Leinster will have three representatives in the semi-finals of the RSA Irish Senior Cup after an action packed day around the grounds.

Andrew Poynter hit an unbeaten 195 - the second highest individual score in the 33 year history of the competition - as he and teenager Colin Currie (91*) added an unbroken 296 for the third wicket to take Clontarf to 315 for 2 against Donegal side St Johnston.

This was Poynter's second successive century over the weekend, and also his and Currie's second consecutive unbroken double hundred partnership, taking their tally to an unbroken 514!

Zander van der Merwe claimed four wickets as the St Johnston top order was blown away - 23 for 6 at one juncture.

A late order rally did earn them some respectability, as they finished on 152 all out.

Pembroke held their nerve to edge out Merrion in another thriller between these two familiar Dublin rivals.

Tyrone Kane (36) top scored in their total of 204 for 8 - no fewer than 9 players reached double figures, but nobody was able to make the decisive contribution to get them to 250.

When Pembroke slumped to 62 for 5 it looked as if Merrion would prevail, but another pair of young players came to the Sydney Parade sides rescue.

Barry McCarthy (64) and Lorcan Tucker (51) shared a 6th wicket stand of 107 to give their team a great chance.
Despite a few nerves along the way, Pembroke got over the line with 7 balls to spare, with Conor Mullen (18*) and Fiachra Tucker (15*) the heroes at the death.

There was another tense affair at Park Avenue where 2012 winners The Hills showed all their big match experience to oust Railway Union.

Railway managed only 148, and even that modest total was mostly due to Saad Ullah - the middle order batsman hitting 4 sixes and 4 fours in his 60 from 55 balls.

Manu Kumar (4-15) took the bowling honours for The Hills , with Max Sorensen (2-33) and Mark Dwyer (2-40) also doing well. Special praise to Naz Shaukat who conceded just 7 runs in his miserly 10 over spell.

Patrick Byrne's half century looked to have set up Hills for the win, but Railway kept plugging away and at 115 for 7, looked as if they would prevail.

The Hills love a battle though, and often save their best performances in this competition. They dug deep yet again and crept over the line with two wickets and four balls to spare.

There was a high scoring thriller at Coleraine where North Down chased 303 to win by five wickets.

Niall McDonnell top scored with 103 from 116 balls (11 fours) as the Bannsiders racked up 303 for 4. Kyllin Vardhan (84), Scott Campbell (52) and David Cooke (42*) all batted well to take advantage of an excellent pitch and fast outfield.

James Cameron-Dow (3-49) was the one stand out bowler for North Down.

The North Down top four all got starts - the quartet reaching 44, but none going on to make 50, but they had laid the foundation for the successful chase. Johnny Terrett (47), Nick Larkin (46), Ryan Haire 45, and Andrew Sutherland (44) the aforementioned top order.

Ireland Under 19 player Peter Eakin enhanced his reputation as a serious impact player by blasting 60 from 39 balls (2 fours, 4 sixes), as he and Taimur Khan got North Down close to victory, with Ally Shields finishing the task, as the Comber side won by five wickets.

The semi-final draw will take place tomorrow (Tuesday) during the lunch interval of the Newstalk Inter-Provincial Championship clash between Leinster Lightning and North West Warriors at Malahide.
