What happened: Justin Ellis and Peyton Miller are making their senior debuts for the USMNT alongside starter Cavan Sullivan. Tyler Adams takes the captain's armband for the match against Peru.

Why it matters: The lineup reflects a youth movement under Mauricio Pochettino, who is handing 11 players their senior USMNT debuts today. Sullivan enters the starting XI just two days before his 17th birthday, becoming the youngest American to feature since Freddy Adu.

What to watch: The federation secured extra match balls to supply the large volume of uncapped players taking the pitch.
