Livingston 1-3 Dumbarton
Dumbarton recovered from the loss of an early goal to beat Scottish Championship rivals Livingston at Almondvale.
Marc McNulty fired home to give Livi the lead but Mitchel Megginson's strike levelled the match before half-time.
The Sons won a penalty when Paul McGinn fouled Connor McDonald in the box early in the second half and Chris Turner converted.
And Bryan Prunty fired home Dumbarton's third.
