Ten-man Boston suffer derby loss
The Poachers suffered a disappointing derby defeat to leave them still uncomfortably near the wrong end of the table.
Scott Coupland put Deeping ahead after 35 minutes with his 100th goal for the club.
Two further goals late on completed the victory - with Boston's frustration compounded as Craig Parker was sent off.
