Managerless Waverley tumbled to defeat in a Division A encounter after being hit by a last-minute goal.
After a goalless first half United drew first blood when Daniel Pattenden fired the visitors in front, but Waverley drew level when Darren Munro netted after Luke Cooper and Jason Inglis had done the spade work.
Waverley were then unfortunate not to go ahead. On gathering a Luke Cooper pass, Inglis beat Chirnside keeper Martin Todd with a fine shot, only to see his effort cannon off the post.
Connor Lough scored the winner two minutes from time to secure Chirnside’s second victory over the Hawick outfit in as many weeks.
Paul Brownlee resigned from his position as manager of Hawick Waverley FC back in October following a poor run of results. The position has yet to be filled.
