This year has not been the best for manager Don Mattingly and his team, the Miami Marlins. Playing in one of the most lopsided divisions in baseball, Marlins fans would like to forget that 2022 ever happened.Jon Heyman@JonHeymanBreaking: Don Mattingly is telling the Marlins today he will be leaving as manager at the end of the year6544631Breaking: Don Mattingly is telling the Marlins today he will be leaving as manager at the end of the year"Breaking: Don Mattingly is telling the Marlins today he will be leaving as manager at the end of the year" - @ Jon HeymanThe team currently has a record of 63-90, putting it in fourth place in its division and 33.5 games behind the New York Mets.

He was also a successful manager in Los Angeles. He coached the Dodgers from 2011 to 2015 before coming aboard the Marlins as a manager.j_ackins@Jackscan04@JonHeyman Come to the Yankees please1@JonHeyman Come to the Yankees pleaseHITITHARD13@electric413@JonHeyman Let’s fire Boone and get Donny Baseball 6@JonHeyman Let’s fire Boone and get Donny Baseball ⚾️Following the announcement of his retirement, many Yankee fans expressed interest in having Mattingly come to New York. Only this time, he would be working his magic from the dugout.Current Yankees manager Aaron Boone has lost some popularity among the fanbase. This is despite the Bronx Bombers leading their division and looking poised for playoff success.joe@BurdenBurner@JonHeyman Come to New York🥲11@JonHeyman Come to New York🥲Aj Baalman@AjBaalman@JonHeyman Donny Baseball retiring?@JonHeyman Donny Baseball retiring?As manager of the Los Angeles Dodgers, Mattingly led the team to three consecutive division titles between 2013 and 2015. With the Marlins, Mattingly has been unable to match such success. He came closest in the shortened 2020 season, when the Marlins finished second in their division.Don Mattingly still as popular as ever with Yankee fansMiami Marlins v Los Angeles DodgersMattingly turned 60 last year. It is unclear if he is eyeing retirement or just a change. The decision was apparently made mutually by Mattingly and the Marlins management. Mattingly will leave the Marlins holding the record for the most wins and games managed as a manager.As for Aaron Boone and the Yankees, it looks as though they are doing fine the way they are. Perhaps the timing is just not right for Mattingly to be selected to manage his former team.
