Denny Johnstone scored a brace as Morton beat Queen of the South to move up to fourth in the Championship.
The hosts had a number of chances to take the lead in the first-half but could not find a way past visiting goalkeeper Robbie Thomson.
The Ton finally made the breakthrough after the break when Johnstone found the top corner from 20 yards.
And Johnstone doubled his side's advantage when he got on the end of Ross Forbes' corner to nod home.
