Bamber Bridge suffered their third defeat of the season at high-flying Warrington Town.
The Wire’s victory courtesy of a goal just after half-time by ex-Chorley striker Ciaran Kilheeney means they now go back to the top of the NPL First Division North while Brig drop below midtable.
These two sides were pre-season favourites for the league title and opened the season with a 2-2 draw at the Sir Tom Finney stadium in the reverse fixture.
Neil Crowe’s men have been off the pace since then, though they came close to opening the scoring when Brett Ormerod headed over from close range.
In a lively opening, Warrington came close when Chris Gahgan had a shot blocked and then Lee Dovey had to make a save from his own defender to keep the game scoreless.
The pace of the opening 15 minutes was short-lived, and the rest of the first half passed with little event.
Sam Joel flicked a dangerous free-kick straight at Karl Wills, who had a nervous moment when he spilled a header in to the path of an offside Ormerod.
The decisive moment of the game came in the early stages of the second half.
Scott Metcalfe whipped in a curling free-kick from the right hand side, and it was glanced home by Kilheeney.
Ben Deegan had a chance to finish the game for the home side on the hour mark, poking just wide, though the better of the play was coming from the visitors.
In the end, Brig could not find an equaliser as Town took all three points.
Elsewhere, Lancaster’s match with Burscough and Kendal’s game at home with Farsely Celtic was postponed and Clitheroe drew 1-1 with Prescot Cables.
