Harry Limb and Fraser Bayliss scored first half goals to seal an impressive league double against Sleaford Town.
It was a derby defeat that all but snuffed out the Greens’ last lingering play-off hopes.
By contrast, the Poachers were cock-a-hoop as they got back to winning ways and moved level on points with 9th-placed Deeping Rangers in the United Counties League Premier North.
Harry Limb opened the scoring after just 7 minutes as he headed home a Lee Beeson corner, ending a goal drought that stretched back to August.

Boston Town continued to dominate the first half and Fraser Bayliss swept home a second after 34 minutes.
The home side improved after the break but Martyn Bunce’s side deservedly hung on to a clean sheet, remarkably their 7th in their last 9 league games.
The Poachers boss told Tom Carter from Lincolnshire Non-League Radio he was over the moon to see Harry Limb score.
