Lawrence Shankland enhanced his World Cup credentials with a clinical second-half brace as Scotland came from behind to defeat 10-man Curacao 4-1 in their final Hampden Park outing before travelling to the United States.
Fresh from completing his summer move from Hearts to Rangers, Shankland delivered a match-winning performance to help Scotland record their first home victory in a friendly fixture for 10 years.
The visitors threatened to spoil the farewell occasion when former Manchester United winger Tahith Chong produced a brilliant solo goal to put Curacao ahead.
However, the contest shifted dramatically before half-time when striker Jurgen Locadia was sent off for catching Aaron Hickey with a stray forearm.
Scotland quickly capitalised. Finlay Curtis, who had only recently replaced the injured Billy Gilmour, marked his arrival with a composed finish for his first international goal, drawing the hosts level just before the break.
After half-time, Steve Clarke's side took control.
Tyler Fletcher, son of former Scotland captain Darren Fletcher, made his senior debut before Shankland took centre stage.
The striker first converted from a well-worked corner routine and later finished emphatically after being released by Lyndon Dykes, further strengthening his case for a starting role at the World Cup.
Curtis continued to impress and won a late penalty after being brought down inside the area, allowing Ryan Christie to complete the scoring from the spot.
Scotland now head to the United States, where they will face Bolivia in New Jersey on 7 June before opening their World Cup campaign against Haiti in Boston a week later.
Steve Clarke had described the match as a useful test ahead of facing Haiti, a side ranked just below Curacao in the FIFA standings, and the visitors proved awkward opponents for long periods.
Chong's stunning opener exposed Scotland's defensive vulnerabilities.
After controlling a long pass brilliantly near halfway, he surged beyond John Souttar, cut inside and fired past Craig Gordon to silence Hampden.
With key figures such as Scott McTominay, John McGinn, Lewis Ferguson, Che Adams and Kieran Tierney rested, several fringe players were given the opportunity to impress.
Few managed to seize it early on, but Curtis certainly did.
The teenager responded superbly after Gilmour limped off with what appeared to be a knee injury.
Combining neatly with Kenny McLean, Curtis calmly slotted his finish into the far corner to restore parity and inject life into Scotland's performance.
Shankland then demonstrated why many view him as Scotland's most natural finisher.
His first goal showcased intelligent movement and anticipation from a set-piece, while his second highlighted his composure as he guided a precise finish in off the post after an excellent pass from Dykes.
Curtis was influential throughout the second half and capped an impressive display by winning the penalty that Christie converted.
While concerns remain over Gilmour's fitness, Clarke will be encouraged by the sharpness shown by returning players such as Hickey and Ben Doak, as well as the impact made by emerging talents like Curtis.
Most importantly, Scotland head to America with momentum, four goals, and growing confidence as they prepare for their first men's World Cup appearance in 28 years.
Scotland manager Steve Clarke: "I wasn't happy with the start. The game didn't reflect how well Curacao actually played, the scoreline ran away from them a little bit. At 11v11, we had a little bit of work to do.
"We had to get a lot of players on the pitch just to give them a chance to play again. Quite a lot of them haven't had many minutes through the second half of the season, and I think that showed towards the start of the game.
"We're not too sure how bad Billy Gilmour's injury is right now. He will be assessed overnight, fingers crossed that the wee man is fine.
"I said already, it will be a squad tournament, not just a starters tournament, so next week is about getting used to the climate and the heat, and then for 60/65 minutes there will be a strong side out against Bolivia."
Scotland goalscorer Findlay Curtis: "I'm buzzing, it's everything I've dreamed of, I'm delighted to get that spot in the World Cup.
"My mum and dad are in Tenerife, I booked for us all to go, and then I couldn't go, so they'll be over there watching with pride. I can't believe everything that's going on at the minute, I just need to soak it all in."
Scotland goalscorer Lawrence Shankland: "We wanted to go to America on the back of a win and it was important we got that.
"The start of the game was quite difficult and we got fortunate with the red card but after that, we looked like the only team that was going to score.
"Every goal you score for your country, you're delighted. It's a special day, I had my kid as the mascot as well."
