The action switched to T20 mode on Wednesday when Ireland recovered from a disastrous start, slumping to 21 for 5 to fight back strongly.
YMCA's Wilhelm De Klerk thumped 9 fours in an unbeaten 71, sharing a 6th wicket stand of 111 with Ben Brownlee (34*) as the Boys In Green posted 132.

In the afternoon game Matthew Humphreys claimed 4 for 18 to restrict Berkshire to 101 for 8.
Jack McGee and Matthew Daly were both run out to leave Ireland 2 for 2.
Nathan McGuire (23) started the recovery, and the YMCA pair of Tector (35*) and De Klerk (30*) added 70 for the fourth wicket to seal the 7-wicket win.
Ireland have the chance to complete a clean sweep when they take on Berkshire in a 50-over contest today, once again at Merchant Taylors school.
