Jed consolidated their advantage over nearest rivals Watsonians after winning the 86th Earlston tournament on Sunday.
The victory, only their second success in the Kings competition this season, atoned for their early exit at Kelso on Saturday, when they lost in the first round to Melrose, the eventual winners at Poynder Park.
Jed, meanwhile came through the first two rounds in the top half of the draw, cruising past Berwick and Duns without conceding a score. Duns had performed well in the opening round disposing of Lasswade 36-10.
In the first of the semi-finals, Jed overcame a feisty and skilful Selkirk side 26-17 to book their place in the final.
Watsonians also had an untroubled passage through the first two rounds and defused the Powerbomb threat 34-0 in the second semi-final.
Then, in the final, tries by twins Lewis and Gregor Young and one by Robert Hogg gave Jed a 21-0 lead. But, when Lewis Young was binned for a high tackle, Watsonians ran in two tries by Robbie Greenhaugh.
Jed, however, added a brace by Ross Combe, Watsonians only reply a try by Euan Miller, leaving the Riverside team title winners.
