back of vertical elbow faces the plate = Lat on fire
We have six questions:
1. When their pitching forearm is horizontally behind their pitching elbow (Maximum Pitching Forearm Acceleration Position), does their pitching upper arm face toward home plate?
2. In their Maximum Pitching Forearm Acceleration Position, does their pitching elbow stop moving forward?
3. From their Maximum Pitching Forearm Acceleration Position to Release, does their Triceps Brachii muscle vertically extend their pitching elbow?
4. Immediately after they release their pitches, does their pitching elbow point upward?
5. When their pitching forearm horizontally points toward home plate, is the palm of their pitching hand facing upward?
6. At the end of the deceleration phase, do baseball pitchers stick their pitching hand into the strike zone, such that their pitching arm does not cross the midline of their body?
It helps to have high speed film from the front and pitching arm side views to determine precisely if baseball pitchers engage their Latissimus Dorsi muscle.
This will dramatically increase release velocity but unfortunately also dramatically decrease pitching arm injuries.
So we will have to wait for a foreign tool to reword this into scientific gobbledygook so the dads of #BBTrumpland will buy in. 2-4 years tops.
Stay tuned
How many pitchers on the @Brewers or @RaysBaseball will train today?
Rest is the enemy.
I’m sure Israel-first @BillAxkman has no problem with Israelis beating up American citizens.
And the dads of #BBTrumpland will go along.
Because they think what they are told to think.
But where’s @elonmusk ?
I hope someone out there cares a little about the young men in Texas.
Not looking good
And don’t forget, Clayton Kershaw has committed to bringing the work of ASMI’s bestest earner. Tom House, back home to Texas.
I call it #BBTrumpland
Is there any other guru that posts such instructive videos?!
Pitch types is nice but the functional rotational force of the body is more interesting (to me).
The gurus tell the dads of #BBTrumpland to forget about the arm. It’s all about the rotation of the hips and shoulders separately.
I’m obviously not a guru.
Let’s take a look at what hip and shoulder separation does for these guys.
All 4 pitchers leave their pitching leg near the rubber as all pitchers do when they separate their hips from their shoulders.
With Coach Newton in mind, how far do these pitchers rotate toward home plate at ball release
If you draw a line through the acetabula lines of each pitcher you will clearly see that each pitcher rotates his hips short of perpendicular to their driveline to home plate. This is because they can get their pitching foot very far off the rubber.
The functional range of motion for baseball pitchers is 180°. Therefore to apply force toward home plate for as long and as close toward home plate as Coach Newton requires, Dr Pourciau’s pitchers would have to rotate their Acromial lines 180°.
We can see that each pitcher rotates his Acromial lines only 90°, leaving 90° unused.

I hope the dads of #BBTrumpland understand why PTBoddy loves the elbow spiral. I fount the scientifically challenged @RedSox did.
It seems like 100 years ago that Dr Mike Marshall warned Tom House about the Fast Arm Tom imported from Japan. Tom renamed it Double Spin.
It proved so successful at injuring pitchers that PTBoddy brought it back under the name…Elbow Spiral.

The dads of #BBTrumpland should consider our 13-14 yo girls when they cast their ballot.
This 1966 photograph shows Danny Thomas with his wife Rose Marie and their children Marlo, Terre, and Tony. It looks like an ordinary family portrait. It is also the visible result of a promise made when he had almost nothing.
In 1937 Thomas was a struggling entertainer in Detroit. His wife had just given birth to their first child, Marlo, and he could not pay the hospital bill.
Walking the streets one cold November night, nearly broke and ashamed, he stepped into a church and put his last seven dollars into the poor box. Then he prayed to St. Jude Thaddeus, the patron saint of hopeless causes: show him the way, and he would build a shrine.
The next day he landed a job that paid ten times what he had given. It did not make him rich, but it kept his family afloat. It also convinced him that a promise made in desperation still mattered.
As his career grew through radio, film, and television, he never forgot it. When the time came to repay the vow, he did not build a statue. He built a hospital.
On February 4, 1962, St. Jude Children’s Research Hospital opened in Memphis. It was the first fully integrated children’s hospital in the American South.
Thomas set one non-negotiable rule: no family would ever receive a bill—for treatment, travel, housing, or food. Parents had only one job: helping their child survive. At the time, childhood cancer survival rates hovered around 20 percent.
Betting everything on children most people believed could not be saved looked reckless. He bet anyway.
Rose Marie stood beside him through it all. Together they once traveled to 28 cities in 32 days, fundraising nonstop. It was not celebrity charity; it was gratitude turned into long-term work.
The results changed medicine. Today survival rates at St. Jude exceed 80 percent, and the hospital shares its research worldwide so children everywhere can benefit, not only those who can pay.
The children in the photograph carried the promise forward. Marlo Thomas became an actress and activist, a Presidential Medal of Freedom recipient, and the founder of St. Jude’s Thanks & Giving campaign.
Tony Thomas became one of television’s most successful producers and serves on the hospital’s board. Terre Thomas has supported ALSAC, St. Jude’s fundraising arm, for decades.
Danny Thomas died in 1991, two days after marking the hospital’s 29th anniversary with patients and families. He was buried on the grounds beside the shrine he had promised.
Rose Marie joined him there in 2000. Their children are still keeping the promise.
At the hospital’s dedication Thomas once said that if he were to die that minute, he would know why he was born.
The dads of #BBTrumpland aren’t going to blame Dear Leader for the mess we are in
Israel-first @BillAckman ‘s silence on Iran speaks volumes. But the damage is done.
I’m sure I’m not the only one that has noted @elonmusk ‘s refusal to endorse Bill’s bloodlust.
Elon played this like a champ.
He and his fellow Brits are going to enjoy watching Israel get slammed.
Thanks Bill
Velocity is king.
What does my foreign tool Isaac Newton have to say?
Vr=FxT/M
V = velocity of bb at release
F = Force applied to bb
T = Time force is applied (.20)
M = Mass of bb or .01 (rounded)
If Eric Orze can pitch a baseball 94 mph with the current stats of M (.01) and V (94 mph = 137.9 ft/sec). And T =.2. We see….
137.9 = F x .20/.01
137.9 x .01 = F x .20
1.379 =F x .20
1.379/.20 =F
F = 6.9 lbs (approx)
Once gurus know the force they can discuss mathematically how to increase release velocity. There are two ways…..T and/or F.
If Mr Orze applied that same amount of uniform force (6.9 lbs) for 1/100th of a second longer toward home plate he’d achieve a release velocity of
V = 6.9 x .21/.01
V= 98.8 MPH
Where can Eric Orze find 1/100th of a second or extra time of force being applied?
My readers should be able to explain a grab (and Tom House’s role)
And only Two people on X can fix it. And I’m not saying.
Be nice to Lon
And best wishes to Eric Orze

When baseball pitchers are forced to separate their hip from shoulder rotation, guess what muscle gets eliminated from the velocity discussion.
They never listen
I posted years ago about how to use the Acumobility Ball for upper extremity health and performance, so it seems long overdue for me to share one of the ways we’re using it a bit further down the chain: on quadratus lumborum: ericcressey.com/exercise-of-…
Dr Brent Pourciau writes
“When adolescent pitchers who needed shoulder or elbow surgery were compared with healthy pitchers, the strongest links to injury were overuse and fatigue (Olsen et al., American Journal of Sports Medicine, 2006).”
Hey Skippy, are you tired.
Yeah coach, I’ve pitched two innings and bushed. Talk about neutered.
Someone should asked Brent how he determines fatigue. Nobody will, but they should.
Overuse is another story. Parents should be very wary of Skippy pitching too long , too hard and too often. I recommend any part of two inning until pitchers are 14 years old.
Dr Brent continues.
“Velocity isn't the enemy. How you chase it is.”
I agree. Parents sticking their kids in weight rooms should be very cautious. The growth plates of young pitchers need a break. That is why we should be recommending a wide variety of sports.
If Skipster wants to lift weights I recommend my 60 Day Skill Acquisition program.
Otherwise I’d focus on technique. I would think Dr Pourciau’s facility would be a good place to lift weights correctly.
Two pitchers. Both chasing 90. Only one still throws at 18. ⚾
One built his body first: strength, speed, two seasons, real rest.
The other chased the radar gun 12 months a year, with max effort and no foundation.
This isn't a scare story. It's what the research shows:
📊 Pitchers who threw more than 100 innings in a year were 3.5X more likely to suffer a serious arm injury (Fleisig et al., American Journal of Sports Medicine, 2011, a 10-year study of 481 youth pitchers).
📊 When adolescent pitchers who needed shoulder or elbow surgery were compared with healthy pitchers, the strongest links to injury were overuse and fatigue (Olsen et al., American Journal of Sports Medicine, 2006).
Velocity isn't the enemy. How you chase it is.
Build the engine (legs, trunk, strength, mechanics) and the arm doesn't have to do it alone.

As a PhD Brent Pourciau wants desperately to do well. But that little thing called science and modernity gets in the way.
Brent wrote:
“Pause your pitcher's video at foot strike. Look at his chest. “
When a pitchers glove foot lands, my foreign followers should look for the baseball. If the palm holding the baseball is facing down and the baseball is not in my Ready position we have Late Pitching Forearm Turnover. Late Pitching Forearm Turnover helped Dr James Andrews leave ASMI with 100 milly of the dads of #BBTrumpland hard earned cash.
But Brent focuses on the negative. He looks at the chest
Brent continues:
“If it's already turned to home plate, his hips and trunk opened together. The stretch that whips the arm is gone,”
I’ve asked a dad from #BBTrumpland to show a little interest in young Skippy and ask Dr Pourciau to explain what muscles are causing this ‘stretch’. A PHD should know. Brent knows no dad cares enough about his son to ask.
Brent goes on to praise hip-shoulder separation:
“Hard throwers look different: front foot down, hips open, chest still closed.
The research backs it up.”
The ‘research’ backs up hip/shoulder separation. Hip/shoulder separation leads to more velocity (sic).
Yet a few weeks ago, Brent told the hapless dads of #BBTrumpland hip/shoulder is not a teach. Fancy that
I teach pitchers to rotate their hips and shoulders forward together over their front foot.
I prefer velocity to injury.
You’ll be seeing Brent and his fellow travelers start talking about pitchers getting over their front leg. Why? Because the dads may not have noticed but the gurus noted me saying to look at the pitching leg at release ……acting like an anchor.
Stay tuned.
Pause your pitcher's video at foot strike. Look at his chest.
If it's already turned to home plate, his hips and trunk opened together. The stretch that whips the arm is gone, and that's velocity he's leaving on the mound.
Hard throwers look different: front foot down, hips open, chest still closed.
The research backs it up. Professional pitchers rotated the trunk significantly later than college, high school and youth pitchers. Among skeletally mature pitchers, they also had the lowest shoulder rotational torque (Aguinaldo, Buttermore & Chambers, Journal of Applied Biomechanics, 2007).
Try it tonight: film from the side, pause at foot strike, check the chest.

Bad for bidness
This infomercial from Eric Cressey has no relevance to pitching so I have no comment.
It looks like @StrengthDebates ode to low reps sets is catching on.
Just as a reminder, in my world of baseball pitching we overload with a minimum of 24 reps and maximum of 48 reps.
Baseball pitchers have to be strong.
Whenever someone talks about a plateau in a training program, they usually ask is “What should I do?” In reality, the answer isn’t just what one should do, but what one shouldn’t do, as well. ericcressey.com/strength-tra…
4 of the grips are incorrect.
No biggie
Who threw the nastiest pitch in baseball this year? We ranked every pitch type by 2026 Statcast pitch value. 🧬⚾
4-Seam: Jacob Misiorowski
Slider: Dylan Cease
Curveball: Braxton Ashcraft
Changeup: Walbert Ureña
Splitter: David Bednar
Sinker: Nolan McLean
Cutter: Sandy Alcantara
Swipe for the grip (demonstrated by former MLB pitcher David Aardsma), the velocity, spin, movement and whiff rate of each one compared with the MLB average.
Then look at the last slide. 6 of the 7 threw their pitch harder than the league average for that pitch, by an average of 2.7 mph. Movement matters. Velocity makes every pitch better.

Dr Brent Pourciau writes
“The goal is to load the back leg as you move, instead of treating the drop and drive as separate actions.”
I suppose the hapless dads of #BBTrumpland don’t mind turning their 6ft tall sons into 5 foot tall pitchers.
And why the heck not?
Here’s why….
Proprioceptively, loading that rear leg into the ground and pushing powerfully off the mound sideways seems like a good idea. Dare I say, it’s very Japanese (Translation). And we know the dads of #BBTrumpland love all things not American.
The problem is the Brit, Coach Isaac Newton. The baseball is not directed at home plate while all this powerful striding is going on. I prefer using our powerful muscles to direct the baseball toward home plate.
I guess Skippy might feel more comfortable being neutered pitching like he’s 5ft tall.
SINKING ISN’T DRIVING. ⚾
Watch the first move—not just the arm.
❌ Going down without moving toward the plate.
❌ Reaching forward without the loading cue.
✅ Lowering while the hips move forward.
Our cue: DOWN + FORWARD. TOGETHER.
The goal is to load the back leg as you move, instead of treating the drop and drive as separate actions.
Watch the MechanicsDNA examples: first, the X shows drop-then-drive. Then the check shows down and forward together. Follow the hips through both deliveries.
Treat this as a coaching cue—not a fixed inch-for-inch rule for every pitcher.

I’m surprised the nominally Christian dads of #BBTrumpland don’t thank Dr Brent Pourciau for posting these videos. They are very instructive.
Brent correctly advices the sons of the dads of #BBTrumpland to rotate late.
Like most gurus, Brent’s doesn’t quite understand what I mean when I say pitchers have to rotate late. It is because I prefer velocity over injuries.
I picture below Brent at his demonstration of good late rotation at the end of his video.
Brent believes hip/shoulder separation is a good idea. Yes, you injure the Oblique Internus Abdominis muscle, but using fewer muscles reduces velocity.
If you separate the hip from shoulder rotation, it is impossible to rotate late. To rotate late as I recommend, baseball pitchers have to forwardly rotate over their front leg BEFORE they release the baseball.
Even the dads of #BBTrumpland should be able to see how much closer pitchers can release their pitchers to home plate by rotating over the front foot.
They clearly prefer injury to velocity.
Brent Pourciau clearly knows his audience.
ARM-SIDE MISS? WATCH YOUR CHEST. ⚾
Before you change your aim, watch the sequence.
Brent breaks down early chest rotation, an arm-only correction, and a hip-first cue you can compare in your own video.
The cue: during the stride, let your hips lead and let your trunk follow. Watch when the chest turns and where the throwing arm is at that moment.
An arm-side miss alone doesn't tell you the cause. Use this as a checkpoint for your delivery—not a diagnosis from one pitch.
