Davey Johnson will return as the Washington Nationals' manager for one final season after he and the club formally agreed to terms on a contract for 2013.

Johnson, who will turn 70 years old in January, will move into a consultant role with the organization following the completion of this upcoming season.

The veteran skipper piloted the Nationals to a major league-best 98 regular- season victories and a surprise National League East title in 2012, marking the franchise's first postseason appearance since the Montreal Expos reached the NLCS in 1981.

Johnson's contract expired following the World Series, and it was uncertain as to whether the NL Manager of the Year finalist would come back or opt for retirement.

Since taking over the Nationals during June of the 2011 season, Johnson has compiled a 138-107 overall record.

The 2012 Nationals became the fourth team Johnson has guided to the playoffs in a distinguished 16-year managerial career highlighted by his leading the 1986 New York Mets to a World Series title. Johnson was also named the 1997 AL Manager of the Year after directing the Baltimore Orioles to a 98-64 record and an ALCS appearance that season.

Johnson, who also steered Cincinnati to back-to-back postseason trips in 1994 and 1995, sports a 1,286-995 lifetime mark in stops with the Mets, Reds, Orioles, Los Angeles Dodgers and Nationals.
