“GUATEMALA CITY, Guatemala — A weathered, eight-lane track rings the field at Estadio Mateo Flores, site of the 2011 CONCACAF U20 Championship. Far from the pitch, on a narrow strip of real estate between lane eight and the near-empty stands, six young Americans juggle a single Nike ball. As I observe from the press box that doubles as a VIP area and triples as general admission seating, United States substitutes Cody Cropper, Eder Arreola, Moises Hernandez, Omar Salgado, Sacir Hot, and Sebastien Ibeagha stay loose.” Run of Play
