SHOBROOKE Park lost by 71 runs to visiting Plymstock to tumble into the B Division for next season.
Plymstock knew they were safe going into the game, but Shobrooke had to win if they were going to stand any chance of overhauling Braunton and staying up.
As Braunton beat Paignton by three wickets, the result was academic anyway and Shobrooke were relegated after a two-year stay.
Plymstock amassed 176 for six in 50 overs – Dan Robotham top-scoring with 44. Justin Dollow (3-40) was the leading wicket taker.
Only Eric Parmakellis (32) showed much stickability as Shobrooke were all out for 105 in reply.
Richard Pyle hit three successive fours then got out to Hallam Kerton, who turned the game with three quick wickets on his way to four for 13.
