Livingston 5-0 Dumbarton
Winless Dumbarton suffered more misery as they were emphatically beaten at Livingston.
Livi, who had lost their last two league games, went ahead in the ninth minute through Marc McNulty's low volley from 12 yards.
Craig Barr headed home Anthony Andreu's left-wing cross from close range to double the lead three minutes later.
Chris Turner wasted a glorious chance to get Dumbarton back in the game in the 18th minute, firing his penalty wide following Barr's foul on Bryan Prunty.
McNulty scored his second nine minutes before the interval with a left-footed volley from inside the box.
Substitute Callum Booth added the fourth with a neat finish from six yards and Keaghan Jacobs curled in a free-kick from the edge of the area with 13 minutes left to complete the rout.
