Chorley had Lewis Guy’s late goal to thank for their second win in a week, having been a goal down against ten men Worcester City.
Former Doncaster Rovers forward Guy struck a winner two minutes from time to seal a vital three points for the Magpies.
Daniel Nti opened the scoring for the hosts in the 35th minute.
The visitors were level on the stroke of half-time, defender Clayton Donaldson inadvertently heading past how own goalkeeper.
Darren Stephenson scored his second in as many games to give Chorley the lead before Nti drew the sides level in the 76th minute with a well struck free-kick.
With time running out, Guy was introduced and within a minute of coming on, the pacy forward sealed the points with a close range finish.
The Magpies now sit 10th in the Vanarama National League North table.
On a warm afternoon at Aggborough, the home of Kidderminster Harriers, Chorley took to the field after receiving their first three points of the season against FC United on Tuesday.
The opening stages of the game were a cagey affair.
Neither side was able to create a clear cut chance, with set pieces being the Magpies best option.
Adam Dodd attempted an effort from long range but saw his strike go narrowly over Nathan Vaughan’s goal.
A Dale Whitham free kick found the head of Adam Roscoe but he could only find the roof of the net.
Worcester had been restricted to long range efforts early on, but they began to make the most of their home advantage.
Tyler Weir was unfortunate to see his dangerous cross beat everyone and go out for a goal kick.
Chorley may have thought they should have taken the lead on 32 minutes when Whitham’s cross found the head of Stephenson, unmarked in the area, but his header ended up narrowly wide of the goal.
And Worcester punished the miss.
A good run down the right by Tyler Weir was equalled by his pass to Nti, who slotted past Sam Ashton from 10 yards.
When it looked like the home side may carry an advantage into the break McDonald headed past his own keeper in the brink of half team following a Whitham corner.
A rejuvenated Chorley came out after the break and it took just ten minutes of the second half for Stephenson to put his side into the lead.
A good cross by Josh Hine was controlled neatly in the area by Stephenson who then beat Vaughan at his near post.
Worcester were restricted to efforts from range as they tried to pull themselves back into the game, but Ashton wasn’t troubled, much to the frustration of home supporters.
With just twelve minutes to go Worcester gave themselves a lifeline.
The impressive Nti took aim from a free kick and gave Ashton no chance from 25 yards out.
The game appeared to be petering out for a draw, but when Sean Geddes fouled Marcus Carver on the half way line he received his second yellow card of the game, and Worcester’s fourth red in five games this season.
And Chorley made the man advantage count.
Guy made the most of some poor defending, finding himself unmarked at the far post and was able to put the ball into the back of the net for a deserved victory.
