Here's another way of looking at it:
This breaks down batting averages in for ground balls and line drives, both overall and by handedness. The row at the top is 2023, with the shift ban in effect.
So far, the results show increases in batting averages in all situations to varying degrees this season versus last, although this compares this year's partial seasons to last year's full season. It being only early May, it remains to be seen whether teams are going to moderate their positioning to become more shift-oriented than they have been so far. For example, speaking just anecdotally, I seem to be noticing more shortstops positioning themselves right up to the imaginary second-base middle line for LHH—basically, playing right up the middle—whereas earlier this season I thought they had been shaded more toward the traditional shortstop position. But this is just one guy talking more or less out of his ear—surely someone has positioning data they will be looking at and reporting on at some point during this season. But point is, these 2023 figures may change as teams presumably become smarter on how to position themselves vis a vis the new rule.
