Nigel Davies says the Scarlets' young guns came good as they saw off Wasps18-13 at Adams Park to edge closer to an LV= Cup semi-final.
But it could have been a very different analysis had the battle of the boots gone the way of the home fly half.
Scarlets fly-half Rhys Priestland kicked six penalties, but his opposite number Dave Walder, missed four of his five attempts at goal.
Walder's misfiring boot meant that despite two fine tries by Tom Varndell, Wasps' hopes of progressing in the tournament were dealt a blow.
"This experience has been huge for the young guys we've selected in recent weeks and I am delighted for them," said Davies.
"While some times it has been painful for them in difficult games, we are seeing the rewards. I am absolutely delighted with the lads, and Rhys showed he can handle the pressure of kicking difficult goals in a very big game.But also, he showed other aspects of his game are developing at a pace."
Scarlets hooker Matthew Rees did enough on his return from injury to show he is ready for a return to international action in Wales' Six Nations opener against England at Twickenham next weekend, according to Davies.
"I back Matt to go into the Wales team for Twickenham," said the Scarlets coach.
"He's fit and he's fine, as he showed with his performance here, especially in the lineout."
Rees hailed Priestland's kicking display as Scarlets' trophy hunt continued.
"Rhys is a great player who will get better with age and experience. He kicked his goals brilliantly," said the hooker.
"We're in the Amlin Cup quarter-finals against Toulon and now we have a great chance of making it into the last four in this one."
Priestland added: "Our ability to close games out in a tremendous boost and winning four on the trot is also something that takes a monkey off our backs.
"The forwards were again fantastic in taking the pressure off us because Wasps played the better rugby and we showed our character making almost three tackles to every one they made."
