The Gregg Berhalter era opened with a 3-0 victory over Panama thanks to United States debutant Djordje Mihailovic, Walker Zimmerman and Christian Ramirez.
Berhalter was appointed head coach in December, the former Columbus Crew boss replacing Dave Sarachan, who had temporarily filled the void left by Bruce Arena in October 2017.
And USA – in rebuild mode having failed to qualify for the World Cup for the first time since 1986 – got a glimpse into the future in Arizona, where a youthful team defeated regional foes Panama in a friendly on Sunday.
Chicago Fire's Mihailovic opened the scoring in the 40th minute before defender Zimmerman and substitute Ramirez sealed the win during the final 10 minutes at State Farm Stadium.
