With six games remaining this match took on a must-win feel for a Montrose Roselea side in last chance saloon.
Four or five wins might be required to achieve Premier League survival so a win against the second bottom side was crucial.
James Collier, who missed out at Dalkeith due to injury, was now suspended for two games so sat out again.
Roselea won a free kick in five minutes and Rae swung in a great free kick but there were no takers as the ball raced across the face of the Oakley goal.
Oakley then sent in a corner and Watson did well to block a header which was goalbound.
Watson had a chance at the other end in 16 minutes when he turned a Mitchell corner goal bound but Adamson pulled of a reaction save.
On the half hour mark there was a chance for both sides.
Allan was put through for Oakley but Mcleod blocked with his feet then Sturrock broke away but could not find support in the middle
In 47 minutes Scott Watson thought he had given Roselea the lead when he hit a great left footed shot which hit the corner of the bar before bouncing down and to safety.
It turned worse for Roselea in 50 minutes when they fell a goal behind.
Sturrock was caught under the ball and when McLeod parried the first shot out FLEMING followed up to score from close range
Reoch was denied the equaliser after his header was turned over the bar by Adamson
Calum Rae received a second yellow in the 80th minute and was unlucky as Carruthers lunged into the tackle.
Whyte went close with a header from a Taylor cross in 82 minutes but the 10 men of Roselea could not press Oakley and they held out for a good win.
This was a devastating blow to Roselea’s survival chances and they will now need to win at least four if not all of their last five games.
It was a poor match to watch on a very dry surface and a draw would have been a fair result, although not much good to Roselea.
Roselea have a free week on Saturday, March 26 before heading to their last trip over the Forth Bridge to Bathgate Thistle.
The Roselea bus will leave the Golf Inn at 11.00am.
The Montrose Roselea player of the month award went to Calum Rae who received his award from Kayleigh Johnson of the sponsor Chop. Calum had played in big part in the four draws the club had during that period.
The club extends their thanks to Michael Holm of Chop.
