Raith's dreadful run of form at home continued as Clyde moved above them in the table with a deserved 2-1 victory.
A goal in each half consigned Rovers to their sixth game in a row at Stark's Park without a win and all but ended in their fading title hopes.
In a poor game Clyde provided what little entertainment there was and were good value for the three points.
French striker Frederick Bonniface sent them on their way after 17 minutes with a fierce 25-yard free-kick which deflected off the head of Brian Hetherston and flew into the top corner.
Raith did draw level before the break but had to rely on an opposition player putting the ball in the net, Greig McCulloch's cross sliced past his own keeper by Darren Murray.
The home side toiled after the break and Clyde's winner came in 62 minutes when Pat Keogh rose highest in the box to bullet a header into the roof of the net.
Rovers did have the ball over the line late on but it was ruled out for offside.
