not only are the shapes excellent, the delivery is so smooth and controlled, the 4.5% walk rate last year doesn't look like a fluke

cutter shape today is back to what it looked in 2024. there may have been some calibration issues in the first start

it's just a pretty rare (maybe unprecedented) combo of K% and GB%

i think it's probably grading out a bit better than it should bc of the arm angle estimate, but yea if he can add a tick of velo and an inch of carry it's going to be a plus pitch

Leonardo DiCaprio quietly funds a tiny library in the middle of LA A branch of the city library was built on the grounds of the actor's childhood home.

as this is my neighborhood library, i'd like to take issue with the assertion that it is "tiny." it is decidedly medium-sized

ya that's fair, probably it wouldn't be worth the confusion of the different zones, but the pro case (as i see it) is less about giving the ump the benefit of the doubt and more to ward off concerns that the system is being precise to an unreasonable degree

i'm thinking sky's fuzzy zone idea would actually be good PR vs pretending ABS is operating with unbelievable levels of precision

it's been reported around 4mm for tennis calls, don't think i've ever seen a publicly reported value for pitches

i'd be fine with deferring to the original call if it's within hawkeye's margin of error
