Penryn Athletic Reserves beat local rivals Falmouth Town Reserves 2-3 at Bickland Park on Saturday in the Jolly's Combination League.
Matt Mcilroy put Penryn a goal up before Dan Richardson equalised for the home side.
But a brace from former Falmouth player Bobby Bryant gave Penryn a two goal lead.
And despite pulling one back thanks to a second Dan Richardson goal from a penalty rebound, Penryn were able to hold on for all three points.
Elsewhere Paul Murray's Wendron side continued their good run of form with a convincing 3-0 win over Falmouth Athletic.
The victory moves Wendron into seventh position in the table, and inches them ever close to Murray's goal of a top six finish this season.
