St Lawrence were relegated after losing 5-1 at St Paul's after one season in the island's top flight.
Craig Russell, Jack Cannon, Craig Leitch, Steve Wilkinson, and Bruno da Silva all scored for St Paul's.
St Paul's are eight points off Scottish with a game in hand and must win all their remaining games and hope the Scots fail to win more than one of their final three if they are to win the title.
St Brelade went four points clear of the relegation zone with a game in hand after a 1-1 draw with western rivals St Peter.
Dan Romeril scored for St Brelade, with Chris Conning on target for St Peter.
