The skill that gets paid is (shape + location) Assuming you get by on stuff+ alone is fortunate ignorance.
The moment you think your command will suffer because you’re learning a new pitch you’ve already lost.

Having nasty stuff and only locating the zone puts your fate in the odds (which usually are decent it seems.) However, consistent success, not on accident, always will require throwing the shape you intend to the location you intend.

Yeah so command is correlated to RA9 - xERA but stuff isn't This is the most absurd result I've ever seen

We just disagree with the definition you’ve settled on
Based on comments, and my expectation, folks: (a) have no idea a swing has not ever been defined before ACS (automated-checked-swing) (b) and believe in any case the side-angle view of plate crossing must be defacto standard (based totally on being hammered that non-fact by TV)

Pitch maxxing in 2026 and beyond It’s compound interest, in that you can throw to the zone reliably.
Replying to @Kaminsky21
It’s always better to have another pitch if you can throw it for strikes.

Also the process of refining your ability to manipulate the ball.. is probably is a useful endeavor if you want to be good at the sport in the long term. Learning new pitches can give you better calibration (zone location, and pitch shape consistency) if approach it right.

My current belief is you should perform constraint drills as if you are not doing a drill at all. but as if it were a competition. “Hey you got a drill for that?” Yeah, but it won’t fix the problem you have. Cheesy, but you have to have one mode - compete mode.

Notice how when you view pitches from weird outlier angles it’s hard to tell which way it’s moving? Hmm…. 🤔 (Tweet 3 and 4 are where the good stuff is)

When you view a pitch from a side angle like above , both pitches start on the right of the frame and move to the left. Despite one being a cutter and one being a two seam.

Stress is a meal that I feast on. I pull down sweepers and cutters specifically to resilience max my arm. Two sides to every coin.
Orel Hershiser on analytics culture & pitching. Pitching labs have created obsession w/tweaking pitch grips for "optimum" movement. Practicing this at max effort, w/many different grips, puts considerable strain on the arm. #shegone #Dodgers @OrelHershiser

Guys, this is what you need to know. You HAVE to throw pitches in the zone consistently ASAP. Your velo will go up if you persist with good means. You will develop better feel for spin year after year if you try, but only if you play long enough.
College: 4.4 BB/9 🥲 👇 Proball: 2.3 BB/9 ✅ I literally cut my walk rate in half by understanding this one aspect… Not by fixing my mechanics. Not by throwing harder. Not by perfecting my shapes. But through understanding movement processing.

Going to be releasing a E-Book “Command Training principles and Applied Methods” soon. This will walk you through how I came to view and understand, movement processing (MP) and how it contributed to better command.

The best part about ABS Is the called K-zone is going to be the traditional one, ALL GAME. UNLESS, someone challenges.. then we’ll confer to the zone that is 8.5” back. I just want continuity

PSA: If you can throw a Curveball at the top of the zone with ABS… The zone is 4” higher. (or more depending on iVB )
Replying to @avondisse
In MLB 2025, fastballs fell 0.79" between the front and middle of the plate, compared to 1.25" on all non-fastballs. So by moving the zone back, the zone effectively moves up. And the top of the effective zone was about 4" higher for breaking balls than fastballs.

So is the arm side sweeper is able to be a ABS strike but actually be 2+ inches outside of front plane of the plate? Does that mean my glove side sweeper needs to be 2”+ inside the zone to cross on the horizontal edge of the zone? Can of worms.

After having pitched at a field with just as egregious dimensions, it’s extremely beneficial. You have to buy into process. Sinker that a righty hits 305ft for a HR? Literally psychological therapy to remove the emotional response from the action. Did I hit my spot? Great

Thought this was modeling observed and inferred spin direction lol
I'm trying to figure out where to live next, and one big consideration is the climate. So naturally I made a tool that represents monthly average temperatures for cities as 3D rings so they can be compared more easily. Check it out: awjuliani.github.io/weather-…

It runs like it just finished it’s 5th 300yd shuttle
At this point, in dont get it anymore. Yes, it looks impressive. But whats the use-case other than proving that, well, it can get up fast and run?

Can’t wait to get this paired with pitch approach angles. 👀
In a single visual it's possible to get a decent grasp on how a hitter's bat enters the zone, how well they release the barrel, and their barrel direction at contact. What else do you notice here?

The most efficient player development is always athlete education. I wonder what the game would look like if teams offered continual ed to everyone who’s willing to learn..

Insert kick change:
I was primarily a 2 pitch mix; mainly sweeper, for several years. This year (year 7) I brought 6 pitch types into the season. You never know what stacking up days of reps can do for you in the background, especially on other pitches like @drivelinekyle is saying

Guys, if you think the zone being ambiguous is weird just wait till you learn they pushed it back to the middle of the plate instead of the front plane.

If you saw the bat pointing to the right-fielder would you call it an attempt at a swing? Poll in replies
Major League Baseball will begin experimenting with using bat-tracking technology to call check swings starting tonight in the Single-A Florida State League. More details: atmlb.com/4k7hsj3
