Cornish Pirates boss Ian Davies hailed his younger players after they came from 10-3 down at half-time to beat Doncaster 24-22 in the Championship.
It was the club's second successive win after losing their opening three games.
Summer signing Jamal Ford-Robinson, Tom Channon and Tyler Gendall all impressed as Pirates recorded their first away win of the season.
"Jamal probably had his best game in a Pirates shirt," head coach Davies told BBC Radio Cornwall.
"That's why we didn't reverse the yellow card for Jack Andrew because Jamal had come on and solidified the scrum, but his carrying was really good as well.
"That's what we want from him, but he's a young lad and if he keeps progressing he's got a big future," Davies said of the
Davies also commended 20-year-old former St Ives prop Tyler Gendall, who is in his first season of professional rugby.
"He's the deadly assassin. He says about three words in the week, but when he gets on the park you've got tot take your hat off to him.
"His work rate is phenomenal, his passion is brilliant, he's a lovely kid as well and he's another one with a big future ahead of him," Davies added.
