Leinster Lightning Bolts strengthened their position at the top of the Future Series table when they proved too strong for Ireland Under 19s at Oak Hill to win their fourth game on the spin.
Skipper Mitchell Thompson scored a run-a-ball 51 as the Dubliners posted 217, with Alistair Frost making a patient 47, although he accelerated towards the end, hitting two sixes.
There were also useful contributions from JJ Garth (24) and opener Jamie Grassi (22).
Left-arm paceman Diarmuid Burke claimed three wickets for the teenagers, while Muzamil Sherzad took two wickets.
Ireland Under 19s once again struggled with the bat, as YMCA left-arm paceman Mikey O'Reilly removed Claremont Road team mate Henry Thompson and Nathan McGuire for six apiece.
U19s skipper Tim Tector steadied the ship with an unbeaten 36, but none of his colleagues hung around for long, as Amish Sidhu (2-11) dismissed Ewan Wilson (15) and Phillipe Le Roux (12).
A shower meant a DLS adjusted target of 205 in 39 overs, but it was a notional one as Gavin Hoey (1-9) trapped James Forbes lbw, then Rory Anders (2-14) accounted for Luke Whelan and Matthew Humphreys in quick succession to leave Ireland reeling on 96 for 7.
Further heavy rain brought proceedings to a close, with Bolts declared 65-run winners on DLS.
No play was possible in the scheduled game between Munster Heat and the Emerging Warriors at North Kildare.
The series continues next week with Ireland U19s playing three matches, while the Bolts will all be assured of the title if they win both their away games against the Knights and Munster.
