The Chicago Cubs made a big announcement on Wednesday morning, revealing that they had agreed to Player Development Contract extensions with all five of their minor league affiliates.

According to a press release issued by the team, they agreed to a four-year contract extension with the Single-A Eugene Emeralds and two-year contract extensions with the Triple-A Iowa Cubs, Double-A Tennessee Smokies, and the Single-A Myrtle Beach Pelicans and South Bend Cubs.

The contracts extend the PDC’s with all five clubs through the end of the 2022 season.

“We could not be happier to extend our five affiliates through at least the next four seasons. The clubs have been wonderful partners for our players both on the field and in their respective communities,” said Jason McLeod, the Cubs Senior Vice President, Scouting and Player Development. “Continuing these relationships with our affiliates is a testament to each club’s leadership, first-class staff and facilities and loyal fan bases.”

The Cubs have partnered with Iowa since the 1981 season, and first began an affiliation agreement with Tennessee in 2007, according to the press release.
