so far tonight bad bunny has sung more reggaeton songs than the patriots and seahawks combined

I rarely watch football, how common are penalties for unsportsmanlike conduct??

The 0.5.0 version of my {brms} + {tidyverse} translation of McElreath's "Statistical Rethinking" (2nd ed) is up! solomon.quarto.pub/sr2/ 1/3 #rstats

I wasn't able to contribute this year, but I'm definitely putting in an order – and I highly recommend that you do the same!

"The result isn’t optimization, it’s about survival" Really enjoyed working on this piece with @jrodrigues39.bsky.social on how swings age, building off work from @justinochoi.bsky.social. Link to the code behind it below! www.baseballprospectus.com/news/article...

Hi, BlueSky converts. Probably deserves some updating, but here's a list of baseball analytics nerds if that's up your alley. go.bsky.app/GZjLuxK

Really enjoyed this article from @benclemens.bsky.social!

Hey, SABR hasn't put both its feet into bluesky yet (I know, a lot of its people have) but this is a good time to remind you that the SABR Analytics Conference Research Awards are open for nominations. When you have a few minutes, please nominate some of your favorite baseball research from 2025.

The code is all here! The raw data is masked, as that is proprietary @baseballprospectus.com data. But BP subscribers should be able to access the same data via the leaderboards to recreate a Fully Operational simulation: github.com/bwoodrum3/ws...

Bat speed aging curve, but this time I account for the fact that we are less likely to observe very young/old players. The corrected curve declines less rapidly early and more rapidly later compared to the regular curve, which seems like the correct inference:

Game 6 ends on a game-winning double play. The Dodgers managed to escape the ninth inning and force a Game 7. Incredible stuff.

Is AWS being down an omen about the fate of the Mariners

Alright third of the way there, keep it up boys

Gotta give props to last year’s #SMTDataChallenge winners, who created the Snell Tool (snelltool.com), which tells when to pull the starting pitcher. Tried it with Snell just now, and it said to pull him after the 8th. Looks like Dave Roberts agrees!

Yeah just gonna need Yamamoto, Ohtani, and Glasnow to throw CGSOs. Thanks

60 home runs for Cal Raleigh. Incredible.

Why did Luis García Jr. get fooled so badly on this pitch? In my article representation of my SaberSeminar presentation, I answer just that and explain how visual uncertainty influences pitch tracking and helps to explain swings. Link below. www.mlb.com/video/luis-g...

Working on a "generalized" version of dynamic dead zone (DDZ) that doesn't require any assumptions about the variables' distributions. You only need to specify the covariance structure, which is Gaussian for the sake of convenience:

Every so often we check in on the models

Induced vertical break, spin efficiency, seam-shifted wake—what do these buzzwords mean for a pitch trajectory? Explore using my Statcast-based pitch visualizer (physics modeling based on work of @pobguy.bsky.social). Updated daily with new pitching data! gabes135.github.io/pitch-graphic/

Cal Ripken Jr has missed 3,765 consecutive games

Alright, I've tidied up the repo and added my presentation. Thank you to everyone who was at @saberseminar.bsky.social yesterday! Was a pleasure to meet so many bright and interesting people. github.com/justinochoi/...

You don't truly appreciate how fast Korea's wifi is until you're standing in an endless line for border control at O'Hare

I really enjoyed chatting with Hannah about the ups and downs of working in baseball -- and my decision to not do that anymore.

Welp, here’s the dumbest #BoothViews I’ve ever done. Here’s how it played out as my voice gave out ending today’s broadcast 🫠😂 glad Bulldog got a kick out of it!

America needs one of those language authorities like the French have so every person who spells it “woah” is immediately arrested.

During grad school, I sent actual letters through the actual mail to five GMs, asking how a 25-year-old with an MFA in poetry and no other credentials could get involved in baseball. Only one responded, and the answer was some (polite) version of, "I regret to inform you that your dream is doomed."

Sleeping Man Flanked By Laptop, Phone, Earbuds Like Egyptian Pharaoh Buried With All His Treasures

Cade Cavalli's 1st inning back in the majors: 1-2-3 with 2 strikeouts on 13 pitches. Fastball was 97-100 and sharp. Curveball was 88. Changeup was 91. Couldn't have drawn that up any better.

"prompt engineering" is still one of dumbest phrases i've heard in my life

Welcome to baseball immortality, Ichiro Suzuki.

We have our first NPB team sponsoring Saberseminar this year--the Chiba Lotte Marines. They'll also be giving a talk about NPB and how the league is different from MLB. Really excited for this one! Reminder that ticket sales and sponsorships are still available here: www.saberseminar.com

This is a cringey thing to do but I am looking for a publication that would like a nice big piece on Oasis from someone who has a deep knowledge of the band, their subculture, and is attending two of their hometown shows (me). I also have a lot of thoughts about commercialism in music. Thanks!

JACOB YOUNG ARE YOU KIDDING WHAT A CATCH 🤯
