1970 Amateur World Series

The 1970 Amateur World Series was held in Cartagena, Colombia from November 18 through December 4, 1970. It was the first Amateur World Series in over 30 years to feature a European team and was the first to include two European teams, in the form of Italy and the Netherlands. It also marked the debut of Canada in Amateur World Series play.

The tournament was won by Cuba, for their second consecutive title and their fifth in the past eight editions. The United States finished in second, also for the second consecutive year.

The Italian and Dutch national teams were both fixtures of the European Baseball Championship, but neither had ever appeared in an Amateur World Series tournament until 1970. They would be the first European teams in the tournament since Great Britain defeated the United States in the inaugural Amateur World Series in 1938. While Italy and the Netherlands both won a game, the newcomers clearly struggled; nevertheless, within 35 years, both would make it to the medal round of the tournament.

This was the second year of competition for the United States national baseball team, which returned to the AWS after a near-three decade absence. Jack Stallings, head coach of Florida State University, managed the team.
