[1][2] The tournament occurred shortly after the 1968 Olympic Games, also in Mexico City, though it was not considered part of the Olympic program.

It was billed as the first edition of the tournament, but the format was not continued; future international amateur tournaments, including the following year in Santo Domingo, would continue to bill themselves as the Amateur World Series.

[3] It lost only one game, in a ten-inning shutout to Mexico.

[4][5] The U.S. team included several future major leaguers, namely Brent Strom, Larry Gura, Lenny Randle, and Steve Rogers.

Other future major leaguers included Puerto Rico's Miguel Fuentes.
