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."

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

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 🤯

Some personal news: I've joined @fangraphs.com full-time as an Analyst and Junior Developer! Getting paid to do what I love is an absolute treat and I'm so excited to keep working on RosterResource, write the occasional payroll wonk article, and help the dev side with new features!

The Nationals are calling up top hitting prospect Brady House and Daylen Lile, per sources. The Nationals have optioned Robert Hassell III and Jose Tena to Triple-A Rochester.

Final: Nats 2, Rangers 0. Michael Soroka and 3 relievers outdueled Patrick Corbin in the fastest 9-inning game in club history: 1 hour, 49 minutes.

Final: Nats 2, Cubs 0. MacKenzie Gore tossed 7 scoreless to lower his ERA to 2.87. And thanks to just enough late offense from Amed Rosario and Nasim Nuñez, the ace finally earned his 3rd win of the season.

THE FIRST PERFECT SEASON IN COLLEGE BASEBALL HISTORY

new workplace has some nice perks

Just submitted mine as well! Hoping to share some fun stuff about batter decision making. Submit an idea! And come hang out and talk ball with us. docs.google.com/forms/d/e/1F...

Abstract submitted! Deadline is May 15th, if anyone is still interested and has something ready to go. Hope I can see you in Chicago

Fitting models for balls in play is my personal hell

I kind of think this is exactly what happened for better or worse - and with the caveat that this guy is quite well known inside that room but not to the rest of us, who are still figuring him out - I think we may have just gotten the pope that Francis wanted us to get

“Massive numbers of students are going to emerge from university with degrees, and into the workforce, who are essentially illiterate…Both in the literal sense and in the sense of being historically illiterate and having no knowledge of their own culture, much less anyone else’s.”

When I first wrote about spin efficiencies. I cautioned that due to noisy data, it is possible to end up with spin efficiencies greater that 1. Of course, that is physically impossible. The template is best used to average over many pitches. Otherwise use with caution. (1/2)

Ah yes the rite of passage for every Korean male: wasting 18~21 months of your life

I have written a new (unpublished) article on the physics of torpedo bats. Much of what I have to say is more generally about the physics of the ball-bat collision. The intended readership is "baseball people", not physicists. I hope it useful. baseball.physics.illinois.edu/TorpedoArtic...

Okay, I'm going to repeat my Lorde/Weezer theory: 1st album: The big one with all the hits 2nd album: The beloved fan favorite that didn't sell very well 3rd album: The dippy happy one that split the fanbase So if I have this right, the next video should have the Muppets in it

Today was my first day writing full-time for FanGraphs. I tried to make it count.
