Barnet 1-0 Tamworth
Luisma Villa made Conference Premier strugglers Tamworth pay the price for a missed penalty as he fired play-off chasing Barnet to a late win.
Lambs striker Justin Richards was fouled in the penalty area by Andy Yiadom but wasted his spot-kick as Nick Jupp saved comfortably.
Tamworth's Richie Baker poked wide and Keanu Marsh-Brown saw an effort parried by Cameron Belford at the other end.
Villa converted Marsh-Brown's late cross to earn victory for the Bees.
Tamworth's third Conference Premier game without a win leaves them fourth from bottom, a point from safety, although with three games in hand on 20th-placed Chester.
