Pembroke opened their campaign with a 31-run win over Clontarf at Sydney Parade. Louise Little got the home side off to a quick start with a rapid 23 as she and Sarah Forbes shared an opening stand of 42.

They collapsed once again in the search for late runs, losing seven wickets for 14 to be all out for 122 - two wickets apiece for Alyssa Pasley, Alice Walsh and Lucy Barry. The Clontarf chase never really got going despite a run-a-ball 36 from Julie McNally (3 fours). They were bowled out for 91 with a brace apiece for Mhairi Nicholl, Hannah Little and Kimli McDonald.
