Phoenix finished top of Group D after a ruthless 10-wicket home win over Railway Union. A fourth wicket stand of 70 in eight overs between Mark Canniffe (46) and Connor Walden helped Railway to 143 for 6 - two wickets for Amish Sidhu.

The target proved no trouble to Phoenix thanks to an opening stand of 144 in 13.4 overs with Shane Getkate hitting 8 fours and 3 sixes in a 45-ball unbeaten 69, while Eknoor Singh almost matched him blow for blow with his 68 not out from 41 deliveries (7 fours, 3 sixes).

Merrion ran out comfortable eight-wicket victors over Civil Service at Anglesea Road. Simranjeet Singh made 57 (6 fours, 2 sixes), adding 65 for the third wicket with Amkh Gusain (29) in a CS total of 142 for 6.

Stephen Doheny and Adam Rosslee put a huge dent in the target with an opening stand of 114. Doheny hit 7 fours and 4 sixes in a rapid 37-ball 71, while Rosslee's 25-ball 47 (5 fours, 2 sixes) was also pleasing on the eye. Both fell to Aamir Bafanda, but that was the last success as Swapnil Modgill's 22 not out sealed the win in the 12th over.

Rush finished Group C on a winning note beating Adamstown by 40 runs. Hashir Sultan top-scored with 56 from balls (5 fours, 2 sixes), while Abidullah Taniwal 23-ball 41 (6 fours, 1 six) helped them to 171 for 5 - three wickets for Bradley Fernandes.

Prabhanshu Kamal made 35 in the chase, but two wickets apiece for Conor Butterly and Alex Neary restricted them to 131.

The Hills secured a semi-final berth with a ten-run win in the winner takes all clash against Clontarf at The Vineyard. Victory was set up by a second wicket stand of 116 in 69 balls between top-scorer Oliver Horlock - whose 50-ball 71 included 7 fours and 4 sixes - and Nathan Rooney, whose made a 41-ball 58 (5 fours, 3 sixes) in a total of 172 for six.

John McNally took two wickets and it was the tall left-hander who led the Clontarf reply with a fluent 47 (8 fours). Eoghan Delany (31) and Fionn Hand (21) kept Clontarf in the hunt, but The Hills prevailed thanks to two wickets apiece from Sean McNicholl, Cian Nulty and Febin Manoj.

There was an entertaining game at Balrothery with four half centuries and a last-ball win for North County in the derby clash with Balbriggan. Jordan Hollard made 69 ( 4fours, 4 sixes) and Greg Ford 65 (8 fours, 2 sixes) in an opening stand of 137 in 14.2 overs, while late runs for Sebastian De Oliveria (22*) took Balbriggan to 181 for 5 - three wickets for Eddie Richardson.

The North County innings followed a similar pattern as Jamie Grassi 51 (4 fours, 4 sixes) and Hunter Kindley 50 (5 fours, 2 sixes) put on 91 for the first wicket. The game was right in the balance up the death with Richardson's unbeaten 30 decisive, hitting the last ball to the boundary with two needed.

Robbie Foulkes all-round efforts were instrumental as Malahide reached the last four with an emphatic 8-wicket win over North Kildare. His four wickets kept the visitors to a modest 117 for 7.

He then hit 7 fours and 2 sixes in an unbeaten 60, adding 55 in six overs with Jeremy Martins (28), while there were also runs for Matt Ford (20*) as they clinched the win in the 15th over.

Holders Leinster advanced safely into the last four as they topped Group A courtesy of a 50-run win at home to Dublin University. Monil Patel top-scored with 94 (10 fours, 6 sixes) adding 64 for the second wicket with Younas Ahmadzai (54) and 78 for the third with Tom Johnson (18) as the Rathmines side made 199 for four.

Rory Betley raced out of the traps with a hard-hit 68 in 37 balls (9 fours, 3 sixes) as 67 came in the powerplay. Jamie Forbes chipped in with 40 not out (5 fours), but five wickets for Devan Keenan ensured an ultimately comfortable 50-run win.

Pembroke finished on a winning note as they beat a spirited Terenure by four wickets at Sydney Parade. Zeeshan Mumtaz made 32 in what looked like a modest total of 122 - three wickets for Olly Riley and Joe Prendergast, plus two for Blake MacDonald.

Danny Hogan thumped four sixes in a quickfire 37, but Jinal Khatri' four wickets reduced Pembroke to 83 for 6. Joe Prendergast and Ollie Riley ensured the win with each making unbeaten 30's. 

Finals day will be held at Sydney Parade on Saturday July 12th, with Leinster taking on Malahide, the winners facing either The Hills or Phoenix - who play at Anglesea Road - later in the day for the right to represent Leinster in the All-Ireland T20 semi-finals.
