The Silkmen’s number ten flicked the ball with his back to the goal in the box which found its way past James Pradic despite his best efforts.
The Brig attempted to clear the ball from the box multiple times, but it fell to Rooney who capitalised in the 79th minute to put the home side 2-1 up.
The inform Kane Drummond opened the scoring in the 11th minute after a long ball from Drew Baker fell into the forward’s path.

Brandon Lee passed the ball down the line to Neil Kengni who played a through ball to Drummond in a threatening position.

His effort ended up hitting the side netting and going out for a goal kick.

Bamber Bridge appealed for a penalty in the 29th minute after Scarborough went down in the box, but he was given a yellow card for diving.
