Gateshead 1-2 Tamworth
Gateshead keeper Jak Alnwick was at fault for both goals as Tamworth beat their Blue Square Bet Premier rivals.
Francino Francis put the Lambs ahead from two yards after Alnwick, on loan from Newcastle, dropped a corner.
The Heed had Chris Carruthers sent off for a foul on Danny Mills but Alnwick saved Kieron St Aimie's penalty.
Nathan Fisher swivelled and finished to make it 1-1 but Alnwick dropped another corner in the last minute and Kyle Patterson was the Lambs' hero.
