals Pembroke Wanderers 5-2.
In the women's decider, UCD broke the deadlock in the 13th minute when Lena Tice's free was converted by Emma Russell.
Abbie Russell made it 2-0 in the 42nd minute when she volleyed home a cross from Orla Patton.
Katie Mullan added a third when she sent a penalty corner low into the net past Pegasus goalkeeper Sammy-Jo Greer.
With two minutes remaining and Pegasus tiring, Sorcha Clarke wrapped up the win when she tapped in Deirdre Duke's cross.
