Morton missed the chance to move up to second in Scottish League One as James Lister's goal handed Airdrie a 1-0 victory. Airdrie had two excellent chances to open the scoring in the opening 24 minutes, Morton's unnamed trialist producing saves to deny Ben Richards-Everton and Nathan Blockley. The goalkeeper was unable to keep out Lister's effort two minutes after half-time, though, the striker converting Blockley's cross from close range to notch his fifth goal of the season. The hosts almost salvaged a point in the 62nd minute but Declan McManus' right-footed effort cannoned back off the crossbar. The victory extends Airdrie's unbeaten streak to five matches, moving them four points off the play-offs.
