Chorley are just one game away from a final appearance against Bamber Bridge at the Reebok Stadium in the Lancashire FA Challenge Trophy.
It follows their 4-0 demolition of Blue Square Premier rivals Southport at Haig Avenue on Thursday.
The win was Chorley fifth in 13 days and was arguably their most impressive.
Following the initial set back of losing keeper Dean Porter midway through the second half, Chorley stood firm in the first half and were unlucky to go in at the break all square against a side that contained six regular Port first teamers.
Indeed the Chorley side saw more changes to the starting 11 when you comparing both sides line-ups to their previous fixture.
The second half performance through brought back memories of the opening games of the season as the rampant Magpies ripped Southport's defence apart at will.
Livewire Shelton Payne netted twice before the hosts were reduced to ten men, than further goals from Dale Whitham and a 30 yard last minute chip over the keeper from Nathan Fairhurst sealed the win before Southport lost another player to an early bath.
In the semi-final Chorley face AFC Fylde at the County Ground, Leyland, on Wednesday January 26th.
The prize for the winner being a trip to the Reebok Stadium to face Bamber Bride on Monday March 14th in the final.
