I was curious about which MLB teams changed their fortunes the most this season compared to last year, so I crunched the numbers.
First, here are the biggest win total improvements from 2014 to 2015:
+10 Blue Jays
The top five teams on the biggest-improvement list all had managers in their first season on the job, led by Joe Maddon joining the Cubs after tons of success with the Rays. Also worth noting: Of the nine teams with the biggest win total improvement, seven made the playoffs. Only the Twins and Diamondbacks improved to double-digit games and still failed to make the playoffs.
Now, here are the biggest win total declines from 2014 to 2015:
Not surprisingly, a whole lot of those teams have changed managers, general managers, or both. And a couple more may still do so before the offseason gets underway. Oakland retained manager Bob Melvin despite an MLB-high 20-win dropoff and just promoted Billy Beane from general manager to vice president of baseball operations.
