Cowdenbeath stretched their lead at the top of the Scottish Second Division to four points after beating Dumbarton.
Joseph Mbu headed Marc McKenzie's corner into the net to give the visitors a third-minute lead.
Lewis Coult almost nodded home a second on the half-hour mark, his effort slipping wide.
But McKenzie's long-range strike 17 minutes from the end made sure of victory.
