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.

How our models viewed this pitch: 60% chance of swing, 40% chance of take If no swing: 0.5% chance of CS If swing: 63% chance of whiff Model trained on MLB data so not accounting for WBC umpiring, but not surprised our swing decision model had this as an ELITE decision

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... 👀

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. wsj.com/sports/basebal…

**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!

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 😮

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

in which we untangle model dynamics to price marginal velo/bat speed gains in terms of expected stats/wins/dollars gains using tools like the moneybarrel script: what's the value of 1 MPH? a riff on a classic problem in high-frequency trading: what's the value of a picosecond?

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. youtu.be/fKDtEV1CnhI?si…

Keep an eye out for my next presentation with @hedgertronic and @SamEhrlich as we take our stab at solving pitch physics👀. We'll be presenting at the @sabr analytics conference on 2/27 here in AZ and should be around the conference all weekend. Come say hi!

Last year I set out to see what biomechanics patterns are present in pitchers with good command and presented my findings @sabr. This project fundamentally changed the way I view command and repeatability. The long overdue blog is out! Check it out here: drivelinebaseball.com/2026/02/the-in…
