What happened: The United States struggled for spacing through the opening 20 minutes with the left side rotating. Hall attacked behind the line while the rest of the shape stayed condensed.

Why it matters: The lineup features four first-time starters with Reyna as the only holdover from the 4-1 win over Peru. Early congestion tests how quickly the new group finds combinations.

What to watch: Watch whether the left-side rotation settles and opens space for Hall's runs.
