A solitary George Barber goal was enough to give the Division 6 leaders a 1-0 semi-final victory over Division 5 top dogs Pelham Arms in the Adelaide Cup.
Their reward is a showdown against Fort Cumberland, who sit second in Division Five, at Westleigh Park on Sunday, May 14.
The win came a week after Saturn had thumped White Horse Reserves 7-3 at Cams Alders to lift the Portsmouth & District FA Sunday Plate silverware.
And four points from their remaining three league fixtures will see them crowned champions.
