Coldstream collected their first East of Scotland Premier Division victory of the season, despite playing for an hour with ten men.
Jonny Simpson was sent off for swearing at an opponent immediately after opening the scoring on the half-hour when he collected a sublime cross-field pass from Kris O’Neill to sweep into the net.
The forward, who had already been booked, swore during his goal celebration.
But Neil Oliver’s ten men doubled their lead before half time when Jake Rutherford showed pace and strength to hit the byline and cut back for John Crawford to stab home from close range.
Regan Graham’s corner was sliced into his own net by a Craigroyston defender early in the second half to make it three, but the home side pulled one back within a minute and went on to dominate territory and possession.
But Coldstream’s 10 men kept their shape well and defended stoutly. Goalkeeper Mark Walters was called on to make a couple of excellent saves as the pressure mounted, but for the most part the men in blue were comfortable soaking up the pressure and hitting on the break.
As Craigrosyton piled forward, Rutherford, Crawford and Josh Hebdon all came close to grabbing Coldstream’s fourth goal on the counter attack.
Coldstream: Walters, Powling, Hebdon, Ainslie, Allan, Devaney (Douglas 87), J Simpson, Rutherford, Crawford, O’Neill (Heugh 53), Graham (Coyle 59), Subs not used: R McLeod, Johnson.
