Michael Daly scored the only goal of the game as Clyde edged out Berwick 1-0 at the Broadwood Stadium.
Ryan MacBeth had the first chance for the hosts, who saw Paul Grant fumble his save before smothering it at the second attempt.
The visitors' best opportunity fell to Douglas Brydon but he failed to direct his header just before the half-time whistle.
Lee Currie went a little closer after the break with Rangers slowly starting totake control of the game.
But they were shocked on 73 minutes when Daly ghosted into the box unmarked to head home John Sweeney's corner.
Darren Lavery and Josh Morris both went close for the visitors but neither could find a way past goalkeeper Jamie Barclay in the closing stages.
