UZR Question

+1 vote
UZR is excluded from plays where the shift is put on, but how accurate is the recording of these shifts? At what point do you call a defensive alignment a "shift"? It seems that if this shift is not "seen" by the BIS stringers, a player can be out of position to get balls that would normally be in his range, which would kill his UZR.

So you're looking for an arbitrary cut off point that defines a shift? E.g. 10 feet to the left isn't a shift, but 11 feet is?

If so, good question. I'll try and draw more attention to this.

Baseball Info Solutions records shifts when the defensive alignment affects the outcome of the play:

"For example, if the third baseman is shifted over to where the SS plays and a ball is hit anywhere in the vicinity of where the third baseman would normally play and it results in a hit, that's a shift.

Similarly, if a fielder is shifted into what would normally be a hole and a play is made by that fielder that wouldn't normally be made by any fielder OR a play is made by a fielder playing out of position (like your example), that's also a shift. "
