SAN JOSE, Costa Rica (AP) — Standing on a sideline at Estadio Nacional, where a running track and 20-30 yards separate the field from the stands, Kasey Keller remembered getting hit on the head by a half-eaten hot dog during a World Cup qualifier at nearby Estadio Ricardo Saprissa, where fans were on top of players and the U.S. went 0-7 in World Cup qualifying. “Crazy” and “war” were some of the words the retired goalkeeper used. American players were hit with bags of urine, coins and batteries.
