Interesting. This from the first BP article is encouraging:
Doumit dropped his head on 11 of the 12 pitches I reviewed on video. On the one pitch where he did not do that, he got a strike call. Molina dropped his head to follow the ball into the glove on two of the 10 pitches I reviewed on video, and both of those pitches were called balls.
Lucroy’s head was stable on all seven pitches I reviewed, and he got seven strike calls. Varitek’s head was stable on all six pitches I reviewed, all called balls, but his exaggerated glove movement may have cost him those strike calls.
It would seem there are some simple things Doumit could do to improve.
Most sensible comment in the discussion.
If it is a skill, it can be improved. The Twins have access to all of the video and corresponding data. It probably is available sorted by call, pitch type, location...
Do it for all of the catchers.
If the Twins do the leg work on this, there is no reason it can't improve as long as there is awareness.
