Nik Tzanev was an unused substitute as New Zealand's Under-20s were beaten 4-0 by the USA in their latest FIFA Under-20 World Cup match.
After drawing their opener 0-0 against the Ukraine this was always going to be the Young Ferns toughest Group A assignment.
And so it proved as Rubio Rubin headed home from close range to put the Americans ahead in the seventh minute.
Fulham midfielder Emerson Hyndman added a second before half-time and the points were wrapped up just before the hour when Paul Arriola slammed home from distance.
Rubin added a fourth late on to secure the USA's progress through to last 16 ahead of their final match against Ukraine.
New Zealand now face an uphill task to qualify as they need to beat Myanmar in their final match on Friday and hope other results go their way.
