Instonians are the NCU Under 15 league champions after winning a thrilling decider against rivals CSNI at Stormont.
George Palmer's brilliant 54 from just 32 balls (4 fours, 3 sixes) got Inst off to a fling start as he shared an opening stand of 65 with Ben Oberholzer (19).
Tom Crothers kept the momentum going as he made a quickfire 34 from just 19 deliveries (5 fours, 1 six), and they looked on course for 150 plus.
Three wickets for Harry Dyer, and two for Adam Leckey pegged them back in the final stages, and a final total of 133 for 6 was considered par.
