There will be eight Leinster sides in the last 16 of the Irish Cup after a pulsating day's play across Ireland.
Game of the day in the North, was the clash between two of the tournament titans - Donemana and Merrion.
Dom Joyce and Jack Carty both made 72 as they shared a relatively untroubled opening stand of 144 in 28 overs.
Joyce hit 8 fours and a six, while Carty struck 7 boundaries and cleared the ropes three times.
Graham Boyd (3-44) and Willie McBrine (1-43) applied the brakes, and pegged the Angelsea Road side back to 188 for 4.
John Anderson and Patrick Tice (32) were initially watchful before sparking into action. Anderson struck 6 sixes and 4 fours in his 78, with 28 coming off one expensive Cooray over.
The pair added 87 as the Dubliners closed on 295-7 from their 50 overs- a good, but not unbeatable score at the Tyrone village.
Donemana were in early trouble in their reply as Poonish Mehta and Tyrone Kane combined to reduce the hosts to 35-3.
Malith Cooray’s 32 steadied things a little but Donemana needed more and they got it in a superb partnership between Andy McBrine and Gary McClintock. T
his pair took on all comers and they looked to have the double-winners coasting at 250-4; needing just 46 more to win.
McBrine made 90 and McClintock 85, but just as they seemed to be about to post a straightforward win, Kane (3-30) and Mehta (3-45) intervened.
Donemana lost their discipline with the bat when all they needed was to push the ball around and they were given an additional boost when despite countless reminders from the umpires, the visitors were hit with 6-penalty runs at the end of the penultimate over for a slow rate.
Instead of needing 12 off Kane’s last they now needed 6 and with “TK” on the money throughout, it came down to Andrew Riddles needing one to tie and 2 to win off the final delivery, however the bowler found a screamer of a yorker to send the visitors into wild celebration.
You get the feeling that the two-times winners name could well be on the trophy after the belief that a victory of this kind delivers.
Clontarf proved 102-runs too strong for Brigade at Castle Avenue.
Obus Pienaar was heavily involved, not for the first time against a North West side, as his 92 and runs from Waqar Azmat (50), Bill Coghlan (46) and Andrew Poynter (32) helped the home side to 263-7 in their allotted overs.
Johnny Thompson (2-38), Andy Britton (2-52) and Jonny Robinson (2-60) were best with the ball for the Waterside team, but Brigade struggled with the bat in reply.
Thompson’s 59 was by far the best of it with cameosfrom Gareth McKeegan (23) and David Barr (21) at the top of the order-Pienaar having his say again with 3-44 as Brigade were dismissed for 161.
Leinster were pretty much on top throughout as they won at Eglinton and despite a decent effort from the home team with the bat, the southerners had 7 wickets to spare at the end.
Karl O’Doherty (40), Mike Erlank (39) Stuart Thompson (36) and Ross Allen (30) helped the villagers to 217-7 in their 50 while Dockrell, Hamad, and Conaty claimed a couple of wickets apiece.
Ian O’Herlihy (34) and Greth Delany (25) gave the visitors a solid start before Patil chipped in with 37, but the real damage came in an unbroken 106-run partnership between George (64 not out and Joe Carroll (55 not out).
Allen picked up 2-46 as the villagers tried manfully to break through but it is Leinster who advanced to Round 2.
Ardmore fell by the wayside too- Kevin Martin top scoring with 60 for them and Decker Curry adding 34 in a total of 190 at Phoenix Park.
Richie Lawrence (74 not out) and Brad Kneebone (63) saw the home side safely past the target with 6 wickets to spare- Gary Neely’s excellent 2-20 from his 10 overs a top effort in the circumstances.
Another candidate for game of the day was at Malahide where Muckamore came back from the dead to beat the hosts by one wicket in a pulsating contest.
Greg Ford - son of Ireland coach Graham - top scored with 80 from 107 balls (11 fours), sharing a 6th wicket stand of 52 with Irish international Peter Chase (40*) as Malahide posted 212 for 6.
James Newland (5-20) then reduced the Muckamore reply to 48 for 6 before the fightback started.
Craig Drummond shared a 7th wicket stand of 108 with Neil Gill (32), before David O'Halloran (2-13) struck twice to leave the game on a knife edge. Drummond though emerged deservedly on the winning side, clubbing 18 fours and 2 sixes in his unbeaten 108 from just 92 balls to seal the one-wicket win.
Chris Dougherty was another centurion hitting a brilliant 122 as CIYMS ousted five-times champions North County.
The Irish international helped the Belmont side recover from a precarious 33 for 3, sharing half-century partnerships with Ryan Hunter (18) and Jacob Mulder (35).
'Doc' hit 13 fours and a six in his 148-ball stay, helping the Belmont side post 220 - three wickets apiece for Eddie Richardson and Malcolm Nofal.
Nigel Jones (4-32) and Allen Coulter (2-25) reduced the County top order to shreds and Ted Britton (3-10) mopped up the tail in a 107-run win.
There was an excellent away day performance by Balbriggan at The Mall against Armagh.
Colin Russell top scored with 49 as the Premier new boys made 164, with three wickets for Ehtesham Ahmed.
That proved totally inadequate as an opening stand of 91 between Conor Fletcher and Adrian Harper (45) got the North Dubliners on their way.
Fletcher hit an unbeaten 67 as he ensured the 9-wicket win, adding an unbroken 75 for the second wicket with Farooq Nasr (37*).
YMCA are safely through after a routine seven wicket win at home to Cork Harlequins.
It didn't look that way as the Munster men added 113 for the first wicket - Ted Williamson rolling back the years with 75 from 117 balls (10 fours, 1 six).
Matthew Bruster (36) kept Williamson company but once the first wicket fell, the floodgates opened as 10 wickets fell for just 46 runs, Cork dismissed for 159.
Harry Tector claimed 5 for 32, while there were two apiece for Jarred Barnes and Simi Singh.
Singh then blasted 9 sixes and 5 fours in a whirlwind 92 from just 56 balls, as YMCA sealed the win in just 23.3 overs.
Jack Tector (26) and brother Harry (18*) accompanied Singh in stands of 67 and 63.
The Hills and Pembroke were allocated byes bringing LCU representation in the last 16 to eight sides.
