It was Young's highest score (previous best 121) while fellow Taranaki batsman Bruce's 85 suggests the youngster is not just the find of this summer but will create more headlines in seasons to come.
Not to be outdone, ND skipper BJ Watling, playing his 100th first-class game, declared at 273-8.
Said Van Wyk: "We don't want it to come April and not giving ourselves a chance to win matches.
"I'd much rather be sitting here tomorrow night knowing I've given us a chance to win rather than staring a draw in the face."
The wicketkeeper said it was imperative the youngsters in the CD team become accustomed to nurturing a steely fortitude in eking out results in four-dayers.
"They won't learn anything if we play out a draw.
"It means we should be prepared to lose a game to win so they'll be learning how to take risks by playing aggressively."
Van Wyk saluted Young's adroitness and Bruce's patience as well as seasoned Greg Hay's graft and fighting skills.
Today won't be easy but he said if the Stags make them toil then lethargy would creep in and make it easier for them to score runs.
