Curtis Moorehead (2-31) removed Delany and Danny Hogan in consecutive balls as the contest ebbed and flowed.

In the Knights innings John Matchett underlined his burgeoning reputation with a flowing 69 (4 fours, 2 sixes) as they posted 183 for 9.
James McCollum and Jamie Holmes both chipped in with 20 apiece, but Pembroke leg-spinner Fiachra Tucker's 3-23 threatened to derail the Knights innings as they lost wickets at regular intervals.
Carrickfergus all-rounder Alex Haggan's late salvo of four sixes in an entertaining 36 ensured a competitive total, with Gareth Delany, Tom Stanton and Tom Anders all picked up a brace.
The series saw two great games between the younger representative players from each of the Unions.
The Knights and Lightning coaches Simon Johnston and Albert van der Merwe have already indicated that they regard this kind of fixture as vital to player development and something that should be repeated. No doubt the success of the games so far will ensure their continuation in the future.
