Don Mattingly (61) will not return as the manager of the Miami Marlins for the 2023 season.
Mattingly and the Marlins mutually agreed on the decision. His contract is set to expire at the end of the season.
"We are fortunate to have had Don Mattingly leading our team on the field over the last seven years," Marlins' principal owner Bruce Sherman said in a news release Sunday.
"He has represented the Marlins, our players, our fans, and the South Florida community with unmatched dignity and pride. Over the course of our recent conversations with Don, we both agreed not to pursue a new contract for the 2023 season and that the time is right for a new voice to lead our clubhouse."
Mattingly will manage the remainder of Miami's games this season, then return to his hometown of Evansville, Indiana.
"I am proud and honored to have served as manager of the Marlins for the past seven years and have enjoyed my experiences and relationships I've developed within the organisation," Mattingly said in the release. "I look forward to spending time with my family in Evansville, and to any future endeavors.
