Bryan Prunty's second-half goal was enough to give promotion chasing Dumbarton victory against relegation-threatened Albion Rovers.
Rovers' Jordan Halsman had an effort parried by goalkeeper Stephen Grindlay and Daniel McKay's follow-up was blocked by Alan Lithgow.
Prunty broke the deadlock on 61 mintues when he collected Agnew's pass and finished from 12 yards.
Keeper Chris Fahey denied Prunty a second when he tipped a shot around the post.
