Sam Warburton (with ball) and Craig Mitchell got their first taste of international rugby on tour.
Duncan Jones has urged Wales Young Guns to continue firing their bullets when they get back to their regional environment.
Scarlets full back Daniel Evans and centre Jonathan Davies along with Cardiff Blues youngster Sam Warburton all got their first taste of international rugby as did Ospreys wing Jonathan Spratt and prop Craig Mitchell.
"On the field and off the field, the young players have stepped up," said Jones, who finished the match against USA as captain after Ryan Jones had to leave the field with an injury.
"It hasn't just been the more experienced voices you've heard in training. The younger boys have listened well, but they've also contributed and pulled up some of the senior guys on things they've been doing wrong.
"That's the environment the boys and the coaches have created where everyone is equal and everyone has their say. I think the youngsters will all be pleased with their individual performances at the weekend, but hopefully they'll take a look at the video the same as everyone and realise the mistakes they've made.
"You never have the perfect performance, whether you've got one cap or 50 caps. It's how you go away, it's how you take that information on board and I'm sure they will do it in the right way."
"It's their first taste of international rugby and what you hope is it's given them a taste of what it's about and that they don't just rest on that and are happy with what they've achieved.
"It's about everyone pushing each other for that jersey and I have every confidence the young boys you've seen on this trip will do that."
