The only goal came in the first half of a game that was dominated for long periods by the home side.
In the second half, O's came close several times, none more so than with a header that was tipped over the bar and a mazy run from sub Lewis Powell that ended with the striker poking just wide of the far post.
Radstock hit the woodwork late on too but in the end, that first half goal was all that separated the two sides.
