Ryan Frances scored the only goal of the game as 10-man Clyde beat Berwick 1-0.
The hosts had a number of chances to take the lead in the first half but they struggled in front of goal and it remained goalless at the break.
Clyde dominated in the early stages of the second period and it was not long before they took the lead.
Frances netted his second goal of the campaign in the 48th minute when he nodded the ball past Berwick stopper Paul Grant from the middle of the box.
The visitors were reduced to 10 men nine minutes later when Iain Gray felled Darren Lavery.
Berwick nearly drew level in the closing stages of the second half when Neil Janczyk unleashed a left-footed effort from inside the box but he was denied by the post.
