Raith Rovers remain in second place in Division TWo after a narrow victory despite dominating throughout.
The goal came in the 27th minute when a 20-yard shot from Robert Sloan took a deflection on its way into the net.
Peterhead had a couple of chances early on with Dean Cowie having a shot saved before Callum MacDonald headed over.
Rovers were on top thereafter and it took a great save from Mical Kula to deny Steven Hislop as the visitors pressed for more goals.
