As the 2021 season approaches, MiLB.com introduces the 11 leagues created by the restructuring of the Minor Leagues across four levels of play. Below is a team-by-team introduction to the Triple-A East, including previous circuit and most recent championship. (Note: "Established" refers to the first year of a team's continuous operation in that market regardless of league or level.)

In this 20-team league, the largest in the Minors, 14 clubs come directly from the Triple-A International League. One of those, Worcester, will debut in a new ballpark and a new town as the Pawtucket franchise moves 35 miles northwest from Rhode Island into central Massachusetts. Meanwhile, four of the clubs (Iowa, Memphis, Nashville and Omaha) arrive from the Triple-A Pacific Coast League, one (Jacksonville) joins from the Double-A Southern League and the other (St. Paul) enters from independent ball. With a geographic range from New England to the Plains, from the Deep South to the Canadian border, the Triple-A East is comprised of three divisions spanning 14 states -- a spread that could eventually prep players for the Majors in more ways than just on-field development.

Fans and friends, bleacher creatures and box seaters, meet your Triple-A East teams:
