A person with knowledge of the move tells The Associated Press that Ani Kilambi is joining the Washington Nationals as their new general manager. The person spoke to the AP on condition of anonymity on Wednesday because Kilambi’s hiring had not been announced yet. The 31-year-old had been an assistant GM with the Philadelphia Phillies. Kilambi is the latest young face to join president of baseball operations Paul Toboni in Washington. Kilambi takes over a job that was held for more than a decade and a half by Mike Rizzo, who was the GM in Washington since 2009 and added the title of president of baseball operations in 2013. Rizzo was fired in July during Washington’s sixth consecutive losing season.
