Morton beat Inverness CT 1-0 at the Caledonian Stadium to end a run of 10 games without a win and move up to sixth spot as Caley Thistle dropped to ninth in the table. Aidan Nesbitt scored the only goal of the game early in the second half.
In the night's other match, second-placed Raith Rovers drew 0-0 with Ayr United - who again had Davie White in interim charge - at Stark's Park.
