Archibald Campbell struck his 12th goal of the season as Morton beat Falkirk to stay top of the Scottish First Division.
Morton grabbed the lead with the first real chance after 30 minutes and it was Campbell who did the damage when he coolly swept home from close range.
He should have doubled Ton's advantage moments later but missed the target when well placed.
Falkirk's first chance of note came after 40 minutes when David Weatherston blasted over.
The Greenock side doubled their lead a minute before the break after Michael Tidser's cross found Peter MacDonald and he planted his header into the bottom corner.
They almost added a third after 74 minutes, but David O'Brien's audacious lob cleared the crossbar.
