It as a tough day for the North West Under 15 bowlers as they were on the wrong end of some dominant batting displays by Leinster and the NCU at Derriaghy.
Leinster skipper Aaron Doyle made it two hundreds in two days as he hit 12 fours and 5 sixes in his 114 from 70 balls as they posted a daunting 181 for 2.
He shared a second wicket stand of 115 with Pembroke's Macdara Cosgrave (35) and dominated a unbroken third wicket partnership of 57 with Olly Riley (4*).
Gavin Roulston (1-13) escaped the carnage, while the other wicket takers were TJ Boyd and Matthew Collum.
The NW reply never got going as Srihan Karpe (3-15) struck three early blows including the prize scalp of Roulston.
Abdul Quyaan struck six boundaries in a defiant 28, but the game was long gone by that stage, as they finished 102-runs adrift on 79 for 8.
It was a similar take in the afternoon game against the champions, NCU.

An opening stand of 107 between the prolific Ryan Hunter (51) and Finn Lutton (49) set the hosts on their way.
Skipper Harry Dyer then inflicted more punishment on the beleaguered North West attack as he hit 5 fours and 5 sixes in an unbeaten 71.
88 runs came from the last five overs as the NCU racked up 211 for 4 in their 20 overs.
Gavin Roulston impressed in the chase with 51 not out (6 fours, 2 sixes), as he and Stephen Magowan (22) added 54 for the second wicket.
The NCU used ten bowlers as the visitors finished on 111 for 4, losing by exactly 100.
Harry Dyer was presented with the trophy by Albert van der Merwe after the game.
