1973 Amateur World Series (in Nicaragua)

The 1973 Amateur World Series in Managua, Nicaragua was run by FEMBA, a splinter organization from the International Baseball Federation (FIBA). It ran parallel to FIBA's 1973 Amateur World Series in Cuba, during a period of international baseball conflict.

Though the FEMBA event started and ended earlier, it went into the history books post-reconciliation as "Amateur World Series XXII" while the FIBA event was known as "Amateur World Series XXI". The FEMBA Series was held in Managua, Nicaragua from November 22 through December 5.
