Here it is. The two red dots are the first two pitches of the at-bat and both were called strikes. He ended up walking.

Well, lookie there. Right in the strike zone.

Looks like Reed did good job and Larry did what he's most famous for.

nice posts jim...the gameday feature is nice.

The bottom of the strike zone seems kinda high to me.

The STRIKE ZONE is that area over home plate the upper limit of which is a horizontal line at the midpoint between the top of the shoulders and the top of the uniform pants, and the lower level is a line at the hollow beneath the knee cap. The Strike Zone shall be determined from the batter's stance as the batter is prepared to swing at a pitched ball.

The bottom of the zone on the gameday screen appears to be at the top of the knees.

Just checking, and meaning no insult...you do know the difference between "beneath" the knee and "below" the knee...right?

No insult taken. I read the definition of the zone as the bottom being the soft soft (or hollow) just south (toward the feet) of the knee cap. Is this not how you interp?

Nope. "Beneath" in this case could kind of be replaced with "behind" if you use the cap as the knee.

I should have clarified this -- the virtual batter you see is not accurate. That virtual batter is the same for everybody, except he's on the right side for a right-handed hitter. The strike zone is not properly aligned with the virtual batter. The relationship between the strike zone and each pitch is accurate for each batter, it is just that virtual batter that's not accurate. It is a work in progress, and maybe the virtual batters will be better next year -- but they are just there for show.

I wish I could say more about the sizing of the strike zone, but I've signed a confidentiality agreement and that information is not something I can share.

Oh yeah, and I was promoted to Tech Support a couple of weeks ago, so I'm not just an operator anymore. Now I supervise and assist operators at all venues across MLB when I'm not working at Chase Field.

and the lower level is a line at the hollow beneath the knee cap.


So that is just another way of saying" The centerline of the kneecap". Right?

That's a phrase that could use some cleaning up.

Jim,

You state the accuracy is within 2/10ths of an inch.

I have never seen an inch broken down into 10ths before. Are you stating that the accuracy is between 3/16ths and 1/4 of an inch?

Guess you don't work in manufacturing or engineering.

I was just writing out the decimal point number. My best error reading so far has been .18", or a little less than .20" = 2/10ths or 1/5th of an inch.

And your interpretation of this is based on what? How do you get "behind" as being what was intended? Why wouldn't they just say "behind the knee" if that's what they were trying to get at?

Last I checked my patella (which was just now), the hollow of the knee is directly below my kneecap, on the front of my leg, not the backside of it.

From my limited understanding, when they changed the bottom of the strike zone from "top of the knee" to "the hollow beneath the kneecap," it was to make the strike zone bigger. If you look at the diagram in the rule book, the dotted line representing the bottom of the zone intersects the hollow directly beneath the front side of the knee. That line is significantly lower (perhaps an inch or so) than the crease that is "behind" the knee.
