What happened: A wave of substitutions introduced Julian Zakrzewski Hall, Zavier Gozo and Mathis Albert for their senior USMNT debuts. The trio entered during a 4-1 victory over Peru at Inter&Co Stadium.
Why it matters: The playing time underscores manager Mauricio Pochettino's approach to evaluating dual-nationals early in his tenure. The federation commemorated the turnover by securing extra match balls for every new cap.
By the numbers: The USMNT camp roster featured 13 uncapped players, with 11 ultimately earning their first senior international appearances.
What to watch: The United States travels to St. Louis to host Chile on Sept. 29 to close the international window.
