This is a crazy amount of work to get it nailed down like this for easy consumption

Agreed. There should be a cover on that arm rest

I closed it already... just click batter and catcher interference

Make sure to select 2025, not 2026!

I'm not sure why you'd want to WPA this metric

It certainly is valid to do it at the run level, like Framing

Yes, it's fairly straightforward to do so

You can talk to the owners of those sites about including it

And, it would only be baked into WPA if you have (a) a WPA version at the pitch level and (b) you show a change of state following a review

Here you go, the Wilyer Abreu ABS Challenge: the most confident someone will ever be in measuring something moving at 90 mph to under 1 inch:

Blog Post: Tango Prompts Claude AI to replace The Balk Rule

Enjoy...

The third disengagement / no-out is already part of the rule

So, you are saying to remove balks altogether. Which is ok, but we can do a bit better. Think it over...

For those of you pondering coming up with a better rule than the balk rule, Ill get you started

Since MLB implemented disengagement (AND STEOPFF) rule, pitchers are ALREADY highly incentivized to not throw to a base unless they can pickoff the runner

You are half-way there...

It's buried here:

Which leads to here:

And to answer your question: takes-only. Read the above, and let me know if you need anything else

Suppose you have .300 win% baseline: 9-1 player (6 WAR) is worth two 6-4 players (3 WAR each)

But under .250 win% baseline: 9-1 (6.5 WAR) is worth LESS than those VERY SAME two 6-4 players (3.5 WAR each)

Choose .350 win% baseline: 9-1 player (now 5.5 WAR) is worth MORE than 2 x 6-4 (2.5 WAR each)

Depending how you choose your replacement level, your typical great player compared to your typical bench/platoon player can be anywhere from 9X to 22X as valuable

This is why all the talk about "oh, a 6 WAR player has more value than two 3 WAR players" is missing the entire point of the baseline

Right, they might challenge only the easy ones and only when it doesn't matter much (say first pitch challenges with bases empty, 2 outs). That's an easy way to pad your totals, similar to an "empty hit"

What and Why is Umpire's Call #euphoriacricket #cricketplayer YouTube video by Euphoria Cricket

Ah yes, I remember that from a while back. However, watch this. And the ABS-equivalent is the very start of the video.

I see, fair enough, good point

One of the closest line calls you'll EVER see! 👀 #shorts YouTube video by Wimbledon

In terms of broadcast, they *never* talk about the margin of error

Whether they talk about it among folks like you and me, I have no idea

How did you see the Hawkeye tennis line calls?

The preciseness is smaller than the human eye

Which of the two would you give the benefit of the doubt?

... are doing is changing the location of the in/out line where we will still have (other) pitches 0.1 inches from the line

You'd also have to let a team keep a "lost" challenge in the case where the challenge is upheld due to buffer

Suddenly, a simple process becomes complex

For those who want ABS to include a Buffer Zone, in order to give a benefit of doubt to the umpire, it's going to look like this

As you can see, it's going to be somewhat unintuitive, especially if you don't know whether batter or catcher is challenging

In the end, all we...

And then mechanically, how would you represent this? Now you are going to have multiple zones. One if the batter challenges and one if the catcher challenges. And in each of the two, you will have TWO boxes: the strike zone and the buffer zone

All for the sake of giving the ump a benefit of doubt

Run value is 0

Thank you for sharing... so far, Twins batters are 3rd in issuing challenges and 1st in overturns

Challenges, not overturns

As expected, 3-ball and/or 2-strike counts are where the challenges happen, given that it has the chance to impact the final outcome directly

The "other counts" though is still much too high, as batters and catchers are getting only 0.11-0.12 runs per overturn: needs to be 0.20+
