I watched every 3-2 take by Bryce Harper in 2025. Here’s what it revealed:
1️⃣ Yes, Yes, No Approach - he is swinging until the ball tells him “no”. His barrel starts to turn on almost 100% of his takes. You will see these type of “active takes” with pretty much every high level hitter
2️⃣ He Can Stop Late - because his barrel turns rearward and creates depth, it allows him shut down or abort his swing as late as possible. This gives him a longer time to identify pitch speed, shape, and location

This is the textbook I wrote to support the most advanced high school math/CS sequence in the USA.
It's freely available. Link in first reply.
In Math Academy's (former) Eurisko program, which ran from 2020-23, we scaffolded high school students up to doing masters/PhD-level coursework: reproducing academic research papers in artificial intelligence, building everything from scratch in Python.
We currently have all of Eurisko's math prerequisites available on the Math Academy system (which is where Matteo and other Eurisko students learned it).
Eurisko ended in 2023 when I relocated because nobody else in the district had the requisite knowledge to teach it.
But we will eventually have the entire Eurisko curriculum, and more, on the Math Academy system.

Can't think of a better way to close out 2025 than seeing the head of NASA ask my former student @matteopaz06 to apply, with a fighter jet ride as a signing bonus.
Matteo was one of my students in the Eurisko program, which, during its operation from 2020-23, was the most advanced high school math/CS sequence in the USA.
It culminated in high school students doing masters/PhD-level coursework (reproducing academic research papers in artificial intelligence, building everything from scratch in Python)
Matteo joined Eurisko as a 10th grader, during the last year it was offered, and worked hard to complete almost all 2-3 years’ worth of assignments in a single year. (Eurisko ended when I relocated; nobody else in the district had the requisite knowledge to teach it.)
This is exactly the position that we were trying to put students in with the Eurisko program – get them to a point of skill that they can capitalize on some math/coding-related opportunity and turn it into a chain reaction of fortunate events. And it’s been so great to witness some of these chain reactions get underway.

Listen to Darryl Strawberry talking about not dropping your back shoulder and using your hands.
“Straw” could hit a baseball as far as anyone!

If you’re teaching hitters to stay heavy on the backside, you’re flat-out ruining their sequence.
You’re locking up the exact thing that creates real rotation.
The rear leg HAS to release.
If it’s stuck, the back hip will NEVER snap into the front hip.
No hip collision = no power, no adjustability, no shot against real pitching.
Staying “backside heavy” freezes the pelvis, kills ground-force transfer, and forces the barrel to dump or push.
That’s amateur-hour coaching.
You can’t snap the back hip into the front hip if the rear leg is cemented in the ground.
You can’t release the front foot without hip collision.
You can’t rotate around center mass if you’re sitting behind it like a statue.
This is basic human movement:
•Rear leg releases → hips collide
•Hips collide → torso turns
•Torso turns → barrel follows
Lock the rear leg?
You break ALL of it.
So stop teaching hitters to camp out on their back leg.
You’re not creating power you’re creating stuck, late, unadjustable hitters who will get exposed the second velocity and movement show up.

The Pelvis and Deep Core escort the Arms!
Think of it like a spinning top: The pelvis and deep core are the base —get them right, and the arm Flow effortlessly.
And remember: the faster you turn and stop the middle, the more Speed and Flow you create up top

Forward bend (hinge) should turn directly into side bend (tilt). This keeps the chest over the plate and your eyes behind the ball - allowing hitters to maintain barrel direction through the middle of the field.
Try it out.

“Ways to build accuracy and bat to ball skills? Hold your finish with your head down. Exaggerating the hold of your finish teaches your body how to be connected properly. Doesn’t allow over swinging and spinning off the ball. Do less to do more.” @xenpennyhitting one of the best processes for me, keeping it simple with huge results! @XenPenny @michaeltardio

As for the rearward tilt,
does Javy Baez tilt here? Does I use a hip coil?
