Raith returned from their maiden visit to St Mirren Park with all three points following a dramatic late win.
Raith were well worth their victory having shown ruthlessness up front mixed in with some terrific last man defending at the back.
Raith were clearly revelling under the floodlights and took a deserved lead on the 12 minute mark.
Saints failed to clear their lines from a Ryan McCord free-kick and the ball broke kindly to James Craigen on the edge of the box.
He needed no invitation to have a pop and curled a delightful effort around Jamie Langfield.
Any fears that the opener would somehow jilt the sluggish hosts into life were unfounded and it was Raith who remained on the front-foot.
Jamie Langfield had to look lively to turn a Mark Stewart header around the post as Raith continued the threaten.
St Mirren, one of the pre-season tips for promotion, weren’t at the races and wasteful in possession.
Raith were unlucky not to extend their lead when a cross flashed along the six yard box evaded McCord and then Jon Daly by a matter of inches.
The fans were already starting to stream down for their half-time pies by the time it took the hosts to have their first chance of goal.
Lawrence Shankland’s glancing header was on target but comfortably held by Kevin Cuthbert.
Shankland wasn’t to be denied, though, and he pulled Saints level when he finished off a slick move forward.
The home side picked up in the second half from where they left off in the first.
They went straight on the attack with Shankland in particular causing constant problems.
At the other end a Daly header was comfortably saved by Langfield.
A point would have been a great return for Raith but in the dying moments they snatched all three when Daly’s header beat Langfield.
