Adam Nichol and Michael Thewlis featured in an unbroken seventh wicket partnership of 97 to guide Ashington seconds to victory against the odds at Langwell Crescent on Saturday.
The pair came together with the home side in a precarious looking situation of 73-6 as they chased 167 to win.
But they gradually chipped away at the target and swung the pendulum back in their favour.
Nichol finished unbeaten on 54, his first half century of the season, and Thewlis 39, the latter hitting the winning boundary as the pair clinched the win with six overs remaining.
As a result, the Colliers, the defending champions, consolidated their position at the top of the B1 division.
Youngster Matty Potts continued his good run of form as he hit 30 after Dave Newton had top scored for the visitors with 63.
Afterwards Ashington-born Nichol, who will be 20 next month, said: “My thoughts were to be positive, we couldn’t sit back and let the bowlers dominate and I still believed we could win the game.
“Tynedale bowler Dave Newton was swinging the ball quite a bit and the plan was to see the openers off.
“We played every ball on its merit, pushing for ones and twos and punishing any bad deliveries.”
Nichol, who is studying sports science with coaching at Northumbria University but who also doubles up as a part-time cricket coach for ‘Chance to Shine’ with the Northumberland Cricket Board as well as doing voluntary referee development work for the Northumberland Football Association, added: “One of the assets of our side is the strength in depth we have in the batting department and I thought that shone through.
“We were in a perilous position at one stage but to clinch victory just shows how strong we are. We have collected 18 points today I’m really pleased.”
Skipper Doug Potts added: “Conditions deteriorated as the second innings progressed and we just got the game finished before heavy rain came which would probably have led to abandonment.
“However, I have got to say that the match was played in a really good spirit.
“We are two games away from the half way mark in the season and for Saturday, Scott Dunn – who scored a century in the game against Newcastle City but who was unavailable last weekend – returns.
“It will be good to have him back as it will strengthen the batting even more.”
