A third wicket stand of 108 in 50 balls between Irish internationals Leah Paul and Rebecca Stokell was the catalyst for Merrion's 126-run win at Balbriggan. Paul hit 11 fours in a whirlwind 62 from 31 balls, while Stokell was no slouch either on her way to 41 off 31 deliveries (4 fours). Aisling Lawlor (25*) and Ally Boucher (22*) then added an unbroken 53 in five overs to take Merrion to a total of 210 for 4. The chase never got going as Ella Marsh's 25 was the best of Balbriggan's 84 all out. The wickets were shared with two apiece for Aoife Brennan, Victoria Hayes, Leah Paul, Ashwi Manoj and Bella Armstrong.

A second wicket stand of 86 in 9 overs between Irish internationals Louise Little and Orla Prendergast propelled Pembroke to a 49-run win over Malahide in the other semi-final. Little top-scored with a 43-ball 69 (8 fours, 2 sixes), while Prendergast also cleared the ropes twice on her way to a 35-ball 52. Pembroke lost early wickets and never really threatened the total at any time - ending on 123 for 6, with Arlene Kelly and Anna Kerrison each making 25.

Pembroke as expected proved too strong for Rush at Sydney Parade. Pembroke racked up 185 for 5 with Louise Little top-scoring with 64, and runs too for Orla Prendergast (39) and Sarah Forbes (37) - two wickets for Ocean Bartlett. Hannah Little then made it a good day for the family by taking five wickets for 13 - unlucky for Rush who were bundled out for 63.

Closest game of the night was at The Village where Malahide edged out Clontarf by 15 runs. Meg Thompson made 22 and Anna Kerrison an unbeaten 31in a home side total of 132 for seven - two wickets apiece for Lucy Barry and Anna Pasley. Clontarf were in early trouble, but recovered thanks to Gemma Sargent and Hannah Pasley's 7th wickets stand that ultimately fell just short.

New Zealand professional Bella Armstrong continued her rich vein of form as she followed up Sunday's century with 71 in a Merrion total of 169 for 4 at Rathmines - runs too for Irish internationals Rebecca Stokell (35) and Leah Paul (24). Leinster's own Irish duo Sophie MacMahon (47) and Laura Delany (43) were in the runs but never threatened to chase it down, ending 35 short on 134 for 4.

Balbriggan pulled off the shock of the night as they ousted Phoenix by six wickets on their home patch. Gaby Lewis went cheaply and the hosts made a relatively modest 121 for 5 - Nevedha Saravanarajan top scoring with 38 and two wickets for Tess Maritz. The chase was surprisingly straightforward as Lara Maritz took her Super Series isolation out on Phoenix by thumping a quickfire 48, and was well supported by overseas player and fellow Holywood member Madison Landsman - who made 35 as the six wickets win was sealed in the 15th over. Balbriggan will meet Merrion in the last four while the other semi-final will pit Pembroke and Malahide.
