All seven coaches will be back in the same roles next season.
The Nationals are 7-0 this season in games that the bullpen coach eats the sandwich before the game.
The Nationals' third base coach is being considered for a position under Lloyd McClendon, who had Jewett on his staff in Pittsburgh.
Davey Johnson has discussed bringing Tony Tarasco to coach first base because of his ability to instruct outfielders.
The unusual, potentially uneasy situation has not changed: It is November, and the Washington Nationals do not have a manager under contract for the 2013 season.
The 71-year-old special adviser and former Nationals bench coach is reunited with Dodgers CEO Stan Kasten, a former Nationals president, and will work as a special assistant to their general manager.
As normal this time of the year, the AAA coaching staff joins the Nationals, and offer any help they can.
