Over the last few years, the use of The Shift Defense has increased dramatically in baseball. Here are the Major League Baseball totals of the number of shifts in baseball, as tracked by Baseball Info Solutions (BIS).

For many years now, most teams have employed The Shift, but only against a handful of players (David Ortiz, Ryan Howard, Adam Dunn, Jim Thome, etc.). Research done by BIS in recent years has shown there are as many as 100 batters against whom The Shift is likely to be effective. More and more teams are now shifting on more and more different players. Here are the teams shifting the most this year:

Overall, BIS estimates that teams have saved themselves 89 runs by using The Shift this season.

But even as often as these teams are shifting, they are still not shifting against anywhere near the 100 players suggested by Baseball Info Solutions. The most aggressive (and progressive) teams are now up to about 30 different players against whom they use The Shift Defense. We believe that there is still room for even better results by shifting against as many as 100 different players in MLB.
