Guisborough created history on Saturday when they became the first club in the history of the league to win the top division for four consecutive seasons on two occasions.
They celebrated swiftly at Brinkburn Road gaining the necessary four points before the halfway stage.
Saul Clifford struck five boundaries in 56 and Chris Murray ended unbeaten on 50 as the magical total of 175 was achieved. The 50 overs produced 185-7 but by then it was academic.
Andrew Russell bowled unchanged for 25 overs, returning 4-73, and David Eckels then batted throughout for an unbeaten 83 as Darlington RA responded with 136-7.
Incredibly, David Towse bowled 15 overs for 13 runs and Paul Goodchild returned 3-35 from his 12 overs but it hardly mattered as Guisborough were crowned champions once their innings reached 175.
Rain - not for the first time this season - was the winner at Park Drive where runners-up Bishop Auckland were struggling on 74-6 replying to the Hartlepool total of 132.
Richard Hawthorne was still there but Ashley Day and Ian Palmer had shared six wickets to put Pool into a strong position.
When they made first use of the wicket the home side also found the going difficult and 43.1 overs produced a meagre total which would have been a good deal less but for a late unbeaten 39 by Andy Carter.
The weather also closed in at other grounds. At Acklam Park, Middlesbrough were 130 for two from only 24.1 overs when the match had to be abandoned.
Brenton Parchment struck three sixes and five boundaries out of 44 and Darren Birkett had one six and seven fours in an unbeaten 66. Batting first, Darlington were all out for 194 with three balls remaining.
Great Ayton had lost just one wicket with 83 runs on the board at Richmondshire. Darren Hickey was undefeated on 30 and Andrew Doyle contributed 32 as Ayton chased the Richmond total of 199-8.
Mark Layfield top-scored with 57 and his brother Clive added 33 while for Great Ayton, Gunnaratne claimed five for 57.
Northallerton end in third following their visit to Redcar where Jonathan Barnes just failed to reach 100 wickets for the season.
He needed three but managed only two as the Seasiders innings ended prematurely on 129-3 with 20 overs remaining.
Although it would be little consolation to him, Barnes was in top form with the bat and his 74 not out, together with 61 from Jerry Hall and 48 by Doug Mulholland enabled Northallerton to post the formidable total of 242-4.
Saltburn signed off with a six-wicket victory at Marske who finish second from the basement ahead of Blackhall.
