Livingston emerged victorious in a battle with Aberdeen that saw 14 yellow cards, a red card, some frantic last ditch defending from the hosts and a contest that at times resembled more of a schoolyard fight than a game of football.
The Lions opened the scoring on eight minutes when Ayo Obileye turned a Bruce Anderson strike beyond Gary Woods before a wonderful finish from Alan Forrest just after the break doubled their lead.
At times, the hosts were cutting Aberdeen apart every time they got over the halfway line and Jason Holt could have all but wrapped the game up had his strike not bounced off the post.
