Comparing Yoshinobu Yamamoto's four-seam fastball to his splitter

up and is a on top of the bat. And then

we've got the split finger here where

he's got the railroad of the laces

that's straight away where the logo is,

and his fingers are on the outside of

it. So, it's a splitter grip, and that's

going to fall off

to the right. His right finger there is

going to be the last to touch it right

there. So, it's going to be spinning

uh off of that finger, and that makes it

go towards his right side. That's why

they call it arm side run. That's his

arm. It's going to run that way and come

into the batter and drop off a lot. So,

those are three different pitch grips

there, very fun to look at. Here are two

of them freezed up. There's the splitter

and the four-seam side by side and the

spin that comes off of them. You can see

one is tight and spinning a lot, and one

does not have a lot of

uh spin, not a lot of revolutions.

Revolutions per minute? Revolutions.

Why'd I Why'd I doubt myself? That's

just sounded weird when I said it. And

here is an overlay where I tried my best

to sync them up even though their

cameras are moving so you can see

how they look side by side and the

difference. One just shoots out and the

other falls down.

But for a little bit from the batter's

point of view, he can't tell which one

is which. So, that is some fun editing

to showcase how the pitches are doing

what they're doing.
