A bizarre goal from Leigh Hinds gave Clyde the points in a 1-0 win at Stark's Park as Raith fell deeper into the relegation mire.
The on-loan Wimbledon striker tried to cross from wide on the right after 57 minutes, but the ball caught in the strong wind and swerved over the head of Raith keeper Samuel Monin into the far corner.
It was cruel luck on Rovers, who dominated most of the game, but couldn't turn their possession into goals.
Paul Browne came closest to giving them a deserved point when his header was cleared off the line by David Dunn before Salvador Capin was denied by a fine reaction save.
The home side exerted almost constant pressure in the final 15 minutes, but it was all to no avail and they now face a real fight to avoid the drop to the Second Division.
