Neither can be caught by sixth-placed Eastbourne United, so will take their place in the end-of-season knockouts alongside Guernsey and whichever of Haywards Heath or Steyning don’t win the title.
An early goal by Callum Edwards and late strikes by Ross Barclay and Trevor McCreadie won it for Peacehaven – with Jordan Maguire-Drew and Charlie Martin scoring to put YM 2-1 up at one point.
