Don Mattingly will not be back as manager of the Marlins next season, he said Sunday, announcing that he and team officials have decided a new voice is needed to lead the club going forward.

Mattingly's contract expires when the season ends. He said he met with Marlins principal owner Bruce Sherman and GM  Kim Ng to talk about the future, and that "all parties agreed" that it's time for a change.

"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 organization," Mattingly said. "I look forward to spending time with my family in Evansville [Indiana], and to any future endeavors."
