a
The Zebras had chances but reached half-time with a 0-0 stalemate.
However, within three minutes of the restart Dayle Southwell applied enough pressure on the keeper to force a punch away, landing at the feet of Hutson who passed the ball home.
Adam Drury almost doubled the lead near the end but saw his finish come back off a post.
Joint Brigg boss Steve McCarron said: “It was a good performance.
“We had to grind out a result.
“We seem to be good on artificial surfaces.
"But, hat's off today, we won on a grass pitch and it’s nice to tick that box and get it over and done with.
“That is five clean sheets in a row which we are delighted with. If you keep clean sheets you don't lose games of football.
“Dayle finished his goal really well – that's three goals in three games, which is great for us. We are top of the league so we are happy.”
