Jason Curry took 3 for 5 as Sion didn't have it all their own way in the chase, but 23 from Havern and a vital 10 not out from O'Neill got them over the line.
Spare a thought for Harry Waterstone who took six wickets to bundle Ardmore out for 60, but a hail shower covered the ground and saw the game abandoned - Brigade too finding conditions tricking as they slumped to 8 for 4 before a mini-recovery took them to 20 before the game was called off.

Marc McCloskey's Man-of-the-Match display helped Bready to a five-wicket win against Fox Lodge. He, Dale McGonigle, and Derek Allen took three wickets apiece as the Foxies made 100 - Lee Finlay (27) and Clive Allen (24) their main contributors.

Sean Hargan hit 55 not out in the win, with Matthew Campbell (2-23) the sole successful bowler for Bready.
In Q3 Paul Britton hit 12 fours and 4 sixes as 72 of his 78 runs came in boundaries, but despite his best efforts Donemana could only make 116 for 8 against Killyclooney. Jason Parkhill took 3-15, while there were two apiece for Keith Buchanan and Andrew Neil.
Killyclooney sealed a five-wicket win thanks to Jordan Nelson unbeaten 54 from 49 balls, which contained 7 fours. Andrew Neil (24) and Evan Barr (18*) chipped in to record the bragging rights in the local derby. Jake Craig (2-10) best with the ball for the Holm side.
