The Portland Sea Dogs and Boston Red Sox today announced the extension of their Player Development Contract for an additional two years. With the move, the Red Sox will continue to have a Class AA Eastern League affiliate in Portland through 2022, the longest permitted term under the current Professional Baseball Agreement. The 2019 minor league season will mark the Sea Dogs 17th as an affiliate of the Red Sox. “We are excited to extend our partnership with the Sea Dogs,” Red Sox Vice President of Player Development Ben Crockett said in a release.
