Johnson managed the New York Mets to the 1986 championship and later guided Cincinnati and the Orioles. He returned to managing in 1999 with the Los Angeles Dodgers for two years.
In June 2011, Johnson was working as a senior adviser with the Nationals when Jim Riggleman suddenly resigned midway through the season. Johnson took over and agreed to be part of a search committee to select a manager for 2012, allowing that he could be a candidate for the post, too.
The Nationals finished 80-81, barely missing out on their first winning season, and Johnson was brought back for another try.
Washington was without major league baseball for more than three decades. The Senators moved to Texas after the 1971 season, then the Montreal Expos moved to D.C. to start in 2005.
Under Johnson, the Nationals put aside their losing past and set up a winning future.
The same is true of the A's. Fired by the Diamondbacks early in 2009, Melvin was hired as Oakland’s interim manager on June 9, 2011. Three months later, he signed a three-year contract that runs through the 2014 season.
