Eglinton spent the day after the night before trying to determine whether they had a right of appeal for their exclusion from the RSA Irish Senior Cup.
North Down were awarded their first round match by the umpires when the home club failed to produce a Duckworth Lewis sheet, which gives the target score in a rain-interrupted match.
The game, like every other tie that started in the North West on Saturday, was delayed and only 15 overs were possible at Eglinton when conditions were deemed match fit.
However, after nine overs, with North Down on 72 for four, the rain returned and play was held up.
When the teams returned, the game had been reduced to the minimum 10 overs per side so the visitors had just one more over before the 10 minutes' change of innings.
Eglinton secretary John Pierce claimed he was not aware of the length of the match until the players came off for the innings break and the club, in their haste to produce a D/L sheet, then ran into computer problems.
Umpires Roly Black and Noel Ward gave them 18 minutes (an extra eight) to produce the sheet before calling time and awarding the game to North Down.
Pierce claimed that a "minute later" the computer was working and a sheet had been produced.
The game at Eglinton was one of 10 that started but only five finished, with the tie at Stormont, between Civil Service North and St Johnston the shortest – only nine balls were bowled – while The Hills were probably the unluckiest, just three overs short of achieving a result against Glendermott when the rain returned to end the contest.
The Skerries side must head north west for the 'replay' on Sunday week, the reserve day for all matches not finished.
With 26 teams (at least) going into the hat, there are sure to be a myriad of either/ors in tomorrow's second round draw but the shock absentees are Donemana, the five-times finalists, most recently back to back in 2008 and 2009.
The North West Cup holders crashed to a 15 runs defeat to a Cork County side which had not won a match in the competition for 11 years.
The game at The Mardyke started on time but rain forced an early end to the first innings, so although the home side scored 171 for eight in 36.4 overs, the Donemana target was 190 in 36 overs.
Any thoughts of a straightforward chase were dashed in the first 16 overs when Donemana collapsed to 46 for four but Andy McBrine, in partnerships with the McClintock brothers, first doubled the score with Gary and then added 55 with William before the Ireland international was caught for 65 from just 49 balls.
He was replaced by his dad, but Junior faced only 10 of the next 26 balls, and when he was leg before for just eight, the last pair of Jordan McGonigle and William McBrine needed 17 from eight balls. They got one from two.
Apart from North Down's 'win', it was a bad day for the NCU with the only three teams to complete a match all losing.
CIYMS came closest but they were 18 runs short with eight wickets down against Coleraine at Sandel Lodge. Chasing 139, they slumped to 72 for seven but Trevor Britton's late rally – he scored 42 runs – gave the North West league champions a slight scare before Scott Campbell claimed his wicket.
Ballymena lost the other all-Ulster clash by an emphatic 91 runs to Bready at Magheramason where David Barr was almost entirely responsible, scoring 82 runs.
Lisburn were unlucky to lose out, not so much to holders Clontarf, but to play in the only prolonged match in Dublin which was actually completed.
In an innings reduced to 20 overs, Clontarf reached their target of 101 with 11 balls to spare.
Ardmore were more fortunate, as rain won the day and they now have a home game against North County but Muckamore must go to Dublin to try again against last year's beaten finalists and 2010 winners Merrion.
