Jemson's brace helps keep; Shrewsbury 2 Mansfield 1 Shrews on winning track.
Kevin Ratcliffe's youngsters furnished further evidence of their growing maturity but the two-goal hero of Shrewsbury's third win on the bounce was very much at the opposite end of the age scale - veteran marksman Nigel Jemson.
Steve Jagielka had already fired against the Mansfield bar when Jemson opened his account in the fifth minute.
The goal was set in motion by goalkeeper Paul Edwards' controlled clearance to release Karl Murray on a right wing run.
The teenage midfielder's cross fell perfectly for Shrewsbury's acting captain to sweep a delightful volley past Bobby Mimms from the edge of the box.
A reshuffled defence, reinforced by a highly-efficient offside trap, coped admirably with the best Mansfield could offer, and just before the half hour only a glaring miss by Jagielka prevented Shrewsbury doubling their lead.
Luke Rodger's measured centre from the left reached his midfield colleague barely six yards out but a disappointing header went straight into the keeper's hands.
Shrewsbury's early sparkle gradually vanished on a pitch which became progressively heavier, but the points looks safe enough when seven minutes from time substitute Chris Freestone helped set up Jemson for his second goal.
But the drama was not yet over. Edwards promptly scuffed a clearance straight to the feet of Lee Williams, and was still charging back to his unprotected goal as the Stags' midfielder clipped the ball over his head from fully 30 yards.
