ex-@DrivelineBB; still solving baseball elsewhere.

[Marek Ramilo @marekramilo]

in 2024, we presented the universal theory of pitching— that arsenal mix/match is the antidote to decay, which neutralizes pure stuff over a large sample.

in 2025, we extended it to determine a grand strategy for baseball.

behold the blob of blobs and the grid of grids.

[Jonathan Lucroy @JLucroy20]

This is the most non strategic thing I've ever seen.

@choice_fielder let’s cook on plinko and really ruin baseball as they say

[Marek Ramilo @marekramilo]

a moonshot factory— the inimitable original pitching lab. so proud and grateful to have been a part of the @DrivelineBB mission.

on opening day, 30 teams begin the WS chase. signing off from here to go solve baseball for one of them.

[Lance Brozdowski @LanceBroz]

Fun conversation on pitching development w/ @enosarris, @DerekVanRiper, and @IamTrevorMay today via @ratesandbarrels.

Talked through the best, worst, and risers.

Selfishly think it’s some of the best 40+ minutes out there on the topic. Enjoy!🔥 https://t.co/wfLHWNmV79

Here are the outcome probabilities with resulting win probability. With these calcs:

A take has an expected WP of 19.5%
A swing has an expected WP of 6.5%

There would need to be a 67% chance of called strike for the EV of a swing to meet or exceed the EV of a take.

Two MVPs
Two leadoff home runs

Expect everything #WorldBaseballClassic

[David Adler @_dadler]

Ronald Acuña Jr. and Shohei Ohtani, dueling leadoff home runs in the Japan-Venezuela WBC quarterfinal

Acuña: 106.2 mph / 401 feet
Ohtani: 113.6 mph / 427 feet

[Eno Sarris @enosarris]

oh man, Acuña, Ohtani, leadoff homers, this might be the game of the WBC

[Scott Coleman @scottcoleman55]

Ronald vs. Shohei

[Lance Brozdowski @LanceBroz]

I sent a survey on pitching development and acquisition to 68 #MLB coaches and executives.

Who is the best? Who is the worst? Who will rise?

Results are below. What stands out?

More in thread... 👀

[Jared Diamond @jareddiamond]

A few weeks before Joseph Contreras got Aaron Judge out, he met with his high-school catcher -- the son of former MLB catcher Todd Greene -- to watch film and come up with a scouting report.

It worked to perfection. High-school baseball rules.

[Justin Felder @Justin_FOX5]

**Current** Blessed Trinity pitcher Joseph Contreras gets 3-time MVP Aaron Judge to ground into an inning-ending double play.
He’s 17 years old!

[World Baseball Classic @WBCBaseball]

Expect everything.

17-year-old high school senior Joseph Contreras gets Aaron Judge to hit into a bases-loaded double play to end the ending 😮

[Tim Melville @Timelville]

Out at the Sabermetrics Analytics Conference @sabr, I got to see @hedgertronic, @SamEhrlich, and @connerpelletier present on the Magnus and non-Magnus forces affecting ball flight.

Check out the @DrivelineBB Research & Development Podcast!

[Marek Ramilo @marekramilo]

on strider bump day, consider this dynamics plot, which we covered in the QTd episode: 95 mph is a critical breakeven point for fastballs.

<95: intrinsic stuff value is positive and 1 marginal MPH doesn’t help much

>95: ISV negative and every tick yields large gains in stuff

[Buster Olney @Buster_ESPN]

When the powerhouse schools called, offering NIL money, Jack Ohman nearly changed his phone number.

Two different shapes:

- 47% Split (Less arm side):
90-93, 1371 rpm, 2.2" IVB, 7.8" HB

- 53% Split (Arm side):
91-94, 1471 rpm, 1.8 IVB, 14.3" HB

[Marek Ramilo @marekramilo]

i enjoy these film sessions by ottavino.

here, he spotlights yamamoto’s two splitter variants— a harder SI-like kind for GBs, and a larger-form kind for chases. for all the hype on splitters, their versatility remains an underrated feature.

trajekt as a legit tool for pitching dev

[Nats.Talk @TalkNats]

Paul Toboni say that he has the #Nats pitchers facing "themselves" as a batter on the Trajekt Arc system to see their own repertoires.

[Marek Ramilo @marekramilo]

this is great content but also spotlights trajekt as a legit tool for pitching dev. studying your stuff from the hitter POV can be an unlock.

[KingofJUCO @KingofJUCO]

I was able to face non other than Myself thanks to a $500,000 Trajekt machine at @DrivelineBB

Technology on it is absolutely incredible.
