wRC+ and other "Park Adjusted" stats

[Donn Beach]

True, they probably have there own formulas to begin with, teams have their own analytical systems, Scott Boras has his own proprietary analytical system. Fangraphs and whatever is more fan oriented, fantasy oriented

JRod and Rutschman were #1 and #2 in ROY voting with both having 5.4 Fangraphs WAR. But in 2022, T-Mobile favored right handed batters. Should JRod's WAR have been lower?

I don't know about how this affects WAR, if it does at all. Simply a gripe about wRC+.

But yeah, if you're going to use wRC+, it should probably have been calculated using the RH numbers, not the blended RH/LH number.

Last season T-Mobile had an overall park factor of 93.

LH was 86.
RH was 98.

If anything it seems like another good reason that "park adjusted " stats that use a single park factor in their calculation are nonsense.

It's going to vary every year depending on things like how good our pitching staff is that particular year, which in itself is stupid.

Any reason to believe that MLB front offices don’t adjust wRC+ for handedness?

The general public apparently is entitled to only the generic wRC+. We’re Little Leaguers trying to hit big league pitching.

Kudos, though, for raising a good issue regarding wRC+.

No, of course front offices likely have a better stat. Maybe not the Mariners. But most teams.

Or, they at least probably understand that you shouldn't judge JP Crawford and Julio based on the same T-Mobile number, so they probably ignore the "park adjusted" stats altogether.

As a thought experiment, if:


Overall League OPS in T-Mobile was .750

Right handed batters in T-Mobile have a .700 OPS

Left handed batters have a .800 OPS

________________________________________________________

Now imagine if we took JP and Julio's numbers and we "park adjust" each using the .750 number......

It would make zero sense, and would just skew the reality of the numbers for every player.

It would make JP look like a better player, and it would make Julio look worse.

But that's exactly how they're calculating wRC+ now.

All of the key metrics that Jerry is required to focus on have $ signs in from of them...

Wish it wasn't so true!

My issue with it isn't how teams are using them. I have no idea if/how teams utilize these stats. The complaint is with how fans are leaning on them like park adjusted is more accurate than legacy statistics.

For example, somebody mentioned the other day how some nerd vlogger thinks OPS is an antiquated statistic because they have things like wRC+ now.

Well. since wRC (weighted Runs Created) and we expect one WAR for 10 runs created, it would be silly to think it doesn't affect WAR.

It doesn't matter though, that those who wanted Trea Turner who has a lower OPS than JP, those people were wrong about Trea Turner, or CC improving the offense.

I would say anything relying on "park adjusted" numbers has an obvious problem currently.

And, absolutely, the way to improve the offense the last couple years was definitely in the 1B/DH market, not the highest paid position on the field.

I try to use multiyear stats when comparing players for acquisitions. Front offices probably use more advanced stats. I can imagine something similar to xwOBA with adjustments.
