Boston Rugby Club were left rueing a handful of errors which saw Lincoln end their Midlands 3 East (North) winning run 38-18.
Forced mistaked and two interception tries played their part in this match at the Boardsides.
Blue and Whites coach Willem Jonker reshuffled his pack due to the absence of a number of players, bringing Anthony Buckberry and Will Scupham into the front row and moving Mathew Dean into the backs.
Tom Andrews partnered Jake Brooks in the centre and the team welcomed back Marc Miles, Ross Noble and Travis Cross on the bench.
The visitors scored first with a well-worked catch-and-drive to move 7-0 ahead.
Playing against the wind, Boston were struggling to mount any serious attacks - and when they did get into the visitors’ 22 they conceded penalties in the loose.
With the last play of the half, Boston lost their own scrum ball and Lincoln moved 12-0 in front.
A third try moved Lincoln 17-0 ahead before a Tom Andrews penalty brought Boston’s first points.
Lincoln added an interception try to move 24-3 ahead before Boston then produced a 15-minute purple patch to score two quick tries.
A quickly-taken tap penalty by Scupham was stopped short of the line, only for Dean to drive over.
Then came the best try of the match.
Slick handling in the backs saw fly half Dan Halliday produce a deft back of the hand off load to create space for Andrews to score in the corner.
Hopes of a comeback were quickly snuffed out as an interception try moved Lincoln 13-31 ahead.
Perry Cumber reduced the deficit to 18-31 before Boston conceded with the last play of the match.
The result means the Blue and Whites drop a place to seventh.
Boston return to action on December 6 at Mellish (KO 2.15pm).
