Blanch has been picked in the country colts team after a standout performance in the mud at the Country Championships at Bowral earlier this month.

His consecutive appearances in the country schoolboys team makes it three straight Cockatoos appearances for Blanch.

It's a reward for his versatility. The 19-year-old Blanch prefers tighthead prop, but the cunning scrummager can play loosehead if required.

Blanch got the news via a text from Thunder president Peter Daley while at work.

"I could hear my phone going ballistic," he said.

He was shocked. Blanch didn't think he played that well for the Mid North Coast Axemen colts.

The team lost 12-10 to Illawarra before beating Far North Coast 22-10.

He found the going tough.

"The mud was ankle deep," Blanch said. "The playing conditions were terrible. You couldn't play to 100 per cent."

His great run continued with Thunder's historic first victory in the Lower Mid North Coast Rugby competition on Saturday.

Thunder knocked over Old Bar 22-10 in a fantastic come from behind victory.

Blanch scored a try in the match and was thrilled to be a part of something special.

"It was surreal," he said.

"I loved every moment of it."

Thunder coach Marc Minor said it was fantastic news for his club, and Blanch's selection in the team was well deserved.

"He's been working hard for us during the off season," Minor said of the skipper.

"He's really showed his versatility."

Thunder will take on Gloucester at home on Saturday, and Blanch looked forward to his golden run continuing.

He said the visitors would be tough.

"Apparently they're a more physical team than Old Bar, and they [Old Bar] bashed us around a bit," he said.
