Tamworth sub Kyle Patterson hit a last-minute winner as two late goals saw the Lambs secure a 2-1 win at home to Blue Square Bet Premier strugglers Hayes.
The visitors took the lead when Francino Francis was penalised for a foul on Pierre Joseph-Dubois and Louis Soares made no mistake from the spot.
But on-loan Kieron St Aimie levelled after Hayes failed to clear a corner.
And the home side then stole the points when Patterson tucked home a Danny Thomas cross from six yards.
On-loan Kettering front man St Aimie started the revival on 83 minutes with his fourth goal in three games before Patterson completed the turnaround - just 15 minutes after coming on.
