Brigg began brightly with Alfie Usher and Dayle Hutson forcing Jordan Quibell into smart stops before Josh Batty came close with a great effort.
Bottesford Town were ahead briefly when Harry Webster found the net with a 20-yard shot. However, Brigg soon equalized through Batty who fired home after good build-up play involving Conner Harman and Hutson.
Further opportunities arose at both ends of the pitch up to the half time break, but the score remained at one goal each until then.
Brigg picked up where they left off in the second half taking the lead on 52 minutes when Chaz Fisher headed in Martin Pembleton’s corner.
The Poachers responded with a shot from Declan Bacon that Tom Collins tipped over at full stretch.
Bottesford’s Luke Ayris equalized forcing the ball into the back of the net from close range following a corner kick.
Afterwards, neither side could find a winner so a penalty shootout was required. The Zebras won it 3-0 with James Petronzio, Jack Richardson and Usher all converting their spot kicks and Collins saving a couple.
The Zebras will host Boston Town in the semi-finals.
