Hat-tricks remain relatively unusual - even for the deadliest of strikers. Fordyce, though, is a 21-year-old defender who rarely ventures into the opposition box, but on Saturday he scored three times and all with headers.
"It's a once in a lifetime thing for me," said Fordyce. "I was lucky to be in the right place at the right time for all three. It's the first hat-trick of my career and will probably be the last."
Andy Barrowman and Mark Burchill also netted for the victors, after Kane Hemmings put the visitors ahead.
Hamilton Academical were licking their wounds after a first defeat of the campaign against Alloa Athletic. Alex Neil, the player-manager, accepted much of the blame, having handled Jason Marr's header on the goal-line and being ordered off before Ryan McCord netted the decisive penalty.
Neil said: "My sending off changed the game. Up to then I thought we had dominated and had the best chances."
Dundee brought Morton back to earth with a 3-1 win at Dens Park - former Cappielow striker Peter McDonald scoring twice as his old team-mates suffered the effects of their midweek exertions in beating Celtic - while Queen of the South suffered a second consecutive home defeat, Garry Fleming's late goal giving Dumbarton the points.
Dunfermline Athletic had an impressive 5-1 win over previously unbeaten Ayr United in League 1.
East Stirlingshire enjoy a four-point cushion at the top of League 2 after Michael Bolochoweckyj's goal was enough to beat Berwick Rangers. At the other end, Queen's Park are eight points adrift after a 5-2 Hampden humbling by Annan Athletic.
