Steven Saunders' last-gasp equaliser secured a 1-1 draw for Dumbarton and denied Livingston their first win in five Ladbrokes Championship games.Scott Pittman's first-half goal looked to have earned Livi a much-needed win but in-form Dumbarton, who had won their last three in all competitions, levelled the game with a minute left.Livi almost opened the scoring after just two minutes through Jordyn Sheerin but the hosts did break the deadlock after a quarter of an hour.Good work from Jordan White and Sheerin teed up Pittman, who tapped home his second goal of the season.Sheerin headed a good chance wide for Livingston while Kevin Cawley's header flew narrowly over the bar in a rare first-half Dumbarton attack.Despite an improved showing after the restart from the visitors, chances remained hard to come with Frazer Wright forcing Marc McCallum into an easy save.However, Saunders slammed home a rebound after Mark Docherty's corner hit the post to seal a share of the spoils in West Lothian.
