Phillies Hire Don Mattingly As Bench Coach

“I am excited to welcome Don Mattingly to Philadelphia,” Thomson said in this morning’s press release. “Having known Don for years and having worked closely with him in New York, I know that his knowledge of the game and his character make him a great addition to our tremendous coaching staff.”

Notably, Mattingly joins an organization that employs his son, Preston, as its general manager. The younger Mattingly isn’t the top decision-maker in Philadelphia’s front office — Dombrowski still holds hat role as the team’s president — but he’s a key figure in baseball operations who spent several seasons as the team’s director of player development and an assistant general manager before being elevated to his current post.

As Thomson noted in his comment, the two men worked together in the Yankees organization, though they didn’t overlap on the team’s major league coaching staff. Thomson actually succeeded Mattingly as bench coach in 2008, after Mattingly accepted an offer to become Joe Torre’s hitting coach in Los Angeles. He’d been in the running for the managerial vacancy in the Bronx that ultimately went to Joe Girardi, who named Thomson his new bench coach.

Even if they weren’t on the same big league staff, however, Mattingly and Thomson worked together with the Yankees. Mattingly was a minor league instructor prior to being added to the big league staff as hitting coach in 2003. During that time, Thomson worked both as a minor league manager and as a key figure in the Yankees’ player development department, where the two aligned to work with the Yankees’ up-and-coming talent.

In addition to his work as a bench coach and hitting coach between the Bronx and L.A., the now-64-year-old Mattingly spent five years managing the Dodgers and another seven managing the Marlins. He then jumped to the Jays, where he was first hired as bench coach and then had the title “offensive coordinator” added to his position. In that role, Mattingly oversaw the hitting coaches up and down the entire organization.

Now bound for Philadelphia, Mattingly will serve as Thomson’s top lieutenant. There’s been some speculation as to how long Thomson will continue to manage, but he signed a one-year extension through the 2027 season following the 2025 campaign, so he’s locked in for at least two more years. Mattingly is actually two years older than Thomson, so he’s not exactly the prototypical younger heir-apparent in waiting, but if Thomson does step away after his current contract, the Phillies would have an experienced option in the organization already. If not, Mattingly simply adds another seasoned coach to a veteran staff full of several well-regarded names.
