With a brief note for TexasGus on how I derive my insights:
If you’re interested in learning how to actually read a Statcast hitter profile—not just glancing at the red and blue bars but understanding what they signal—Juan Soto gives us the clearest possible example. His data is the perfect model for explaining how modern hitting evaluation works.
Before diving into the breakdown, I’m including a short note at the end responding to a great question from TexasGus, who asked how I know this stuff. It’s a fair question, and the answer explains the lens behind this entire series.
Impact Quality — The Biomechanical Power Core
The top of Soto’s profile is a wall of elite red:
- xwOBA (100th percentile)
- xwOBACON (98th)
- xSLG (99th)
- Barrel% (98th)
- Hard-Hit% (97th)
These aren’t traditional “power stats.” These are biomechanical outputs.
They reveal a hitter who:
- generates exceptional lower-body force,
- transfers energy cleanly through hips → torso → barrel,
- repeats his bat path with minimal energy loss,
- and produces flush contact with extraordinary consistency.
This is Soto’s mechanical foundation. It’s why his quality of contact is so stable across seasons, pitchers, and ballparks.
Vision & Discipline — The Cognitive Layer
If the impact-quality cluster shows how Soto moves, this next cluster shows how he sees.
Key numbers:
- Chase Rate (100th percentile)
- Z-Swing% (98th)
- Whiff% (elite)
- Walk Rate (18%)
This is elite pitch recognition. It tells us Soto:
- identifies pitch type extremely early,
- reads spin quickly,
- rarely expands his zone,
- swings only at pitches he can damage,
- and forces pitchers into his preferred parts of the zone.
This cognitive layer is why Soto doesn’t slump the way most hitters do. Discipline travels. Good swing decisions survive bad luck, tough stadiums, and elite pitchers.
Timing & Adjustability — The Hidden Layer Statcast Doesn’t Label
There is no Statcast bar labeled “timing” or “adjustability,” but Soto’s chart reveals those qualities indirectly.
You see it in:
- consistent xwOBA,
- stable barrel rates,
- high-quality contact vs. all pitch types,
- low whiff rates even against elite velocity.
These reflect:
- a late commit window,
- posture stability through rotation,
- excellent swing-plane matching,
- adjustability to velocity and movement.
This is the part of hitting that is nearly impossible to teach, and it’s where the elite hitters truly separate themselves. Soto’s internal timing engine is one of the best in the sport.
The One Blue Bar — Sweet Spot% — Why It Doesn't Matter
Soto’s lone blue bar is Sweet Spot%, which measures how often a hitter produces “ideal” launch angles.
Surprising? Maybe. But here’s the key:
Sweet Spot% reflects precision, not power or discipline.
Soto willingly trades some launch-angle optimization for elite decision quality.
His priorities are:
- See the pitch
- Identify damage
- Control the count
- Hit the ball extremely hard
Launch-angle optimization is secondary. Elite hitters like Soto optimize the right variables. This is an intentional, high-level tradeoff.
What a Complete Hitter Looks Like
When you combine:
- mechanical force (impact quality),
- cognitive recognition (decision-making),
- temporal control (timing and adjustability),
you arrive at the full Juan Soto profile.
This isn’t a hot streak or a lucky season. It’s a fully formed offensive system. Soto’s underlying skills are structurally elite, which is why his performance is so consistent year-to-year.
He represents the destination on the developmental curve—where biomechanics, timing, and approach fully converge.
For TexasGus — How I Derive My Insights (Demystifying RVH)
A quick answer, because the question has come up and it’s a fair one.
I’m not a scout.
I didn’t study biomechanics.
I don’t work inside a baseball front office.
But professionally, I’ve spent decades breaking down:
- systems,
- sequencing,
- performance levers,
- decision architecture,
- signal vs. noise,
- and how complex operations behave under pressure.
Modern baseball analytics—Statcast, biomechanics, pitch design, swing-sequencing—mirror the same patterns. When baseball evolved into force → flow → timing → decisions → outcomes, it started to look exactly like the systems I analyze and build every day.
So the insights aren’t mystical. It’s simply applying that same analytical lens to baseball, the game I’ve loved since childhood.
That’s the whole secret.

I can’t wait! Thank you RVH! And thank you for breaking this down for us. I’m now going to start looking up other players, like Tucker Simien, Tatis… just for fun.
As I was reading your post, it brought back a memory. I recall being in advanced math in the 11th grade and seeing how it was getting harder, I asked myself how I was going to handle Calculus BC next year and wouldn’t Calculus AB just
Be easier? LOL!!
RVH, you get high xwOBA for your analytical mindset.. I’m pretty analytical, but I start to glaze over with this stuff.
The question for a Vientos vs. a Soto: obviously, Mark grades lower, but can he learn to close his gaps with Soto? WYSIWYG, or hope for real improvement.
Ditto for guys like Benge, Reimer, Williams, Clifford, and Morabito - canthey accelerate their needed growth in hitting proficiency?
lol, I hated math until I studied finance. Once I out $$$ to the numbers things started to make sense to me. (Of course, I went to NYC high school so most people on this site know what that means).
I’ve got a ton of partially written work on most of them. Including some of the youngsters. I’ll start packaging that material after my next couple of posts. Short answer: the individual player gaps are measurable & the solutions are becoming more “known”. That’s progress but probably the hardest thing to do in sports is hit a round ball moving in multiple directions at 95+ MPH with a round bat within one second response time. Baseball is a game of failure - they are all trying to reduce their failure rates not increase their success rates. That’s why they make so much damn $$$$
Folks, you're watching and reading a whole new direction on analyzing baseball players
THank God this buy is a CEO of his own company,, or he would quickly be swooped up by another site
Agreed
Shhhhhh
Tom, see below. More to come!
Thanks Mack! I can’t believe I’m having so much fun with all of you. I never imagined I could apply my Mets geek persona with people who find it as interesting as I do. Thank you all for the good vibes!
Now hopefully all this industry knowledge finally creates a winning team so we can start partying next year!
And I might proof read before sending
Excellent work RVH. I too am a proud graduate of NYC public schools. I come from two areas that bear on this sort of analysis: golf playing and coaching on the one hand, and game and decision theory.
One thing I would add to RVH's analysis which I offer as a guide on how not to use this sort of data.. What you don't want to do is to use Soto's actual swing as a model to be emulated by others. The actual swing is simply one that produces his extraordinary results and it is particularly efficient at doing so (i.e. little if any wasted energy) given his distinctive biomechanical drivers. The real skill in teaching, coaching or mentoring is not chasing a model or a picture; it is helping someone use their biomechanical drivers efficiently to produce comparable results. That swing can end up lookiing very different than Soto's. The posture may be different, There maybe different peaks of force, e.g. higher peak for lateral or vertical force than rotational torque, etc.
Moreover, even relative to the level of excellence that all professional BB players exhibit, Soto is an outlier for his incredible consistency across all measurable outcomes.
And this should be a lesson for hitting and pitching coaches as well who are actually pretty new to the technology (which is easy to misunderestand BTW), not to encourage players en masse to change their launch angle or their path or whatever. It can screw up what they do well already and it may not fit at all with what their body does best, let alone what its limitations may be.
From my perspective as a golf coach that the worst use of AI in modern instruction comes from the ever increasing use of it to overlay some great professional golfer's swing on a video of an everyday golfer in order to point out areas of potential and needed improvement if the golfer is to get better. This is crazy stupid for obvious reasons. NEVER chase a picture or a model. And never chase numbers as such.
Take a pitcher for example. Every quality pitcher has some degree of external rotation of the shoulder of their pitching arm. It may well be that pitcher X who has a terrific fastball with a lot of late movement and has won a Cy Young award has Y* of external rotation, and (I have actually seen this happen), a coach encourages his pitchers to do a set of exercises designed to increase the extent of external rotation in isolation without regard to the relationship that the pitcher's current level of external rotation has with other features of his pitching mechanics and his body's capacities. And so on.
There is in fact a very well known golf instructor, who in the early days of trackman asserted with a confidence that bordered on pure chutzpah that he could determine everything he needed to know about a golfer and figure out how to improve the golfer's performance simply by seeing his 'trackman' numbers. Enuff said.
Bravo Gus. Athletes are humans. It will likely take time to learn how to optimize th application of all of this new technology/data. The opportunity is finding & capitalizing the arbitrage moments along that journey… WAIT, that was hedge fund mangers do :)!
Just to use a hitting example: compare in rough terms, Judge's and Vientos' swings. Both have relatively steep paths to the ball. Judge's no doubt at least partially a function of his height and the height of his hands (not at address, but at the end of the loading phase of his swing). Judge had to find a way compatible with his body and its capabilities that would enable him to shallow or flatten to some extent his path. And because he had a relatively efficient swing that created a great deal of potential energy he could put on the ball, he also wanted not just a shallower path but one that could increase his launch angle. So he did two things. He ulner deviated his wrists early in the transition (think of this if you need a picture) as aiming the barrel of the bat down and towards the catcher's head) which shallowed the shaft, and he loaded and pivoted his rotation more around his right or trail leg, which led to his ability to hit up on the ball. Compare that, say, to Ichiro who transferred pressure early to his front leg and rotated around it primarily. That kind of front side dominance is normally associated with 'slap hitters' in the old days, but it can be powerful for some. One of the longest drivers of a golf ball (Cameron Champ) is front leg dominant in this regard, and efforts to change him would probably end up making him a much worse golfer.
So what does this tell us about what Vientos should do, given that he too has a somewhat steep path to the ball. The answer is that it tells us absolutely NOTHING about what changes in his swing he should make. He would benefit if he could seamlessly and with other matchups in his swing shallow his path some. I don't know and neither does anyone else yet whether he can do that successfully and efficiently. People have the swings they do for a reason; it is a matter of cause and effect after all. Can you imagine what damage would have been caused to Ichiro by trying to have him load more into his trail side. This is what coaching is all about !!
Sorry Jules. Bravo to this post.
BTW, my golf swing really sucks - even after trackman. I have zero athletic talent.
