Buckleboo progressed to the Eastern Eyre cricket A grade grand final with a nine-wicket success away to Cowell on Saturday.
The hosts were bowled out for 175 before Buckleboo powered to 1/177 in response.
Cowell opener Zac Crabb impressed with 54 runs, with support from Todd Schumann's 17.
With Cowell sitting at 6/83 the pairing of Crabb and Ethan Grigg, 31 runs, pushed them into triple figures.
The partnership of 44 would come to an end when Grigg was caught, while Judd Wykamp added 25 late runs for the hosts.
Shannan Larwood, Jack Lienert and Joey Lienert all led with two wickets apiece for Buckleboo.

They added 170 runs, with Fitzgerald not out on 106 and Larwood reaching 52.
Wykamp took the lone Cowell wicket.

Also helping to keep the scoreboard ticking over were Dylan Jenner with 29 runs, Pat Jenner's 28 and a further 20 from Ben Shannon.
Brodie Pearson bowled well to take 4/24.
Pearson was the standout with the bat as he made 31 runs, with opener Riley Haines adding 19 runs and Jamie Pearson 18.
The latter's dismissal left Darke Peak at 5/106 and the wickets tumbled as the visitors were all out only 22 runs later.
Zane Crettenden did the damage with 4/32.
