Jon Heyman first reported that Martinez, 53, will be announced as the new manager after the World Series.
Two sources familiar with Grandpa Rossy's situation and the team's thinking framed it like this: Ross would be on the short list of ideal candidates to become Joe Maddon's bench coach, but it's also doubtful that the timing will be right for someone who is raising a young family in Florida and has so many off-the-field interests.
Martinez replaces Dusty Baker, who was let go when his two-year contract ended this season. But while the money behind Martinez's deal is not immediately clear, the length of the deal signals recognition of the state of the managerial market (Cora and Ron Gardenhire got three years each to manage the Red Sox and Tigers, respectively).
In the Nationals, Martinez will inherit a team with a stellar bullpen, MVP-caliber player Bryce Harper and a strong lineup, but it remains an organization unable to break through the NLDS.
In a conference call earlier in October, Nationals General Manager Mike Rizzo called Baker "a Hall of Fame-type manager", but said that the expectations of the team had grown along with their success. Before that, Martinez worked for Maddon with the Rays. When Maddon became the manager of the Cubs before the 2015 season, Martinez followed him to Chicago.
Martinez gives the Nationals a different look - a fresher face than Baker or Davey Johnson, but a more relaxed leader than Williams. The Red Sox and Mets each hired first-time managers and gave each of them three guaranteed years, establishing a baseline for negotiations with Martinez. He has interviewed for several openings in recent years, including the Nationals job four years ago, but to date has not been selected.
