Substitute Christian Pulisic provided an immediate spark upon his return from injury, nearly shifting the momentum with two close opportunities that narrowly missed the target.
During a chaotic sequence in the 63rd minute, a deflected effort from Pulisic struck the crossbar before a follow-up attempt from McKennie was quickly blocked by Turkish defenders.
The decisive blow arrived in the final seconds when Güler evaded two defenders near the corner flag to deliver a precise cross to the far post.
Kaan Ayhan stood unmarked and made no mistake with his close-range finish, securing a positive ending for Turkey and leaving the host nation with urgent defensive questions.
