Joe Bell played a characteristically well-placed ball down the line for Jack-Henry Sinclair to run onto and pick out Moses Dyer just inside the box but the newly-named captain turned his effort agonisingly wide of the far post. It was as close as New Zealand would come and they were made to pay as the USA went on to take total control of proceedings with a scintillating offensive display.
Bazeley's side were enjoying one of their best spells of the game when the USA struck a telling second goal in the 64th minute, Jeremy Ebobisse spinning on the edge of the area before unleashing an unstoppable shot past Woud, who was again among New Zealand's best showings despite having to pick the ball out of his net six times.
With nothing to lose, Bazeley immediately responded by going on the front foot, bringing off well-performed defender Hunter Ashworth for playmaker Singh, but that tactical switch had little impact on the USA's momentum. Brooks Lennon burst down the right and finished calmly to make it 3-0 just seconds later and, from that point on, New Zealand could not cope with the American assault, Glad finally getting a goal to his name in heading home a corner in the 76th minute before substitute Auston Trusty came close to matching the quality of Ebobisse's strike with a similar effort in the 84th minute.
The New Zealand camp, several of whom did not have fond memories of playing the USA after falling 4-0 to the same opponents in the previous edition of the FIFA U-20 World Cup two years ago, were now keen to hear the final whistle but there was still time for icing to be spread on the American cake as another substitute, Lagos Kunga, completed the scoring in stoppage time.
Bazeley and two members of the U-20 squad - Clayton Lewis and Dane Ingham, both withdrawn after the second group stage match to join the senior national team - will hope to get over the disappointment quickly with a positive showing with the All Whites in the upcoming FIFA Confederations Cup in Russia.
