MIAMI (CBSMiami) – Reports started trickling out on Thursday that the Miami Marlins had hired Don Mattingly as their new manager.

It appears that move isn’t the only one Miami made on this day.

The Marlins previous manager Dan Jennings, who worked as the team’s general manager from 2013 until he took over operations in the dugout, has been dismissed.

The team confirmed the firing just hours after they hired Mattingly.

Michael Hill, the Marlins president of baseball operations, will handle the general manager duties as well.

“This is the continuation of the restructuring of our baseball operations department,” team president David Samson said in a statement. “We look forward to moving in a unified direction to reach our goal of becoming a championship-caliber ballclub that our fans richly deserve.”

Jennings joined the Marlins as their Vice President of Player Personnel in 2002.

In 2007 he was named assistant general manager, a role he kept until being named the Marlins GM in 2013 when Michael Hill was promoted to team president.

After the season ended for Miami, team officials said that Jennings would move back into his old job as general manager, for which he was under contract through 2018.

Jennings never returned to the front office though, and was not involved in any of the Marlins offseason decisions.

Owner Jeffrey Loria and Jennings always had a solid rapport but that seemed to change when the two disagreed about how to handle certain players during the season.

The Marlins are not expected to immediately name a replacement for Jennings.
