After the Mets won the final game of their season with a walk-off home run in extra innings Sunday, Manager Mickey Callaway quickly transitioned to lamenting the fact that his team would again have to watch the playoffs instead of competing in them.

“The next month will suck,” Callaway said after the Mets missed the postseason for the third straight season.

It got worse for him on Thursday. Jeff Wilpon, the team’s chief operating officer, and General Manager Brodie Van Wagenen flew to the Florida Panhandle in the morning to meet with Callaway, who had previously announced his plan to drive 19 hours from Queens to his off-season residence in Santa Rosa Beach. After listening to the manager’s assessment of the team and sharing feedback, they decided to fire Callaway, who finished his two-year tenure with a combined record of 163-161.

In a conference call with reporters after the announcement of the move, Van Wagenen and Wilpon commended Callaway for what Van Wagenen described as the manager’s “perseverance through this season’s many, many ups and downs.”
