There was a Jaidka Cup thriller at March last Wednesday as their group game against derby rivals Wisbech ended with the scores level on 135 runs apiece.
But Wisbech Wildcats have been declared winners because they lost fewer wickets.
March Crows batted first and totalled 135-9 from their 20 overs and Wisbech recovered from 52-4 after seven overs to finish on 135-8.
Paul Edgeller was the Wisbech hero, finishing unbeaten on 45 as his side took 14 off the final over to sneak the win.
If Wisbech win their final Zone D group game at home to Ramsey tonight they will qualify for the semi-finals.
Previous Cambs Tucker League Division One leaders Wisbech were beaten for the first time this summer by newly-promoted Eaton Socon by 68 runs.
Wisbech did reach 200 for the fourth match in a row, but they got no further and slipped to fourth in the table.
Eaton Socon posted 268-5 in their 50 overs (B. Apted 2-36, P. Edgeller 2-52). Wisbech began well with Danny Haynes (64) and Josh Bowers (39) in reply, but Ben Gowling struck with 5-29 as Gary Freear hit 23.
A terrific knock of 96 from Tommy Howgego helped steer March to a four-wicket victory at Newborough in Tucker League Division 2.
The left-handed opener’s highest first team score helped secure maximum points and keep the team in second place.
Newborough 185 all out (Anthony Palmer 3-36, James Harradine 3-30, Toby Nulty 2-30), March 1st XI 186-6 (Tommy Howgego 96, Toby Nulty 34, Nathan Oliver 19no).
The 2nd XI chalked up back-to-back wins from the two opening games in CCA Senior League Division 2, against Hardwick at The Avenue.
Veteran batsmen John Gilson and Steve Hinson were the backbone of the batting, while teenager Adam Conyard and Sam Mason shared five wickets in the narrow 13-run victory.
March 2nd 189-5 (Gilson 46, Hinson 41, Rob Conyard 27, Steve Coe 21 no), Hardwick 176 all out (Adam Conyard 3-26, Sam Mason 2-20), James Fountain 2-26, Sam Clarke 2-38).
For the second week running March 3rds came up against a much better side and slipped to a heavy 116-run defeat at Terrington St Clement in CCA Junior League Division 2N.
Terrington 225-5 (Charlie Revell 2-37), March 3rd 109 all out (Ross Shepherd 22, Ioan Foreman 21).
