Another postseason collapse has cost Dusty Baker his job.

The Washington Nationals have announced that Baker will not return as manager next season, after two years at the helm, two NL East titles, and two bitter first-round playoff exits.

Baker led the Nats to their first back-to-back division titles in franchise history.

​​The Marty Schottenheimer of Major League Baseball, Baker has shown that he's possibly the best regular season manager in the game -- but playoff baseball is his kryptonite.

Washington was Baker's fourth stop as a manager in the majors, and every one has been marred by playoff disappointments. There was the World Series collapse with the Giants in 2002, the Cubs' NLCS disaster of 2003, and three first-round playoff exits in four years with the Cincinnati Reds. Now, it's two NLDS Game 5 losses in a row that's cooked it for Baker's Nationals tenure.

At 68 years old, one has to wonder whether Baker is ever destined for another MLB job.  

One thing's for certain: the Nationals are tired of playoff disappointments. As a result, they're looking for a new manager once again.
