Levitt was given his senior international debut by club legend Ryan Giggs and he finished the game in Helsinki on the winning side, thanks to an assist from current Reds winger Dan James.
The latter was Wales' main attacking threat, not only delivering the pinpoint ball for Kieffer Moore to make it 1-0 to the visitors in the 80th minute but also crossing for the same Cardiff City striker to head home in the first half - only for that effort to be disallowed.
Giggs selected Levitt in his Welsh squad for previous fixtures but kept him out of the fray, delaying his debut, when the stakes were particularly high.
