Merrion and Clontarf remain on course for a title showdown after both completed comfortable wins at the weekend.
Leaders Merrion romped to an 8-wicket win at home to The Hills with skipper Dom Joyce leading the way as they chased down 143.
Joyce hit 12 boundaries in his 76 from 83 balls, sharing a century opening partnership with professional Poonish Mehta (40).
Nic Pretorius (55) and Albert van der Merwe (31) shared a third wicket stand of 55, but a final total of 143 proved woefully inadequate.
Tom Stanton (3-32) and Dave Langford-Smith (2-17) were the pick of the bowlers.
Clontarf stayed in contention as they showed no ill effects following their cup success the previous day.
In a 32-over game Pembroke rallied late as Paul Lawson's 37 from 26 balls got them to 178 for 6 - two wickets each for Poynter and Dutt.
There were a few nervous moments for Clontarf as wickets for Jack Balbirnie and Fiachra Tucker had them at 117 for 5 in the 24th over.
Enter the man of the weekend, Bobbo Forrest, who hit an unbeaten 55 as he and Conor Kelly (18*) knocked off the total with 10 balls to spare.
An opening stand of 122 in 17 overs between skipper Jack Tector (64) ad Oliver Gunning (57) helped YMCA post 210 in a 30-over match - three wickets apiece for Joe Carroll and Bilal Azhar.
A second wicket stand of 102 in 92 balls between Monil Patel (61) and Hugh MacDonnell (48) gave Leinster hope, but three wickets from James Parkinson saw them fall 15 runs adrift.
Stephen Doheny's 68 kept Rush's promotion hopes alive as they overcame Balbriggan by 17 runs in a 20-overs game, while champions Malahide beat bottom side Terenure by 7 wickets.
