Goals from Nathan Patterson and Che Adams saw Scotland beat Moldova 2-0 to earn Steve Clarke's side a place in the play-offs for the 2022 World Cup
Patterson gave the visitors a crucial lead seven minutes before half-time and Adams doubled their advantage with a simple far-post finish after 65 minutes
The visitors still needed to rely on goalkeeper Craig Gordon, who saved Vadim Rata's VAR-awarded penalty eight minutes from time, to avoid a nervy finish at the Zimbru Stadium
Scotland's win - their fifth in a row in all competitions for the first time since 2007 - means they are guaranteed to finish second in Group F and with it a place in March's play-offs, where they will be seeded if they beat group-winners Denmark at home in their final qualifier on Monday night
Scotland arrived in Chisinau knowing they could not afford any costly slip-ups against opponents ranked 181 in the world if they wanted to guarantee second spot in Group F and with it a play-off place for the 2022 World Cup - and that is exactly what Clarke's men did, with a thoroughly-professional display
The visitors dominated the early exchanges and thought they had taken a third-minute lead when Adams collected Andy Robertson's cross and turned his man in a tight space before finishing calmly, only for the flag to go up for offside in a tight decision confirmed by the VAR
However, despite being on top for the first quarter of the game, Scotland still had to rely on Gordon's reflexes to keep the scoreline goalless as the goalkeeper produced a stunning save to keep out Artur Ionita's close-range header
That stop proved even more crucial when Clarke's team opened the scoring with a well-worked goal involving John McGinn, whose nice lay-off released Patterson in the box and the full-back then did brilliantly to find the bottom left-hand corner of the goal, the first Rangers player to score for Scotland since Steven Naismith against Lithuania 10 years ago
The visitors still needed a second goal to be confident of victory and that breathing space came after another fine move involving McGinn, with the Aston Villa midfielder's clever back-heel releasing Patterson into the area and, from his low cross, the unmarked Adams was there at the far post to side-foot home for his first Scotland goal in eight games
But Scotland never do things easily and, after Patterson had inexplicably handled in the area, the referee was advised to look at the incident on the pitchside TV monitor, before pointing to the spot
However, Gordon guessed correctly and dived to his right to keep out Rata's well-struck spot-kick before Kieran Tierney reacted quickest of all to clear the rebound, seconds before the penalty taker could tap home into an empty net, to ease any Scottish nerves
Patterson produced another accomplished display in Chisinau to help Scotland to victory, scoring their vital opening goal to calm the visitors' nerves, before setting up a second after the break that Adams could not miss as he confirmed his importance in this side
The Rangers right-back showed great composure to make the breakthrough seven minutes before half-time with a finish Ally McCoist would have been proud of as he incredibly became the first player from Ibrox to score for Scotland since Steven Naismith against Lithuania 10 years ago
And the 20-year-old's penetrative burst into the box helped lay a goal on a plate for Adams midway through the second half, exactly the type of run his manager would have wanted from his wing-back
 "I think it was a good performance on the night: going forward, trying to create chances
 A lot of shots but only two goals
"Obviously the penalty at the end could have made it a little bit nervous but when you need him Craig is always there to make the save
"He made one really good save in the first half and one in the second half
 So a good contribution from everybody, and obviously we're pleased to get the second position and now we have a game against Denmark and all our focus goes to that
"We said we wanted to get to the November games being competitive, with a chance of qualifying for the World Cup, so we're still on track for that
"We recognise the Danes have been the best team in the group but with a full house at Hampden we have the chance to go there and hopefully do ourselves justice in what should be a cracker of a match
""It was a comfortable performance from Scotland, who were in total control
 Yes Moldova missed a penalty and had the chance in the first half which Craig Gordon made the save from
"But you had the feeling Scotland could go and score four or five goals if they really wanted to
 They were unlucky with a few offside decisions, but it was a comfortable performance from Scotland and one that will please Steve Clarke because when you go back to last month with the Faroe Islands performance, which was not great, but they managed to get the result
"Tonight was pretty straightforward though…"Moldova travel to Austria, while Scotland host Group F winners Denmark, with both sides' final games kicking off at 7
45pm on Monday, and you can see the Scots' clash live on
