Philadelphia — A sensational rumor is circulating in MLB circles that legendary Don Mattingly could join the Philadelphia Phillies’ coaching staff as a bench coach, with his son, Preston Mattingly, now serving as general manager, potentially creating a powerful father-son duo running the organization.
Mattingly, a six-time All-Star with a long history as a coach and manager, is considered the ideal candidate for the Phillies’ bench coach position. Especially since Preston is already the general manager, the father-son duo could directly influence the team’s strategy, culture, and long-term direction.
The timing of the rumor is especially heated as Mattingly just finished his role as bench coach with the Toronto Blue Jays after the 2025 season and has publicly stated his willingness to take on new opportunities. Meanwhile, the Phillies were looking for an experienced bench coach who could act as a bridge between the locker room and the front office, and Mattingly was seen as the perfect fit.

Preston Mattingly, who was promoted to general manager in November 2024, is no stranger to the management world; he has held positions from director of player development, to vice general manager, to general manager, and has the full trust of president of baseball operations Dave Dombrowski. Adding Don Mattingly to the coaching staff, along with Preston’s presence as general manager, was seen as a strategic move to strengthen the team’s authority, consensus, and organizational culture.
The father-son combination has many benefits; Mattingly brings experience, credibility, and leadership to the locker room, while Preston will ensure a strong connection between the coaching staff and the senior leadership. Furthermore, having a powerful family story within the organization can also create excitement for fans and inspire players.
However, important questions remain. Is Don Mattingly content with his role as a bench coach, or will managerial ambitions resurface? A father-son relationship in a professional organization requires clear boundaries to avoid conflict. Additionally, fans and pundits will be watching to see if the decision will pay off on the field or if it is just a symbolic move.
Sources have now confirmed that the Phillies have seriously discussed adding Mattingly to the coaching staff; inside information suggests that it is part of a long-term strategy to strengthen the roster, culture, and operations. If the deal goes through, it will be one of the most compelling stories in MLB, with a legend and his son leading a team that is competing for a championship.
Fans and media will continue to closely monitor developments in the offseason, as well as Don Mattingly’s next steps. This is more than just a coaching signing; it’s a strategic, emotional move that could reshape the Phillies for years to come.
