After the previous season's disappointments, Dumbarton were having similar problems in the league until a run of five victories at the end of the campaign improved the team's position to finish in a creditable 12th place with 34 points, 21 behind champions St Johnstone.

The League Cup was to prove the bright spot of the season, and after 3 wins and a draw from their sectional ties, and a subsequent play off win over Cowdenbeath, Dumbarton were to lose a close quarter final encounter against Rangers, the highlight being a 1-1 draw at Ibrox.
