Recently, I have seen assertions that MLB strike out/low average is simply a function of ....trying to swing more "up". I don't think so. Simply put, MLB hitters are there because they conform to the "building code" standard as set forth by Paul Nyman some yrs. back [pcr/pcrw].
Simply put, according to this standard, they know how to create very good posture, connection, rotation, such that they are able to hit high level pitching.
So, what really best explains the high strikeout/low average combination.
A good deal of insight into this question can be found in a recent SI article as regards the "extra-legal" ways that pitchers are engaging in to manipulate the spin rate.
Read the whole article to get the full report.

But a couple of things they site are very important.
The added spin means that the average four-seam fastball drops nearly two inches fewer this year than it did in ’18, according to Statcast, making it appear to hitters as if it’s rising.
So far in ’21, facing fastballs down the middle thrown at 2,499 revolutions per minute or fewer, hitters have batted .330. Facing fastballs down the middle thrown at 2,500 rpms or more, they have batted .285.
From the hitter's perspective why is this "rising" ---basically not DECLINING as much--important?
Here's why: "Hitters spend their entire careers building a library of pitches", explains Garrett Beatty, who teaches physiology and applied kinesiology with a focus on sports at the University of Florida.
"Because they have only 200 to 400 milliseconds—about the blink of an eye—to decide whether and where to swing, they have to extrapolate where the pitch will end up, based on all the pitches they have seen in their lifetimes.
In other words, hitters will tend to "norm" [my term] the environment. Meaning, for ex. that if they are TYPICALLY facing 80 mph. fast balls, they will [tacitly] program their timing for that speed.
Speeds at 90--or 70 will thus be much more problematic.
The same is true for the TYPICAL degree of incline of a fast ball. Meaning that if the typical degree of incline is 9 degrees, 10-12 degree of incline will be highly problematic.
Creating greater frictional force can certainly enhance the spin rate such that the incline decreases ,ie., the ball, relative to the "norm" ..."stays up" slightly longer.
Some yrs back a minor league pitching instructor from the Cardinals who worked under Brent Strom showed me some data regarding the top strike out MLB pitchers. They showed LESS of an incline [let's say 11 degrees vs. 9].
He ask me: "Does this differential make sense as regards their strike out ability?" And I said "absolutely."

Based on the "norming" I explained above!!
Correction: I should have written "cite" as opposed to "site."
Correction: In this and the above tweet I should have [I thought I did actually] included quotation marks. These comments are excerpts from this very thoughtful article.
Someone mentioned [asserted] that thrown fastballs were down this yr. This is completely irrelevant to my argument [and the data I cited] as regards the differential spin rates of fastballs as they effect batting average.
My argument had nothing to do with the notion that greater frictional forces at the fingers could enhance the movement potential of non-fastballs.

I recently received a msg asking about a recent tweet as regards the back leg flexion action. An action, I argued CAN help facilitate ["free up" as I sometimes say] the hip rotation.

To the clips I showed already let me add 2 more:
A Bonds clip:…

and a Hamilton clip [2008 HR Derby]
As regards the action of the back leg ,both are similar in that both show a good deal of knee flexion AS the lead heel starts to go into foot plant.

As I have argued for yrs. good hitters know how to create movement that facilitates good hip rotation.
As I have argued, the legs do not CAUSE good hip rotation. But they can help or hinder hip rotation.

Here's 2 clips of Bonds /Kent:
Note how quickly the back knee flexes --as they go into foot plant. This can help to "free up" [my term] the back hip rotation. Why?

Imagine if you as a parent brought your daughter to me to help her learn how to swing the bat better.
Then later you learn that as a predicate to this expectation, I spent several hours with her mandating that she watch a Netflix "documentary"[sic] on America's historic racism.
And further I then demanded that in order for me to allow her to hit with me I insisted that, in no manner, could she question the quality/accuracy/fairness etc., of the documentary. What would you think of me as a teacher of hitting?
Would you deem this as an acceptable part of the exchange of your money for my expertise----in the context of a teacher of hitting?

For over 30 yrs. Trump has variously been talking about the hollowing out of America's industrial base.

Here's a pretty dramatic visual of this [click on the icon in the lower left hand corner to see this]:…
Regardless as to whether one loathes or idolizes Trump, I am hard pressed to see how this chart displays a positive trend for citizens of the U.S.
As one NYT writer/author wrote about some yrs. back, those countries who do not make things cannot then innovate to any real degree ,i.e., you have to make things in order to then improve [innovate] upon those things. Bottom line:

A phrase that I have seen about hitting over the yrs. is along the lines of things like: The hitter needs to be more athletic, or, you are taking the athleticism out of the hitter.
One operative principle I have utilized over the yrs. for many such assertions is that of ......
...questioning the premise. In the case of the phrase "you're taking away the hitter's athleticism" it amounts to asking: "Define athleticism."
Here's one dictionary version: "the physical qualities that are characteristic of athletes, such as strength, fitness, and agility."
But this definition, similar to the above "taking away athleticism" is equally vague in that ALL athletes have SOME degree of, "strength, fitness, agility."

And one more thing for tonight [before I return to my bunker to read a bunch of shit!]; Not too long ago, someone blocked me ---apparently as a result of me simply pointing out that I thought their description/analysis of a hitter was flawed.
In no manner [I don't think] could my argument be construed as any kind of personal attack. Simply put, I disagreed with their interpretation and tried explain this based on my understanding of movement [based on 20 yrs. of practical and technical info].
Rather than trying to engage me he simply blocked me. Those who know me know that I am someone who is well practiced in the art of engaging all kinds of views on things. MY operative view is:
