Blyth went down to Kirkley after a woeful batting display with home bowler Louis Mitchell taking six wickets.
The visitors lost the toss and made a disastrous start.
Openers Chandra Purma (3) and Darren Carr (0) were both quickly back in the pavilion as Mitchell struck early.
Craig Smith and Kevin Hudspith looked to settle the innings down, but the former was Mitchell’s third victim, bowled for ten.
After a 20-minute rain delay, Robbie Burns claimed the next wicket as Hudspith was caught by Jonathan Ball for ten.
Mitchell was back among the wickets shortly after as Andy Rowell (8) and Blyth skipper Mark Lawrence (6) both had their stumps removed. This after Lawrence had been dropped four times.
Joe Turnbull replaced Burns and had Ruan Kirkup trapped lbw for nought.
Cameron Walker and Peter Roberts stabilised the innings until the latter became Mitchell’s sixth wicket when he was bowled for 11.
David Ebdale was bowled by Alex Ball and Ruwan Silva was run out, both without scoring as Blyth were dismissed for 87. Walker remained 13 not out.
Kirkley’s wicket-takers were Mitchell 6-35, Burns 1-25, Turnbull 1-24 and A Ball 1-0.
In replay, Blyth’s Lawrence and Ebdale did their best to halt Kirkley’s charge towards the low target.
Ebdale took 3-53 from ten overs and Lawrence 3-2 from seven overs – including five maidens.
They took wickets regulary as only Craig Johnson (12) made any score in the top order.
But in two overs from Ebdale the game went Kirkley’s way as they struck 26 runs.
Home skipper Andrew Storey top scored with an unbeaten 22 as his side reached their target in 21 overs.
Jason Ritchie (13) and Richard Moon (11 no) were the only other two batsmen to reach double figures.
Kirkley 25 points
