Heat zones

Cool graph on where pitches go in the strike zone.

Wonderful presentation!
What I think would be very useful is the use of 2x2 tables for called strike/ball and hit/bip out, by handedness of batter and pitcher, of course.
For example:
+---------------+---------------+
| called strike | ball |
|---------------+---------------+
| ball | called strike |
+---------------+---------------+
and
+---------------+---------------+
| bip hit | bip out |
|---------------+---------------+
| bip out | bip hit |
+---------------+---------------+
This would alway easy comparison of pitches left/right and up/down.

Tango,
What perspective are the images you linked to shown from? Is it the pitcher or catcher’s view? I assume the units on the axes are in feet; is that correct?
I asked Jonathan that very question, and his reply:
The perspective is from the catcher. And L/R is lefty pitcher right batter.
He’s also writing an article for THT, as well as breaking out the graphs BY COUNT, where we’ll see different heat zones (even strike zones) based on the count. Stay tuned for that…
Man, I love all these guys working on PITCHf/x.

Here they are, courtesy of Jonathan, by count. Start with the 0-2 and 3-0 counts, he most obvious counts where a pitcher will either avoid the middle, or only focus on the middle.
I find these charts so very cool:

SirKodiak had a neat idea to put all the charts on one page, so he provided the page, so here you go:

Cool work by Joe Sheehan:

He also announced that he’s interning with an MLB team. Good for him, as he deserves it.
Dan Brooks has his cool heatzone charts. But, in this case, it’s based on whether the batter SWUNG at a pitch (regardless of outcome).

So, this is a great thing to compare to Hale’s charts. Hale tells you where he throws a pitch. Brooks tells you when he swings for a pitch. All that you need is to know when an umpire calls a pitch as ball or strike (as Walsh did last year), but by count, and you can now model a batter/pitcher matchup as a Markov chain.
Beautiful. THIS is what baseball is about.
Dan gives us the hitter’s heat zones for all counts:

(I think the 3-0 is inverted, though it may be corrected by the time you read this.)

More breakdown, this time by handedness of batter and pitcher:

Makes alot more sense.
