CAWTHORNE secured the Championship title and now want to establish themselves in the ECB Premier League.
They are 16 points clear at the top with a game left, one year on from being relegated out of the top flight.
Captain Mike Jepps said: The objective was to get straight back up.
“Barring the two games we’ve lost, both at home, we’ve been confident all year that we would achieve it.
“It’s nice to have to done it with one game left when we’ve had so many rained off.
‘We were on for the treble at one point but to get the double then represent the county in the north T20 finals last week was great.
“It’s been a really good season.
“The lads have enjoyed it and we’ve gelled nicely.”
What is the objective for next season?
“The aim is not to be a yoyo club.
“When you look at the size of our club and compare it to Barnsley and others who have loads of depth and teams, we’re not a massive club.
“We probably need a few signings. But we will learn our lessons from last time, and take confidence from this year.”
Cawthorne defended 166 by skittling Barnsley Woolley Miners 2nd XI for 85.
Ryan Gibson took five wickets and Methushan Thilina three after Liam Wiles top-scored with 62.
Max Heseltine took five wickets for Barnsley.
“We were 114 for nine and up against it but we got to a competitive total.
“Ryan Gibson took his first ever five wicket haul and bowled really well.
“It was a comfortable win in the end.”
At the other end of the table, Darfield were relegated after losing their crucial game at Wath who secured safety.
Darfield were removed for 87 with Rob Barlow taking six for 11 and Alex Roebuck the other four wickets.
Wath won with four down in the 18th over.
They are 12 points clear of Darfield who cannot catch them after losing twice to them this season.
Houghton Main’s promotion ambitions suffered a blow as they lost by a wicket to Sheffield Collegiate 2nd XI.
