Nationals retain Mike DeBartolo; Parting ways with assistant general managers Eddie Longosz and Mark Scialabba

12:21 p.m.: DeBartolo will remain in Washington’s front office, Ghiroli reports in a follow-up.

12:19 p.m.: Assistant general managers Eddie Longosz and Mark Scialabba will not return to the Nationals in 2026, Britt Ghiroli of The Athletic reports. The departures are part of what appear to be multiple changes made under new president of baseball operations Paul Toboni, as Ghiroli writes that “several scouts and team staff members in Florida” are also departing.

It’s no surprise that Toboni’s hiring sparked a personnel overhaul, since some prominent names left the organization even before Toboni was hired two weeks ago. Since early September, former director of scouting Danny Haas and senior director of amateur scouting Brad Ciolek have each left the Nats to work with the Orioles and Tigers, respectively. It’s fair to wonder exactly how many members of Mike Rizzo’s front office will continue with the Nationals under Toboni — most notably, assistant GM and former interim GM Mike DeBartolo’s role with the team remains unclear.

Rizzo himself shook up the front office and player development teams a few years ago, but Longosz and Scialabba were two of Washington’s longtime employees who stayed put. Longosz started with the Nats in 2010 and worked as the club’s director of scouting operations for the eight seasons before his elevation to AGM and vice president in 2023. Specifically, Longosz was assistant general manager of player development and administration.

Scialabba’s ties to the organization go back even further, as he first joined the team in 2006. Working as the Nationals’ director of minor league operations from 2009 to 2013, Scialabba took over the player development department in 2013 before becoming assistant general manager of player development following the 2019 campaign.
