Wochit News - Former baseball star Don Mattingly is heading to Florida. Mattingly, who left the Dodgers after five years in charge, becomes Marlins' seventh manager since June of 2010. Mattingly is hoping to put an end to the Miami Marlins' managerial merry-go-round. At a press conference Mattingly commmented, “I signed a four-year deal but I plan on being here at least 10." With the change he'll face a big adjustment regarding resources.
