The Nyngan Tigers will rue missed opportunities outclassed by co-competition leaders Orange CYMS 54-10 at Wade Park.

It means they are now teetering on the edge of missing the finals series and need luck and results in other games to go their way.

Winger Connor Elwood's first-half storming run down the far right edge showed Nyngan were in the match on 12 minutes but a glut of possession didn't eventuate in further points.

Eventually down 24-4 it was going to take something special to come back.

But CYMS shut Nyngan out in the second half to win easily.

Tigers centre Terrence Ryan did step through the middle to bustle through to score late but it was game gone by that time.

This day had everything - a COVID scare forcing a referee to not officiate late and Orange CYMS first grade captain-coach Jack Buchanan became a touch judge in the Under 18s match to replace the sick official while 4 players from Orange helped Nyngan field a team who finished the game with 12 men losing 44-4.

There was a bright spot for the Tigers their reserve grade side is finals bound winning 24-12 Mathew Sheather and Keenan Ellwood grabbing doubles in a torrid match.

The Tiger's big attack laying the platform. Impressing in the run to season's end.

League Tag produced some sparkle from the Tigers albeit losing 24-10 in the second half Nyngan scored 2 tries and look certain for finals football despite defeat.

Big guns first grade Dubbo CYMS, Forbes Magpies both had first grade victories.
