The Borders and East Lothian Under-18 side recovered from disappointment last week to put Edinburgh to the sword with a blistering display of powerful running rugby.
They run out winners by 40-10 with three fine first half tries by Roddy Main, Cameron Hutchison and Ruairi Campbell. Scrum half Gary Munro converted all three. Edinburgh scored a try by Calum Harris to make it 21-5 at half time.
Edinburgh scored first in the second half through Ferguson Haig but that just stung the Borders into life again and further tries by Main, Finlay Scott and Hutchison, Munro converting two, sealed the win.
