Edgehill hit back 10 minute before half-time with Danny Collins poking home after good work from Paul Watson.

There was still time for Shaw to hit the post for Edgehill and Luke Delve to hit the bar for the hosts.

Filey made a great start to the second half, Cam Dobson heading in after a fine run and cross from defender Gary Wardell.
Another slip in the Town defence then allowed Neil Hart to lob the Filey keeper from 35 yards to make it 2-2. The visitors soon regained their lead though, Wardell scoring from the penalty spot after Ricky Tomlinson had been fouled.
