Bedlington first XI went into the penultimate league game of the season knowing victory would take them to the brink of promotion.
Due to a clerical error, the campaign will go down to the final game and five points from the final game away to Newcastle City will guarantee the Hirst Head side promotion as runners-up to Percy Main.
Matty Tanney returned from injury on Saturday to replace Chris Pearson, who returned to second team duties, and in winning the toss, Darren Leason decided to bat first.
Chris Younger and Kev Harnett opened up and got off to a solid start until the former fell for 20 with the score on 34.
Dan Younger joined Harnett and the pair scored freely, adding 99 runs.
Harnett fell for an excellent 69 from 93 balls including three sixes and seven fours, and Craig Robinson followed in the same over without scoring.
Matty Tanney joined Dan Younger and steadily took the score to 198 before Tanney was out for 27.
Jonny Richards came and went quickly and Leason was next in.
Dan Younger became continually expansive and brought up a well deserved century to finish with 102 from 110 balls. His innings included two sixes and 14 fours.
Leason ended 24 not out and Nicky Carr five not out with a final total of 270-6.
Morpeth started the reply sloppily and found it difficult to turn the tide from the sluggish start.
Chris Younger removed both openers and finished with 2-19 from eight overs.
Matty Tanney and Nicky Carr bowled economically during the middle overs but could not find the breakthrough.
Rick Jones (28) and John Turnbull with a superb 93 held the home side up until Paul Rutherford came on to wrap up the innings in typical fashion.
The evergreen Rutherford claimed 6-33 from his ten overs and was well supported by Dan Younger with 2-16.
Morpeth were eventually bowled out for 156, giving Bedlington a win by 114 runs.
Bedlington 20 points
Morpeth 5 points
On Saturday, Dan Younger and Jonny Richards are unavailable with Connor Leason and Chris Pearson stepping up for the crunch game versus Newcastle City.
Bedlington seconds were celebrating promotion on Saturday in their first season in the NTSL, after an emphatic ten wickets win at Morpeth, bowling a very young inexperienced home side out for a paltry 18 runs.
Youngster Josh Watson again showed his talent with incredible figures of four overs, three maidens, six wickets for one run, Hutchison, Taylor and Purvis sharing the other wickets.
Shepherd and Leason hurried the Terriers to victory in 2.3 overs.
A club spokesperson said: “To gain promotion straight away is a credit to the players and they should be proud of their achievements, but a lot of hard work and commitment lies ahead for season 2015.”
This weekend the seconds are at home to Consett and it is hoped there will be a happy club house if the firsts can also gain promotion.
