Eating Crow: xBABIP and the Shift
A few days ago, I looked at the effects the shift may be having on players using the difference between their BABIP and xBABIP. The observed drop in a player’s BABIP, compared to their xBABIP, was 41 points. As reader phoenix2042 pointed out, I was using a dated formula for xBABIP. By using an updated xBABIP formula, I still found a difference, but not as much of one.
