Here’s the thing about bunting: it can be a good idea if the third baseman is playing too far back. The chance of a hit goes up in that case, and a successful bunt often causes the third baseman to play more shallow in future plate appearances, so future balls in play receive a benefit. That’s one of those games within a game we see all the time in baseball: once the positioning deviates from “normal” by a certain degree, the batter receives a benefit. Then the defender has to change his approach.
This tension created by the bunt illustrates how offenses and defenses react to each other’s tendencies. That same sort of balance between fielder and hitter might be playing out on an even broader scale, however, when it comes to the shift in general.
Too many shifts in the game, and the players begin to adjust. They develop more of a two-strike approach, they find a way to put the ball in play on the ground the other way, or they make sure that they lift the ball if they’re going to pull it. There’s evidence that players are already working on lifting the ball more as a group, pulling the ball in the air more often than they have in five years, and have improved on hitting opposite-field ground balls. So maybe this next table is no surprise.

The league has improved against the shift! The shift is dead! Or, wait: the league has actually improved as a whole over this timeframe, and the difference between the two is still about the same. And every team would take a .292 wOBA against over a .297 number. Long live the shift.
