Matt Gelb of The Athletic reports that Preston Mattingly, the son of former All-Star first baseman and manager Don Mattingly, has been promoted to general manager of the Philadelphia Phillies on Friday. Sam Fuld, the general manager since December 2020, is studying for his Master of Business Administration degree at the University of Pennsylvania’s Wharton School and will become the team’s president of business operations when he receives his degree in May 2026.
Until then, Fuld and Mattingly will split general manager duties under the president of baseball operations Dave Dombrowski.
Phillies Promote Preston Mattingly to GM
Fuld, 42, transitions to a new role after playing in the majors from 2007-15. Fuld went to Stanford and majored in economics. He was viewed by many in the game as a future front-office member, getting hired by the Phillies in 2016 as major league player information coordinator. While Fuld was general manager, all decisions ran through Dombrowski. Fuld assisted in transactions and negotiations. However, many of his responsibilities focused on everything else but the 26-man roster.
Mattingly, 37, rises to general manager as a highly regarded executive. The Phillies hired him to oversee minor league operations in 2022 and promoted him to assistant general manager in 2024 to prevent other teams from recruiting him. Mattingly played minor league baseball from 2006-11 and later captained Lamar University’s basketball team, graduating with a bachelor’s degree in 2016. He worked for the San Diego Padres from 2017-21, becoming coordinator of major league advance scouting and game planning.
In addition to the moves, Luke Marton was promoted to director of player development. Edwar Gonzalez was promoted to the director of hitting development. Mattingly is expected to still have an active influence on the farm system.
The elder Mattingly was a six-time All-Star for the New York Yankees from 1982-95. He then managed the Los Angeles Dodgers from 2011-15 and the Miami Marlins from 2016-22. He now serves as a bench coach for the Toronto Blue Jays.
