We’ve seen, heard and read a lot about the extreme defensive shifts being used across the league this season, and witnessed its effectiveness first hand as batting average for balls in play has continued to decline from what were the previous standards.┬áMoving fielders into positions where the ball is most likely to travel with certain hitters at the plate seems like such an obvious thing to do, and yet it simply wasn’t being practiced to the extent that is now.

Over the weekend, Getting Blanked’s Travis Reitsma wrote about how defensive shifts have specifically helped the Toronto Blue Jays in the early going and today, John Lott of the National Post goes into even further detail on how a more active defense has increased the team’s win total and made defensive stars out of its infield.

The most often quoted defensive metric when accounting for defensive shifts is Defensive Runs Saved, which has a complicated formula, but in a quick and dirty sense, can be understood by calculating that if a player makes a play that 25% of players at his position make, he scores 0.75, and if he doesn’t make a play that 25% of the players at his position makes, he loses 0.25 from his cumulative score.

Under these guidelines, the Blue Jays are currently employing three leaders at their position in the team’s infield. This, is due in large part to Kelly Johnson, Yunel Escobar and Brett Lawrie being positioned in places on the diamond that aren’t typically covered by players of their positional designation.

While more and more attention is being given to active defenses from around the league, what isn’t being talked about as much are the improved analytics going beyond mere spray charts that are informing coaches and players of the tendencies of certain batters. In this sense, I think fielding is the first step to a more wide spread acceptance toward how data can assist in actual decisions being made in the dugout.

It seems to me that while front offices have entrenched themselves strongly in analytics for the purpose of player acquisition, there’s been a disconnect between that thinking and the traditional decisions being made in the dugout. I wonder if the effectiveness of fielding shifts might open up coaches and managers to a more percentage based mode of thinking when it comes to bullpen management, pinch hitting and defensive substitutions.

It’s really only a matter of time until we see that first manager sitting on the bench with an arm firmly clenched around his iPad.
