Phillies Name Preston Mattingly New GM; Sam Fuld Pursuing MBA, Will Return in 2026

The Philadelphia Phillies made multiple front office changes on Friday.

The Phillies announced that assistant general manager Preston Mattingly was promoted to vice president and general manager, a role that was previously held by Sam Fuld (via Todd Zolecki of MLB.com).

Fuld is pursuing his MBA at the University of Pennsylvania's Wharton School and will transition to Philadelphia's president of business operations following his expected graduation in May 2026.

Fuld was originally named the Phillies' general manager in Dec. 2020.

While president of baseball operations Dave Dombrowski still has the final say in the front office's decision-making process, Mattingly will have a larger role.

"The continued growth of Sam and Preston is remarkable," Dombrowski said, via MLB.com. "Both of them do a fantastic job, and these promotions provide continuity in the organization for years to come."

Fuld's duties as general manager will be divided with Mattingly "to accommodate his academic workload and increasing business operations responsibilities," per the announcement.

"I look forward to taking on this new challenge with the same passion, competitiveness and respect that I've applied throughout my professional career," Fuld said. "The opportunity to collaborate across baseball and business operations is an exciting one, and I'm honored to be entrusted with helping to build upon the many great elements of this organization."

Mattingly, the son of six-time All-Star and former Miami Marlins manager Don Mattingly, was initially hired by the organization as director of player development in Sept. 2021 after spending time with the San Diego Padres in scouting roles.

He was promoted to the position of assistant general manager in Nov. 2023.

In his new role, Mattingly will now look to help Philadelphia navigate the offseason and attempt to bounce back from a disappointing four-game defeat in the National League Division Series after finishing the regular season with the No. 1 spot in the NL East.

As the Phillies look to pursue a fourth consecutive postseason appearance in 2025, they'll have a revamped front office surrounding Dombrowski.
