Two goals from Ryan Thomson helped Dunfermline Athletic demolish neighbours Cowdenbeath in a game that emphasised the gap in class between a side relegated from the Scottish Premier League and the Division Two champions.
Andrew Barrowman and Josh Falkingham also struck for Jim Jefferies' side at Central Park to get the Pars' Division One campaign off to an ideal start.
Striker Barrowman showed his predatory instinct to edge the Pars ahead on the stroke of half-time as he netted from close range to follow up his goal at Forfar in the Ramsdens Cup last time out.
Dunfermline doubled their advantage four minutes after the restart when midfielder Thomson met Alex Whittle's delivery from the right to nod past Thomas Flynn.
Thomson was again on the scoresheet 11 minutes from time as he converted Falkingham's pass into the top corner from close range.
Falkingham completed the rout with a stunning strike from 25 yards.
