St Vincent's 2-12 Mullinalaghta 0-11
Shane Carthy continued his strong form for St Vincent's scoring 1-03 at Glennon Brothers Pearse Park to secure an anticipated AIB Leinster club senior football championship final berth for the Dublin kingpins.
The 2013 and 2014 provincial winners maintained their recent pattern of playing well within themselves but still doing enough to win with some to spare.
The seven-point winning margin flattered the Dubliners as midfielder Carthy scored his goal in the 59th minute and added a point in injury-time.
Vincent's led by just three points before that goal, 1-11 to 0-11, and found the small Longford club a tough nut to crack in perfect conditions at the midlands venue.
Carthy's excellence and 1-02 from veteran Tomas Quinn ultimately proved vital and Vincent's advance to play Rhode of Offaly in the 11 December final, a repeat of the 2014 decider.
Hosts Mullinalaghta were themselves attempting to make history by becoming the first Longford club to reach the provincial decider.
They were given little hope of doing so by neutrals despite overcoming the Laois and Westmeath champions previously but - perhaps inspired by Longford's O'Byrne Cup win over Dublin at the same venue in January - pushed Vin's hard for almost the full hour.
Both sides scored eight times in the first-half with Quinn's 16th-minute goal tipping the balance Vin's' way at the break when they led 1-07 to 0-08.
That goal came against the run of play as Mickey Graham's Mullinalaghta started well and led 0-03 to 0-02 when Quinn struck from close range to palm the ball in after Enda Varley's probing run down the right and hand pass.
Mullinalaghta points from Rian Brady, his second, James McGivney and Shane Mulligan represented a strong response and they led again with 20 minutes on the clock, 0-06 to 1-02.
But Marino outfit Vincent's finished the half strongly with five points in the closing minutes including two converted Quinn frees to take that interval lead.
There was just two points scored, one from each team, in the first 20 minutes of the second-half and the outcome hung in the balance.
But Vincent's showed their All-Ireland title winning experience by finishing strong and enjoyed a strong impact from their bench with scores from subs Albert Martin and Joe Feeney opening up a three-point advantage before Carthy's late heroics.
