CIYMS produced a powerhouse batting display to blow away Cork County at The Mardyke.
The Belmont side hit 20 fours and 12 sixes in an imposing total of 210 for 3.
There were half centuries for Jason van der Merwe and skipper John Matchett, plus runs too for Ross Adair (42) and Chris Dougherty (28).
Van Der Merwe top-scored with an unbeaten 68 from only 26 balls (6 fours, 5 sixes), while Matchett's 57 from 31 deliveries included 6 fours and 3 maximums.
Adair had got his side off to a fast start clearing the ropes 3 times and they never looked back.
Cork's reply was soon in tatters, losing two wickets in the first over - including the wonderfully named Thorne Prophet - slumping to 13 for 4.
Italian international tefano Di Bartolomeo ensured some respectability with 43, while Robert Duggan made 20 as they ended on 111 for 9.
Carson McCullough took three wickets, while there were two apiece for Ed Nuttall and Allen Coulter.
CIYMS will go in search of their third title as they take on Balbriggan at Malahide on Sunday August 27th.
