Aberdeen secured their spot in the Betfred Cup final with a 2-0 victory over Morton at Hampden.
Adam Rooney’s 69th-minute header and Kenny McLean’s close-range effort separated the two sides in a tense game.
The Dons will face the winner of tomorrow’s other final four face-off between Rangers and Celtic.
It was a game that at times lacked quality but gives Aberdeen a chance to replicate the success of 2014 next month.
Facing the team where he started his career, Reds manager Derek McInnes was eager to get to another final with his current club.
He made one change to the team that secured 4-0 wins over Kilmarnock and Ross County.
The Dons boss was forced to bring in centre-back Mark Reynolds for the injured Ash Taylor, while skipper Ryan Jack was deemed fit enough for a spot on the bench.
Almost 11,000 Aberdeen fans had made the trip to Hampden and were almost given early cause for celebration.
Less than two minutes were on the clock when Kenny McLean drew a great save from Morton’s Andrew McNeil.
And from the resulting corner, the keeper had no chance as Jonny Hayes flicked a header at goal – only to see it cannon off the bar.
After much pre-match talk about the importance of the first 20 minutes, Aberdeen were keen to capitalise on their strong start.
James Maddison was the architect of the chances for McLean and Hayes and great from set pieces.
But the teenager saw his own pair of efforts miss the target.
And after withstanding the initial 15-minute barrage, the Championship side settled and stemmed the red tide.
McInnes was an animated presence on the touchline, screaming instructions and signalling to his players.
Morton were keen to keep numbers back and tried to quickly catch the Dons on the break.
The long-ball approach just played into Aberdeen’s hands, allowing them to win it back and re-build.
But Maddison’s delicate footwork, McGinn’s opportunistic bursts and Hayes’ raw speed were all unable to unlock the Morton rearguard.
McLean had a couple of pop-shots from outside the area but the Dons struggled to test McNeil.
Large spells of the game were sloppy as neither team looked capable of fashioning a quality chance.
But former Pittodrie prospect Jai Quitongo ensured it wasn’t all going to go Aberdeen’s way, harrying the Dons defence.
If anything, he seemed to try too hard but it was clear he was the Ton danger man and needed careful surveillance.
And just two minutes before the break, Reynolds was unable to corral a Morton thorough-ball, instead diverting it to Quitongo.
The 19-year-old burst into the box but Joe Lewis spread himself well to make a terrific save with his legs.
Adam Rooney had the last word as his effort crashed off the crossbar with the final touch before the break.
Niall McGinn and Jamie Lindsay both picked up yellow cards in a nervy restart to proceedings.
It was Morton who looked the more incisive, with half-chances coming from Quitongo and Kudus Oyenuga.
And it took Anthony O’Connor’s vital interception to end a promising attack after a mistake from the Dons defence.
The attacking fluidity of Aberdeen’s last two wins was notable by its absence, as they offered nothing going forward.
Quitongo saw a vicious 20-yard strike and a close-range bicycle kick fly over the crossbar as O’Connor and Reynolds struggled to cope.
But the hero of 2014 Rooney made up for his missed opportunity at the end of the first half by breaking the deadlock on 69 minutes.
Graeme Shinnie’s cross from the right was flicked back into the middle by Andrew Considine and the Irishman got a good contact to find the top corner.
The Red Army was ecstatic and the Dons pressed on looking for a second to kill the game.
Stand-in skipper Shinnie, Hayes and Rooney all had good opportunities within a five-minute window but could not convert.
Morton manager Jim Duffy implored his team forward but the verve in their play seemed to have disappeared.
Considine was booked for a soft yellow card with five minutes left at which point Aberdeen made their first change.
Creative maestro Maddison was replaced by skipper Ryan Jack, who came on for his first appearance since August.
Hayes saw claims for a penalty waved away late on, with his theatrical fall not helping his case.
But the Dons killed the game off thanks to McLean’s 88th-minute effort.
McGinn broke into the box from the right and his shot was parried away by McNeil – straight into the path of the midfielder.
Aberdeen closed the game out and will face the winner of tomorrow’s Old Firm game on November 27.
