Morton clinched the Development League West title with a 1-1 draw against closest challengers Ayr United at Cappielow on Monday night.
Jon Scullion scored after 14 minutes and, although Ryan Nisbet equalised from the penalty spot 13 minutes from time, the point was enough to secure the championship.
Andy Millen's side complete their fixtures against Airdrieonians - who won the Development League West last season - on Thursday but they are likely to be presented with the trophy at a first-team game during April.
Meanwhile, Stirling Albion, Raith Rovers and Forfar Athletic are all still in with a chance of winning the Development League East as the season nears a conclusion.
