Ross Crick returned to Coca-Cola Combination action by hitting a hat-trick, Dave Brodie and junior Calum Brennan both scored fine goals while Barry Beatson conceded an own goal as under-strength Trinity fell apart to ship three goals in the final 15 minutes.
The win lifts Scottish three points clear at the top from two games more played than Grouville, while Trinity dropped to fifth on goal-difference behind champions St Peter and 12 points behind Scottish, albeit with two games in hand.
Scottish were crisper with their passing and brighter with the running, while Trinity, who had a bundle of players missing and a makeshift central defensive partnership of brothers John and Barry Beatson, gallantly fought on, but they were out of the depth in the end.
Trinity conceded six goals for the third time this season, the second time in the league, while the other was in the Charity Cup final against St Peter.
Trinity manager Joe Morley said: ‘We were not good enough on the night – it’s as simple as that.
We had a lot of key players missing and several others are down on their form.’ Scottish manager Pat Brennan, said: ‘We played really well.
Yes, Trinity had a load missing but you still have to take advantage.
‘We were in the same position in September and you have to get on with it.
We dropped points to Grouville and St Ouen and hopefully they will not prove too costly in the run-in.
‘Craig Ferey and Scott Devlin were outstanding; that made us solid at the back.
Ross scoring goals again was also tremendous, I’m delighted for him because he has had such a hard time.
‘One other person deserves praise too and that’s Dave Kennedy.
He has been helping with our coaching and what a great motivator he is.
He’s a diamond and I wish I was half as good as him.’ Scottish took eight minutes to break the deadlock when Crick lifted the ball over Jimmy Styles from 12 yards after Lee Burns’ left-wing cross.
Crick made it 2-0 on the half hour when he beat Styles on his near post following skilful player from junior Jack Boyle.
Trinity’s best chance resulted in an excellent blocked challenge from Ferey to deny Jon Fitzmaurice.
Boyle went close after the interval while Scottish goalkeeper Gareth Bayley cleared with a foot to thwart Stephen McCarter.
Boyle and Crick missed further chances before Barry Beatson nodded Burns’ free kick into his own goal.
Trinity left Crick unmarked for him to lash home number four from ten yards.
Trinity had chances with Bayley saving twice before Brodie dropped a shoulder to run on and score a fine fifth.
Brennan’s son Calum completed the rout with a deft header from 14 yards.
