Arbroath’s fate is still in their own hands after they beat Dumbarton.
The Gayfielders came out fighting, with Ian Nimmo and Mitch Megginson looking dangerous in the box.
Early on, Megginson burst through the defence, passing three Sons defenders, but his finishing let him down.
Robbie Ross also looked hungry and Dumbarton’s keeper Michael White did well when he denied the striker his chance.
But it was Jamie Redman who broke the deadlock, on 38 minutes, finding the corner of the net from just outside the 18-yard line.
Arbroath cemented the victory when, four minutes after the break, Megginson took advantage of poor home defending of a corner and slotted the ball away from a tight angle.
Jim Weir said of the team spirit that had given Arbroath a chance, “Our battling qualities were there for everyone to see.”
