Source - Don Mattingly won't be back as Miami Marlins manager next season

MIAMI — Don Mattingly will not be back as manager of the Miami Marlins next season, a source told ESPN, confirming multiple reports.

Mattingly's contract expires when the season ends and he and the team have agreed that a mutual parting is best for both sides, according to multiple reports.

The Miami Herald first reported on the decision.

Now comes the Mattingly move, which means someone else will be in charge when the team gathers for spring training.

The 61-year-old has managed for 12 seasons, the first five with the Los Angeles Dodgers. All five of those clubs had winning records, three of them making the playoffs.

Sunday's news came on the sixth anniversary of the darkest day in team history, when Marlins ace Jose Fernandez and two other people died when their 32-foot boat
