The Blues laid their home hoodoo is style as they stopped league leaders Workington in their tracks.
Goals in either half from Charlie Russell and Cole Lonsdale gave Clitheroe only their second home win since November.
It was therefore a first Shawbridge success for manager Phil Brown.
And the manner of the performance in upsetting a Workington side which had lost just once this season to open up a clear lead at the top of the BetVictor North-West Division again underlined the progress the Blues are making under the former Lancaster City boss.
Brown’s side had averaged a point a game from their opening nine matches but hit new heights in ending a four-game winless run with a victory that should have been even more emphatic against a visiting side which ended with 10 men following the dismissal of Sam Smith.
