The weight of the bat, inside pitch, swinging to early, arms not extended, all could be factors, how are the middle to outside pitches, pulling those or going with the ball, I went up in weight with full overlap this winter and had to go back to 27’s with it, more comfortable and controllable, since the overlap is new and you have been doing a lot of tee work vs live it takes time, you really probably need more bp with live pitches, grab a cheap bat and go to a batting cage just to work on timing, arm angle. For me i Have long arms and I use overlap with a drop pinkie, so that moves the bat out farther, I won’t hit inside pitches unless I have too and I tend to hit them way out in front after my wrist has started to roll and it creates a ground ball to third, if I try to wait and get more barrel, I end up pulling my hands in and hit a weak ball to left side, so I try to stay away, otherwise if they keep pitching me that way I go to a standard almost choke up grip to compensate for more barrel
