As you can see below, some teams, like the Red Sox, Orioles and Mets, that were bottom-feeders in the Spring made the postseason.
The Cubs sucked in spring training, but won it all eight months later.
On the other hand, nobody had a better spring record than the Washington Nationals last year. The Nationals made the playoffs but lost the divisional series to the Dodgers.
The Dodgers didn’t have a great spring, but made it all the way to the League Championship Series before losing to the eventual World Series Champion, Cubs.
