Ross Gray's first-half strike was enough to earn Berwick a 1-0 win at East Stirling.
The home side had started brightly, with Michael Herd firing a shot straight at Ian McCaldon and Kevin Turner volleying wide from close range.
But it was the visitors who opened the scoring in the 21st minute when Lee Currie's near-post corner was converted from six yards by Gray.
East Stirling goalkeeper Grant Hay had to be at his best to keep out a Currie free-kick, while at the other end Turner came close again.
The home side enjoyed the better of the second-half chances, with McCaldon denying Nathan Shepherd and Jordan Holt heading wide.
But the closest they came to a leveller was in stoppage time as the lively Turner saw a 12-yard strike come back off a post.
