A fourth wicket stand of 114 in 10 overs between Cameron Rowe and Greg Ford powered Balbriggan into the final of the All Ireland T20 Cup in an entertaining match of fluctuating fortunes at The Rectory.
A rain delay meant the match was initially 16 overs per side, with a further shower cutting it a further two.
Irish Under 19 international Scott Macbeth top-scored for the 2021 champions, hitting four sixes and 3 fours in his 46, while Ifty Hussain (39) and Adam McDaid (26) both cleared the ropes three times as Brigade made 130 for 8.
Farooq Nasr (3-20) was inches from claiming a final over hat-trick, while Eoin Birch (2-21) bowled with plenty of fire.
The Leinster champions faced a DLS adjusted target of 133 in 14, and that looked a long way off as Farooq Nasr, Conor Fletcher and Chris de Freitas all fell in the first three overs to leave them on 16 for 3.
It could have been worse with Cameron Rowe dropped first ball off Ryan Macbeth (2-23). Rowe and skipper Greg Ford rebuilt and although the required rate was creeping up, you felt they were biding their time on a ground renowned for its true bouncy wicket and small boundaries.
Still, there must have been a few nerves as they reached 57 for 3 after 8 overs, needing a further 76 from the last six overs.
Rowe and Ford stepped on the gas as the next four overs went for 24, 13, 14 and 17 - a total of 68 in just 24 balls.
Ford went for 43 (1 four, 4 sixes), stumped off Scott Macbeth (2-5), while Matt Pollard fell first ball, but by that stage only four were needed from the last over.
It was fitting that it fell to Rowe to score the winning runs - his fifth four to go with seven sixes in his unbeaten 73.
Balbriggan will have to wait to see who they play in the final at Malahide on August 27th after the CIYMS v Cork County game was abandoned.
