Hibernian have been shocked by Kelty Hearts as the Premiership side suffer defeat to the League One club in the group stages of the Premier Sports Cup.
A Callum Flatmann strike in the second-half was enough to give Kelty all three points on Saturday afternoon.
Last season’s defeated finalists Aberdeen made it two wins from two this campaign with a 4-0 win over East Kilbride in South Lanarkshire.
Goals from Devlin, McGrath, Clarkson and Morris handed Jimmy Thelin his second win as he keeps up a 100% record since joining the Dons from Elfsborg in the summer.
Elsewhere Motherwell beat Clyde 3-1, St Johnstone secured all three points with a 2-0 victory over Greenock Morton in Perth and Ross County beat Raith Rovers 2-1.
All Scottish league teams other than the five top-flight sides in Europe are taking part in the group stage of the competition on the road to Hampden with the first trophy of the season on the line.
Celtic, Rangers, Hearts, Kilmarnock and St Mirren will all enter the tournament in the second round.
