Match ends, Morton 0, Livingston 1.
Nicky Cadden's wonder-strike brought in-form Livingston victory against promotion play-off rivals Morton.
The winger found the top left corner of the net from 25 yards for his first goal of the season.
Scott Pitman had the chance to extend Livi's lead almost immediately, but was denied by Morton goalkeeper Derek Gaston.
The hosts did hit the foot of the post through Mark Russell effort in the first half.
Livingston have now further consolidated their second place in the Championship, now eight points behind leaders St Mirren and eight ahead of third-placed Morton.
David Hopkin's men have won five of their last six games.
Visiting striker Ryan Hardie was almost gifted a goal in the first few minutes when Gaston spilled a cross, but he recovered well to divert Hardie's attempt wide.
Pitman tested Gaston again before Morton debutant worked hard to set up Russell for his low effort off the far post from the edge of the box.
Mikey Doyle was next to threaten for the Greenock men and Livi goalkeeper Neil Alexander was equal to the shot.
There were only two minutes on the clock in the second half when Cadden's impressive strike sailed past Gaston, and further efforts later clearly showed that had given him some extra confidence.
If Pitman's side-footed shot a couple of minutes later had been a bit harder, Livingston might have had a healthier lead, and Hardie kept Gaston on his toes with another low effort too.
Morton manager Jim Duffy: "It was a very difficult match and we knew it would be. They are a terrific side and they work hard and make it difficult for you to create.
"The one chance that came their way and Cadden scores a fantastic goal. I didn't think we were poor. I have no complaints about the attitude or work ethic of my players."
Livingston manager David Hopkin: "At half-time I had a wee go at a few of my players and asked for more. We score a wonder-strike and sometimes that's the difference.
"Young Nicky's come into the team the last few weeks and I've asked him to do more - that goal was worthy of winning any game and we defended magnificently the rest of the game."
