Slinfold captain Guy Thorne wants his side to rediscover their hunger to mount another promotion push next season.
Their hopes of making the top two were ended on Saturday as Crawley beat them by 99 runs to take runners-up spot themselves.
Slinfold had originally made a thunderous start to the season, winning their first six games, but have struggled in the second half of the campaign.
Saturday’s defeat means they cannot now finish in the top two with Crawley promoted alongside champions Mayfield.
Thorne said:“Our promotion hopes were over on Saturday, with another disappointing performance in the field preventing us from having an opportunity to secure a win and take things to the final day of the season.
“It’s been a very frustrating second half of the season, and it feels a little strange as we’ve got the same squad of players that won six of our first seven games.
“We seem to have lost our cutting edge and are low on confidence – but a third-place finish would still be a very creditable season. It still feels like a huge opportunity missed, but we’ll need to come back stronger and hungrier next year and try to mount a serious bid.”
A number of dropped chances of Crawley’s top scorers came back to haunt Slinfold after they won the toss and inserted their hosts.
Paul Clifford made 34 and captain Harry Chaudhary hit 73 in their total of 178 and Thorne said: “For the second week running it was another tale of missed chances with more catches going down, and for the second week running it cost the match again.
“We dropped their opener who went on to bat patiently for 30 overs, and we also dropped their skipper twice in three balls in the teens, and he went on to score 70-odd in a low scoring game.”
Harrison Webb took 5-42 and Sean Overton 2-11, before Slinfold then replied with 79.
None of the top six made double figures as they fell to 14-6 with Chaudhary (4-37) doing the damage. Steve Haines (25) and Thorne (27) then added some late runs to give the scoreline some respectability.
