Akhtar and Majeed claim four wickets apiece
Barnack claimed the first part of a potential Rutland League double on Monday with victory in the final of the John Wilcox Trophy.
The Division One table-toppers stormed to an eight-wicket win over Wisbech who were forced to a field a depleted team due to a clash of fixtures.
Four wickets apiece for Ajaz Akhtar and Arshan Majeed laid the foundations for the success as Wisbech were bowled out for 71.
Barnack had won the toss and elected to put their visitors into bat with Muhammad Yaseen claiming an early breakthrough.
Yaseen had opener Jon Garner caught off the second bowl of the second over to leave Wisbech on 5-1.
Dom Stannard (19) and Sam Rippington briefly steadied the ship before Akhtar opened his account for the afternoon by having the latter caught with Wisbech on 20-2.
Jason Esser lasted just three balls before he also fell to Akhtar with Matt Esser following nine runs later after being trapped leg before by Yaseen who finished his seven overs with a tidy 2-14.
Dan Oldfield defied the Barnack attack for 20 balls without troubling the scorers until he was caught by Shahid Muhammed off Akhtar.
Top scorer Stannard then followed after becoming Majeed's first victim, courtesy of a Kasim Ikhlaq catch, to leave Wisbech on 38-6.
Tom Jupp was bowled first ball by Akhtar who completed his 10 overs by returning fine figures of 4-21.
Majeed and Ikhlaq again joined forces to dismiss Lyndon Mallett which left Wisbech reeling on 48-8.
Lewis Jackson (12no) and Joe Dunning (13) then enjoyed Wisbech's best partnership of the day as they put on 23 runs for the eighth wicket.
However, Majeed had Dunning caught by Abdul Shafiq with the score on 71 and then three balls later trapped last man George Gowler leg before to wrap up the Wisbech innings. Majeed finished with 4-16 from 6.5 overs.
Barnack also struggled for runs early in their reply as Ikhlaq fell for four courtesy of Matt Esser's catch from Rippington's bowling.
Akhtar was then caught by Oldfield off Gowler to leave Barnack on 13-2, but this brought Yasir Mirza and Asim Butt to the crease to take control of proceedings.
Butt blasted seven fours in an unbeaten 38 off just 36 deliveries while Mirza was 20 not out at the close as Barnack breezed home in 13 overs to move closer to a memorable league and cup double.
With the entire Rutland League programme washed out on Sunday, Barnack - who are without a fixture this weekend - currently hold a 13-point advantage over second-placed Bourne who have played a game more.
Third-placed Ketton Sports are 30 points adrift having played the same amount of games. Bourne visit Kings Keys on Sunday while Sports travel to reigning champions Wisbech.
