Matt Williams was the 2014 manager of the year, leading the Washington Nationals to a 96-66 record and a playoff berth.
On Monday, he was fired. The contracts of all seven coaches were also not renwed.
The dream season of 2014 turned into a nightmare 2015, as the Nationals were by acclamation the biggest underachievers in baseball.
Widely predicted to win their division, or even the World Series, the team led by four and a half games at one point, but collapsed to finish 83-79. Bryce Harper had an M.V.P.-type season, and starter Max Scherzer had another fine year, with two no-hitters, but most of the rest of the team underperformed.
