ORANGE CYMS have come away from a fiery final round Group 10 clash with an important 30-12 victory over St Pat's on Saturday.

In a stop-start encounter marred by a biting allegation, the green and golds raced in 20 unanswered second half points to assert their ascendancy over the fifth-placed Bathurst outfit.

Failing to return in the second half with a groin issue, CYMS player-coach Mick Sullivan slammed the bite claim on gun back rower Riley Law. It came late in the clash.

"There were a couple of disappointing incidents to come out of the game, but things have to be proven. It's a big thing to say someone's done something like that ... usually teeth leave a mark. I didn't see one," Sullivan said.

"If you're a footy player and you whinge about it, there has to be something to show.

"That's up to other guys to decide, but I'd like to see some evidence."

Pat's coach Kurt Hancock did not comment on the incident.

The biting allegation is just one of a handful of events for the match review committee to look over this week, with both Riley Law and Kyran Bubb placed on report during the 80 minutes.

The game had several spot fires - Pat's hooker Benjamin John and Semisi Katoa's melee in the second half the most eventful - but CYMS' stamped their authority on the match with a mix of flare and muscle.

Trent Rose and former Saint Simon Osborne were the main ingredients in a dominant victory over a tough St Pat's.

"We are a physical side and we get up and in," Sullivan said.

"I thought we were on top [in the first half] but the feeling was I was letting us down on our edge.

"We put Peckers [Luke Petrie] out there and we stayed stable on the right and it gave us a bit of a chance to attack. The points flowed and our defence was good."

It was a welcome return to form for minor premiers CYMS, who dropped last weekend's penultimate round clash with the Dragons 22-20 in Mudgee.

And at Wade Park on Saturday, early on at least, it looked as though St Pat's were capable of emulating the Dragons, with flying winger Adam Morton scoring a great try after 13 minutes.

Garry Reilly nailed the conversion and the visitors led 6-0.

CYMS hit back with Sam Hill scoring a soft try out of acting half, before Trent Rose picked up his own four pointer. His boot then landed one of the two conversion attempts to shoot the hosts out to a 10-6 lead after 26 minutes.

But, almost immediately, Pat's benefited from a penalty out of the game's first minor scuffle and hit back though John. The star rake barged his way over to ensure his side went into the break up 12-10.

CYMS, though were not about to give up on a day they celebrated their 70th anniversary.

Filling in for Sullivan in the halves, Petrie sent Katoa in for his first of the match six minutes after the resumption of play. Then, in a moment of magic, Trent Rose produced a Matt Gidley-esque flick pass on CYMS' left edge to allow Wayne Collett to score out wide.

Rose then nailed the sideline conversion to give the hosts a 22-12 advantage.

Successfully booting a penalty goal from right in front, Kyran Bubb bumped that lead out to two converted tries with 17 minutes to go. Katoa put the icing on the anniversary cake with brilliant run down the right flank to score a brace, Matt Rose sending the conversion over on full-time to send the vocal home crowd into raptures.

St Pat's will now now face Blayney in the minor semi-final.

ORANGE CYMS 30 (Semisi Katoa 2, Sam Hill, Wayne Collett, Trent Rose tries; Trent Rose 3, Kyran Bubb, Matt Rose goals) defeated ST PAT'S 12 (Benjamin John, Adam Morton tries; Garry Reilly 2 goals)
