Parley's five-wicket defeat by Sway has kept the promotion door ajar for Fareham & Crofton, who could snatch an unlikely second place if they score a big win at St Cross Symondians III.

Lymington lurched closer to relegation with a four-wicket defeat by Old Basing. They looked set for the drop alongside already demoted Andover II.
