The two teams played three 30 minute halves in the heat, with boss Alan Knill running the rule over the fitness of his squad as they prepare for a trip to Grantham this Saturday.
The Stag's winner came in the second 30 minute period as they capitalised on a defensive error to bag the only goal.
Fans making the journey to Grantham are reminded it's an evening kick off of 7pm and the cost on the gate is £5 and £3. There's a train back at 21:39!!!
