Every Called Strike + Swinging Strike in the Playoffs that had a 130 or more TimStuff+ Value.

So what I gather from this video is Kopech’s heater is godlike

[@markowojtkowiak7685]

Is that a sinker? Or is it a 4 seam, its got crazy arm side movement

[@_michael_g]

@@markowojtkowiak7685its a 4 seam

[@Strattbatt]

@@markowojtkowiak7685it’s a four seam

[@sir_Yosemite]

4 seam with great vertical movement vaa and velo

[@Autistic_Tarkov_Guy]

@@markowojtkowiak7685 so it's a 4 seam. but he holds it a little odd on the release so it moves arm side almost entirely horizontal. it's gnarly to see

Alternative title: Michael Kopech gas and a couple other dudes

[@WillTheTrainFan]

Watching Kopech pitch just satisfies my brain so much, his mechanics are so pretty and his fastball looks like it doesn’t drop at all

[@aljon5947]

whats TimStuff+? /what difference compared to stuff+

[@TimStats]

TimStuff+ is my own personal Stuff model. It has slightly different inputs than Stuff+.

[@michaelmagdziarz7333]

How did you develop it?

[@TimStats]

@@michaelmagdziarz7333 I used an modeling package called XGBoost and modeled for expected Run Value using inputs like Velo, Movement, etc.
