Another good twitter feed to read

Not as good as Pitching Ninja (yet) but interesting for sure.  It's from the head of MLB Baseball R&D.  Lots of Astros info in the feed from yesterday.  Statcast-generated views of things.  I especially like to see the field positioning diagrams as plays (like a rundown) develops.

Very cool! I didn't understand the positioning one, though.

Very cool! I didn't understand the positioning one, though.

For example, here's a flyout to Springer.  Each position starting point is the small circle and the big circle is the player position when the play ended.  In this example, Springer moves like a foot since he is so well positioned and the center fielder instinctually moves a few steps to right to cover.  Red line is the path of the ball.

In this scenario, it's a rundown so the player positioning over time is much more complex with the left fielder covering third base and the center fielder sprinting in to back up the rundown.

Just eyeballing it, it looks like he had about the same number of 0-2 and 1-0 counts.  Awesome.

Yes.  That diagram is heavily weighted to the 'pitcher's count' side.
