I used to wrangle big critters. Now I wrangle data. @URAM_Analytics

Your gut says that was a bad pitching change decision.

The data says… it was worse!

Now you can prove it.

Test bullpen decisions in real time!

@MrDelicious13 Me to Will when he loses the DH despite being up 1,000,000 runs.

@soxmachine_josh @JRFegan @SoxMachine Great article! Y'all may appreciate a little thread I put together this morning on what I'm seeing in my pitching change decision making framework data.

Results through 6/21/26 - I would not categorize the Sox / Venable's pitching change decisions as good.

Caveat of this is one way to look at it, but I've got them below the league average in three different components.

The framework really hammers them in high leverage.

@mnl398 the 2026 white sox are 3 games over .500! seems like a good job to me!

For the five of you who get this far: if you want to dig in more, the dashboard is here and there is a link to the methodology there as well.

I also have an app on my site that allows you to test out your own decision making!

Though, it's worth sharing that the framework captures a real chunk of what fuels a team's 1-run record (as you can see in the screenshot).

Point being: decision-making matters on the margins. Right now, the Sox are struggling where it matters most.

@NealMarcus1708 @RyanMcGuffey I’d have to agree with ya!
