St Vincent's first-half wind-assisted blitz enabled them to beat holders Crossmaglen 2-9 to 0-11 in Sunday's AIB All-Ireland Club semi-final at Navan.
Brian Maloney's second-minute goal and Tomas Quinn's strike helped the Dublin outfit lead 2-8 to 0-4 at half-time.
Helped by the breeze, Cross cut the lead in the second half but they never really looked like getting on terms.
St Vincent's set up a decider against Nemo Rangers with a degree of comfort despite scoring one second-half point.
Oisin McConville top-scored with four points for Crossmaglen but the injury-affected Armagh star struggled to make an impact in open play.
Crossmaglen boss Donal Murtagh introduced Francie Bellew early in the second half but the Armagh full-back appeared to pick up an injury during the closing minutes of the game, as he was noticeably hobbling.
606: DEBATE
Helped by a strong breeze, St Vincent's were four points up after only two minutes with Brian Maloney slamming in a goal after a long ball from the excellent Tiernan Diamond.
Oisin McConville opened Crossmaglen's scoring in the seventh minute but the superb Dermot Connolly responded immediately with another Vincent's score.
John Murtagh's point cut Vincent's lead to three but the Dubliners responded by hitting an ultimately decisive 1-3 without reply.
The direct ball was causing havoc in the Cross defence and the aerial route led to the second goal on 14 minutes with Tomas Quinn firing to the net after a lay-off by full-forward Pat Gilroy.
St Vincent's outscored Crossmaglen 0-4 to 0-2 in the remainder of the first half which extended their lead to 2-8 to 0-4 at the interval.
Predictably, Crossmaglen summoned up a big effort after the break with two quick points.
The holders also felt that they should have been awarded a penalty when Johnny Murtagh appeared to be hauled down but, in truth, Vincent's had also been denied a blatant spot-kick in the opening period.
By that stage, Michael McNamee had been introduced for Martin Aherne while Bellew was soon on in place of Stephen Clarke.
Dermot Connolly replied with a Vincent's point which proved to be the Dubliners' only score of the second half.
Crossmaglen hit five points without reply in the final 20 minutes of the match but without a goal, they were never scoring points at a fast enough rate to get back on terms.
Tony McEntee's point a minute from time cut the lead to four and goalkeeper Paul Hearty even stormed upfield a la Peter Schmeichel in the closing seconds as Crossmaglen attacked.
But crucially all the best individual performances had been produced by Vincent's players with midfielders Hugh Coghlan and Michael O'Shea both standing out.
