I think we could come up with a good adjective for 90EV. "XXXX exit velocity". I just can't right now.

Also, at this extreme arm angle, is he getting this much iVB from throwing more of a cutter than a classic four-seamer?

Denzel Clarke has an 80% ground ball rate on 12 batted balls this spring. Not this shit again...

Robby Snelling's pitch movement chart from today is *tight*. Not much variation between pitches of the same type.

Otto Lopez, a right-handed hitter, has slashed .219/.258/.293 (51 wRC+) vs lefties in his career, 331 PAs. That can't continue, right? (He has a 109 wRC+ vs righties.)

I'm a noob and haven't thought about this for more than a minute, but what if a Dem introduced legislation to declare war on Iraq. It wouldn't get to a vote, and if it did it wouldn't be passed. Would at least call out the weanie Republicans (and four annoying Democrats)?

I wish arsenal metrics were more readily available. And I wish we had command metrics that actually seem to be predictive.

We pay attention to what we measure.

Doing my first draft and hold. Not NFBC, so not the "experts". This group is avoiding any injury risk but jumping at inexperience risk. Happy to zag, I think.

Curious how Michael King rebounds considering sweepers are not as effective as they once were.

Or maybe good ones are just as effective, but more guys throwing okay sweepers skews the population down in effectiveness?

124 is a Stuff+ number you don't often see.

"Headmistress"?

Can we call Kenin McGonigle "The Professor" or "The Dame" or "Minerva" or something like that?

Random thought on private college pricing: I'd like to see the *actual* amount paid by income tier over time. It's obvious, I think, that listed tuition prices are way higher in order to get more money from those who can pay it, and still charge "lower" incomes a lower amount?

I'm not sure so many things need to be a calculation, yeesh.

I'm also flummoxed by the seeming inability to re-sort columns, either systematically or manually. (I'm two weeks into my PowerBI life)

Not to brag, but I used the term "lognormal" today.

@blandalytics.pitcherlist.com On your SP game charts, I think you should make it more obvious that the overall game score is based on results. And that PLV is, essentially, the game score based on process. Maybe put those two next to each other, and then show stuff and loc as subset of PLV?

I've seen/heard some folks downgrading CAs just because, and the DraftKick app downgrades them via higher replacement level. I don't know why.

No. Patreon subscribers to a baseball nerd thing. Should be better than noobs, worse than pros.

Just grabbed him as my second catcher in a league. No respect.

PowerBI number of decimal places shown as a function of the number of decimal places I tell it to show me:

3: 3
2: 2
1: 1
0: 2

Fun.

You disagree with the rates or the quantity?

In addition to being a war crime, this makes us LESS safe, not MORE safe.
