Pictures don't tell the whole story...
Left picture only gives where (4) crossed, but could that have been a CB that broke late and was letter high before break? IOW, it could have looked like (1).
Right picture has (1) being a called strike and leads to other pitches in that area. Coming inside with (4) and not getting it is a shame especially since (3) was expected out of zone on 0-2 count. Was the batter crowding the plate since he's had pitches on outer third... was the catcher set up way inside causing a partial block of view. Was the catcher set up outside and the pitch came inside? Was that pitch caught by the catcher? I assume R on L here considering your nick, but L on L w/ (4) could be a tough call with batter crowding plate and catcher set up inside. That low inside is one of those mental pitches you have to get and if you've been calling 1-2 balls off the plate outside, then it's even harder mentally at times to grab [too far] inside.
