Berwick manager Ian Little was disappointed at seeing his side lose their second home game in a week, but he intends to stick with his principles of playing open, attractive football.
He said: “I think this is the best footballing side we have had here at Berwick in my seven years as a player and manager.
“They say football is all about small margins and that couldn’t have been better emphasised today. We must have had 20 chances, while Clyde only had one and scored the only goal of the game.”
Clyde, after beating Berwick on the opening day of the season, completed the double with a classic smash-and-grab raid.
Rangers were the better side but even when the visitors were reduced to 10 men early in the second half the Borderers were unable to take advantage.
In the first half Scott Dalziel was unlucky when he saw a back-post header come back off the woodwork, while Steven Notman had three shots at goal, one of which was grasped by goalkeeper Jamie Barclay.
At the start of the second half Darren Lavery pushed a shot wide of the upright, but just seconds later, in the 46th minute, Clyde, in a rare attacking move, scored the only goal of the game.
A long throw from John Sweeney on the left was met with a looping header by Ryan Frances in the packed goalmouth and the ball found its way into the top corner of the net.
After 56 minutes Clyde were reduced to 10 men when Iain Grey was red-carded for a foul on Lavery in the middle of the pitch, and in the ensuing melee a further two players were booked by referee Colin Stevens.
Berwick then lay siege to the Clyde goal. Damien Gielty headed over with the goal at his mercy. Kenny O’Brien brought out a fine point-blank save from Barclay whilst substitute Ross Gray shot straight at the goalkeeper.
