Alfreton No 2 were also still in contention if they could upset their No 1 team with a wide margin win but that notion was soon quashed as Andrew Beardsley and Paul Pilsworth took the opening two frames.
Ralph Edgson took the next and then Kevin Rowland, on the black, set up what could have been a pending whitewash but John Smith and Andrew Haggarty restored some pride for the defeated.
So the 4-1 win for Alfreton No 1 left Edgefold No 1 needing the same scoreline to take the league championship trophy for the second time in three seasons but it didn't start well as Matlock Golf Club's Ian McKay took the opening frame.
Neil Parkinson emerged from a hard fought tactical frame to equalise, however, and despite Paul Roe's 36 break in the next, Duncan Harwood produced a masterful performance to take a red, colour and all the remaining balls in several visits to take the frame on the black.
Andy Russell then made it 3-1 with an 81-65 verdict and then took the deciding black in the doubles from right under the cushion, aptly helping to win one of the tightest league battles of all time for his by a final frame score of 45-44.
Bolehill No 1 finished third after an inactive final week and the No 2 team from that neck of the woods probably wished they had been too as they fell 5-0 to Belper Strutt Club.
Steve Bullock and Mark Newby each won on the black to get the visitors rolling en route to their ninth win in ten games in all competitions and their second successive whitewash.
