Berhalter has 22 guys left in camp for the Costa Rica friendly.
Four guys gone from the initial camp:
J.T. Marcinkowski (#4 GK, really there only for U23 evaluation)
Paxton Pomykal (sent home a week or two to continue his rehab since he was never 100% fit following offseason surgery)
Cristian Roldan
Jordan Morris (both prepping for the Sounders' CCL campaign)
