Washington Nationals hire 31‑year‑old Ani Kilambi as GM, the youngest in MLB, after he left the Phillies where he expanded their research department.
A Major Move for the Nationals
Washington’s front office announced that former Phillies assistant general manager Ani Kilambi will become the club’s next general manager. The appointment makes Kilambi one of the youngest general managers in Major League Baseball.
The Nationals’ decision comes roughly seven weeks after the club hired 33‑year‑old Blake Butera as its manager, signaling a broader shift toward younger leadership. Washington has finished last in the National League East in five of the past six seasons, a factor that likely influenced the move.

Kilambi’s Background and Rise
Kilambi, 31, joined the Phillies in 2021 after spending six seasons with the Rays. In Tampa, he served as director of decision science and assistant director of research and development. Prior to his baseball career, he earned a bachelor’s degree from the University of California, Berkeley, double‑majoring in Statistics/Operations Research and Management Science.
With the Phillies, Kilambi oversaw the research and development department. The organization significantly expanded that area under his direction. According to The Philadelphia Inquirer, the department nearly doubled in size during Kilambi’s first two seasons. With the support of president of baseball operations Dave Dombrowski and then‑general manager Sam Fuld, an organization once viewed as lagging behind analytically became one of the stronger research groups in the sport.
The Phillies’ Front‑Office Shake‑Up
The Nationals’ hiring of Kilambi leaves the Phillies without a key member of their front office. Jorge Velandia, hired in 2020, remains the club’s other assistant general manager. It is not yet clear whether the Phillies plan to fill Kilambi’s role before the season.
Dave Dombrowski spoke with the media on the state of the Phillies’ outfield on Tuesday, underscoring the front‑office changes and the organization’s focus on analytics.
Key Takeaways
- Washington Nationals hire 31‑year‑old Ani Kilambi as general manager, the youngest in MLB.
- Kilambi previously oversaw the Phillies’ research and development department, nearly doubling its size.
- The Nationals’ shift toward younger leadership follows the hiring of 33‑year‑old manager Blake Butera.
The move positions the Nationals to build a new core around a young, analytically minded front office, while the Phillies adjust to the loss of a key executive.
