Chib Chilaka made his debut for The Gingerbreads as Paul Rawden made 4 changes to Saturday's starting line up.
Ryan Hall had the first speculative chance for The Gingerbreads but his shot from outside the box went wide of the post.
Matlocks Crouz had a shot cleared off the line, after the ball had come off the post.
Debutant Chib opened the scoring when he headed home from a corner. The power in the header was enough to beat the Matlock keeper.
Matlock almost equalised with a header from a corner at the end of the first half.
11 minutes into the second half Ryan Hall doubled The Gingerbreads lead. He broke free to get into a 1 on 1 with the Matlock keeper, and calmly slotted to the right hand corner of the next.
On the hour Matlocks Crouz hit the crossbar from a free kick. Crouz brought a great save from Tom Nicholson from another free kick. Matlock header a corner against the bar.
Matlock got a huge slick of luck when Marshalls shot deflected off James Berrett to nestle in the net and to make it a nervy final 3 minutes.
Late, late on in added time, the league leaders levelled with the last kick off the match. A free kick was whipped into the box which evaded everyone, including the Matlock keeper who had come up. Luke Hindsley managed to get a toe on the ball to avert the ball from any Grantham player and it went in.
