Thanks for the good information. From what I hear a batter called out for batters interference on a 2-1 pitch should be a putout catcher, not a strikeout as was recorded.
Incidentally this past weekend, I saw a runner's interference and a fielder's interference in same game. A third call in game to last batter had major impact. Batter hit with a pitch in ankle was summoned back into the box as he was said to have not made an attempt to get out of the way. Next pitch was a walk-off HR.
