Livingston moved a step closer to the play-offs with a comfortable 2-0 victory against already-relegated Airdrie.
Craig Barr's first-half goal was added to by a late Jesus Garcia Tena free-kick as the visitors won their first game in five,
Richie Burke's side went ahead in the 25th minute as Jordan Morton's corner picked out Barr on the edge of the six-yard box and the defender headed in his fourth goal of the season.
Livingston were awarded a penalty with 17 minutes left as Ricki Lamie brought down Kyle Lander in the area but Iain Russell's spot-kick was saved down to his right by Kenny Arthur.
But the penalty miss failed to lift Airdrie, who were aiming to end a seven-game losing streak and six minutes later the game was put to bed.
Grant Drummond fouled Kyle Lander 25 yards from goal and Garcia Tena arrowed his free-kick into the top corner to keep Livingston in third.
