Spent the last week "replicating" several sabersem presentations from the last sabersem. Was pretty fun! Going to highlight each one I did here. Shoutout to @srbrown70.bsky.social for the list of slides, very helpful.

@enosarris.bsky.social and I discussed Zack Wheeler's outlook following a TOS diagnosis, Samuel Basallo's extension, Shane Bieber's new kick-change, and takeaways from Eno's trip to Saberseminar.....

Over the weekend I gave a presentation @Saberseminar about my research on torpedo bats, based on computational modeling. Experimental results are expected soon. Non-trivial result: Width of sweet spot is potentially greater for torpedo.

It was a good one. Our best yet by fundraising--we'll hit, or at least get close to, $75k total--and a ton of great talks. Happy to see everyone, happy to see a lot of students get interviews, and excited to continue growing next year.

Well. @saberseminar.bsky.social 2025 officially in the books. Thank you all. ❤️

Dan Eck presenting his work on the Full House model that was recently featured in the New York Times!

Today I heard Jack Olszewski at @saberseminar.bsky.social describe his pantomime of Trunk Lean as "looking like a teapot" and I'm not sure I'll ever think of it any other way.

Zack Borowiak with a great visual of "indirect" framing runs--showing how batters tend to swing more outside the zone against good framers. This value isn't captured by traditional framing models.

Enormous thank you to @saberseminar.bsky.social for having @enosarris.bsky.social and myself to talk about imputing arm angles.

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.

Quin Yuter from Northwestern is talking about Predictability Score: a new way to measure pitch sequencing.

Round 2 for Driveline, this time Jack Lambert and Marek Ramillo, now on pitch mixes and recommending changes to them.

Another student talk, now from Zachary Levitan--on Computer Vision and measuring pitch control. Neat topic already

This was from Gabriel Applebaum's excellent talk about batters eyes at different MLB parks. Great research and follow-up in speaking with opthalmologists and experts in visual perception.

MLB parks are easier to hit in during the night, AAA parks are easier to hit in during the day. Hypothesis is that this stems from lighting quality.

Winding up, the presenters come up with a way to recommend changes to hitters' swings and determine how valuable those changes will be. Really neat quantitative approach to player development.

Interesting (and intuitive) inverse relationship between power and contact with swings. You can have one or the other, but notably, power is overall much more valuable than contact.

Two guys from @drivelinebaseball.com, Connor Pelletier and Sam Ehrlich, are up now to talk about bat paths and an analysis of some of the new data from Statcast.

Genta Ikawa speaking on a stage at the sabermetrics event Saberseminar

Genta Ikawa from the Chiba Lotte Marines discussing the use of sabermetrics in Japanese (NPB) baseball. Trades are very rare, so the teams rely heavily on drafting and developing talent.

A man stands at a podium in front of a large white projector screen. The title of the slide reads: “How sabermetrics is applied holistically in NPB,” by Genta Ikawa (Chiba Lotte Marines; Team Strategy & Research and Development chief Analyst)

I’m down at IIT hanging out at @saberseminar.bsky.social. So many great baseball talks today, but this one on the use of sabermetrics in Japan might be my favorite. (cc: @danevans108.bsky.social)

(wind AND other weather conditions, of course)

Abhi Kesbat from @weatherapplied.com schooling us on how the wind impacts home run and fielding probability. Highlights how wind can be very different depending on trajectory and precise timing of a hit.

Next up: @srbrown70.bsky.social with an innovative way to study where batters *expect* to see pitches based on their actual swing angles and how they miss

Jessica Fackler with an interesting talk using Support Vector Regression to examine hitting as a function of pulling the ball

Justin Choi up next with Bayesian hierarchical models to determine where pitchers ought to throw the ball.
