CHICAGO — Davey Johnson was poised Saturday to take over as manager of the Nationals, replacing Jim Riggleman, who abruptly resigned two days earlier.
General manager Mike Rizzo told Fox that Johnson has agreed to terms, but there are still contract details to be worked out before an announcement can be made.
It will be Johnson’s fifth managerial stop and first since he managed the Dodgers in 2000.
Johnson has been a senior adviser with the Nationals since 2009.
The 68-year-old Johnson managed the Mets, Dodgers, Reds and Orioles over 14 seasons and compiled a 1,148-888 record. His 1986 Mets team won the World Series.
