Spencer Cricket Club will be playing in the Premier Division of the Surrey Championship next year after a five-wicket win over Beddington confirmed their promotion.
Moreover, with two matches to play, Spencer need just seven more points from a possible 26 to claim the division title ahead of Ashstead and East Molesey.
Having won the toss, Spencer elected to bowl and Patrick Turk did the damage, taking 5-52 as Beddington were skittled for 134 off 40.2 overs.
In reply, Ritchie Bann (33) and Krishna Sivakumaran (33) provided the base for Spencer to reach their target in the 31st over.
Spencer host Old Whitgiftians on Saturday before the visit of Valley End for the season finale.
