Bolivia isn't exactly a CONMEBOL standout anyway, and with their domestic league still going they very much ran out a B side. But Robinson was generally composed, showed good recovery instincts on the couple of times he was out of position, and made effective runs forward at appropriate times.
He wasn't the only player to stumble on the left side at that end, so I wonder if it was part uneven pitch coupled with desire to impress.
A very young USA side all around, some good potential to be sure, but nobody aside from Pulisic I'd want playing significant minutes in the Premier League just yet. Julian Green may come good, and others showed signs, but the inexperience was extremely obvious.
