There were wins in the quarter-finals for CIYMS and Instonians in the NCU, as well as Merrion and Phoenix from the LCU.

CIYMS beat Leinster by 5 wickets
Leinster 243 (46.3 overs: Saqib Bahadur 85, Joey Carroll 67, Gareth Delany 20; Carson McCullough 3-65, Tyron Koen 2-30, Bamanye Xenxe 2-41)
CIYMS 244/5 (38.5 overs: Max Burton 82, Tyron Koen 78; Saqib Bahadur 4-45)

Tyron Koen and Max Burton scored half centuries for CIYMS (CricketEurope)

Holders Leinster were knocked out by 2022 champions CIYMS at Belmont. 

The Dubliners were in early trouble at 35 for 4 and 61 for 5, but rallied to 243 thanks to a 6th wicket stand of 109 between Saqib Bahadur and Joey Carroll. 

The stand was ended thanks to Jack Beattie's run out of Carroll who had thumped 6 sixes and 4 fours, while Bahadur top-scored with 85 (10 fours, 2 sixes). 

Bahadur then dismissed John Matchett and Chris Dougherty cheaply, but Tyron Koen and Max Burton soon set about building a match defining partnership. 

The free scoring pair found boundaries at will, with Gareth Delany not featuring in the Leinster attack. 

Koen hit 8 fours and 3 sixes in his 78, while Burton's top score of 82 included 12 fours and 1 maximum. 

The pair fell with the finishing line in sight but the result was never in doubt - the five wicket victory achieved in the 39th over.

Merrion beat Waringstown by 94 runs
Merrion 266/8 (50 overs: Swapnil Modgill 78, Sam Harbinson 73, Michael Lewis 54*; Bilawal Bhatti 5-38, Adam Dennison 2-19)
Waringstown 172 (38.5 overs: Graham Hume 58, James McCollum 52, Matthew Halliday 20; Tom Stanton 3-40, Sam Harbinson 2-21, Mikey O'Reilly 2-38)

Merrion won the 'Big Two' battle as they recovered from a disastrous start to oust 6-times champions Waringstown. 

Having been out in, Merrion lost Stephen Doheny and John Anderson without a run on the board, and Adam Rosslee soon after to be 32 for 3. 

They recovered thanks to a fourth wicket stand of 134 between Swapnil Modgill - who hit 11 fours in his top score of 78 - and skipper Sam Harbinson, who made 73 (5 fours, 2 sixes). 

Mick Lewis hit 9 boundaries in a 38-ball unbeaten 54 to take the home side to a challenging 266 for 8 - five wickets for Pakistan Test bowler Bilawal Bhatti. 

The NCU side's reply got off to a horror start as Tom Stanton accounted for the big 3 of the Topping brothers and Adam Dennison for a combined 3 runs. 

James McCollum and Graham Hume both made half centuries but weren't able to replicate Merrion's salvage operation as the hosts clinched a deserved 94-run win.

Phoenix beat North Down by 7 wickets
North Down 172 (44.2 overs: Alistair Shields 56, Mohammad Aahil 33, James Shannon 23; Jack Lalor 3-42, Ben White 2-23, Amish Sidhu 2-46)
Phoenix 173/3 (34.4 overs: Jack Lalor 48, Levon Shields 41, George Dockrell 31*, Shane Getkate 21*)

Peter Davison is bowled by Jack Lalor (Deryck Vincent)

Phoenix are into the last four thanks to a convincing 7 wicket win over North Down in the Park. 

The NCU side struggled to adapt to the conditions making a below par 172, with Ally Shields top scoring with 56, and Mo Aahil - who scored a hundred in the last round win over Balbriggan - making 33. 

Jack Lalor took three wickets and there were two apiece for Irish international Ben White and left-arm spinner Amish Sidhu. 

Nic Pretorius went cheaply in the reply, but a second wicket stand of 85 between Jack Lalor (48) and Levon Shields (41) broke the back of the chase. 

George Dockrell (31*) and Shane Getkate (21*) easing the Leinster side to victory in the 35th over.

Malahide lost to Instonians by 118 runs
Instonians 199 (50 overs: Nikolai Smith 56, Cade Carmichael 37, Cian Robertson 34, James Lambert 29*; Jeremy Martins 4-22, Kelvin Donnelly 3-35)
Malahide 81 (27 overs: Adam Doyle 32; Cian Robertson 4-23, James Magee 2-11, Andrew White 2-18)

Instonians may be having a tough time in the league but their trip to Dublin was a fruitful one as a fine all-round display saw them beat Malahide by a convincing 118 runs to be the first team into the hat for the semi-final draw. 

Skipper Nikolai Smith (56) top-scored with a dogged half century that was just what his team needed. 

He added 68 with Cade Carmichael (37), while there was another vital half century stand between Cian Robertson (34) and James Lambert (29*) that got them up to 199 - four wickets for overseas professional Jeremy Martins and three for Kelvin Donnelly. 

There was some debate if it would be enough but the Shaws Bridge side produced an excellent bowling display to skittle the Village side for just 81, with Adam Doyle's 32 their best effort. 

Left-arm spinner Cian Robertson took 4-22, while there were two wickets apiece for James Magee and Andrew White.
