Match ends, St. Johnstone 3, Hibernian 0.
St Johnstone grasped a great opportunity to win their first ever League Cup, says manager Callum Davidson, after his side stunned favourites Hibernian in the semi-final.
Jason Kerr and Shaun Rooney bulleted in headers either side of the break to put them in control.
Craig Conway sealed victory and a meeting with either Livingston or St Mirren in the final on 28 February.
"The Old Firm have dominated the cup competitions," Davidson said.
"So when you get that opportunity you've got to try and take it. First-half they dug in, second-half they took it.
"I'm just delighted we managed to get through. Now we've a chance to win a trophy this season."
It will be only the Perth club's third League Cup final, having last got to the tournament's conclusion in 1999, where they lost to Rangers.
History, plus a 17-point gap between them and Hibs in the Scottish Premiership, meant this result was not in the script, even if St Johnstone's results this season belie their performances.
There was no doubt, though, the absence of the Old Firm and Aberdeen meant that Hibs were favourites to lift the trophy, and in truth could have booked a return trip to Hampden by half-time.
After a cagey opening, Jack Ross' side carved open excellent opportunities but failed to take them, and Jamie Murphy had the best two within seconds of each other.
Alex Gogic's cross was helped into his path right in front of goal, but his side-footed effort was blocked by Zander Clark before he clipped the rebound onto the bar. It was the starkest example of Hibs' profligacy, but not an isolated incident.
Jackson Irvine powered two headers goalward, but one flew wide and the other rattled the outside of a post, and Paul Hanlon also forced Clark into action moments before Murphy's gilt-edged opportunities.
St Johnstone offered little during those first 35 minutes, but were clinical in capitalising on their first corner of the evening. David Wotherspoon curled in a fantastic corner which Kerr thundered into the net, outmuscling Ryan Porteous as he went.
Despite their goal, the Perth side retreated ever deeper and needed to hold onto possession better and get more support up front to get some respite, with striker Chris Kane often isolated.
But just four minutes into the second half, they struck a brutal blow through another bullet header from Rooney. Again the delivery - this time from Conway - was as exquisite as the Hibs' marking was poor.
Rather than sit deep this time, St Johnstone had no intention of settling for 2-0, as they swelled in confidence and piled further pressure on Hibs.
Rooney, playing at right wing-back, was at the heart of it as he frequently drove into the box to wreak havoc, none more so than for the third goal, when he cleverly picked out Conway to tap home to effectively seal victory with a full half hour still to play.
Man of the match - Shaun Rooney
What did we learn?
St Johnstone can score goals. A lack of them has meant league results have not matched performances, but all three strikes at Hampden were fantastic. Kerr and Rooney's headers are as good as you are likely to see all season, and the third was terrifically well-worked.
After riding their luck for the opening 35 minutes, Davidson's side grew in confidence, and often exposed Hibs' left channel in attack, while retreating back into their solid back five with expert efficiency when required. It was a thoroughly deserved triumph.
As for Hibs, this is a horrible blow. They have now lost two semi-finals in the last three months, and all five since they lifted the Scottish Cup in 2016.
Ross keeps talking about progressing the club by ensuring they compete for trophies and European places, so a retreat to the old fragile mentality on the big occasion must be of great concern. This cup was there for the taking.
Their narrowness in attack made life easier for St Johnstone's back three than it might have done, and once behind they could not come up with any answers to change the momentum of the game. That said, if Murphy had buried one of his two attempts, it's a different game.
What they said
St Johnstone manager Callum Davidson: "I thought Hibs were the better team first-half, especially for the first 35 minutes. We rode our luck a little bit. We dug deep and it allowed us to go and get a result."
Hibernian head coach Jack Ross: "We didn't deserve to be behind at half-time but we were. We lost our way badly in the second-half, our reaction to conceding the second goal wasn't good enough."
Both sides are in Premiership action on Wednesday, with St Johnstone hosting Aberdeen (18:00 GMT), and Hibs welcoming league leaders Rangers to Easter Road (19:45).
