Have you read anything about the RPM on fastballs and how important it is.
Where I've seen it:
- The tweet comparing Wade Davis and Hatcher
- Jeff Sullivan's (think it was his chat) chat yesterday when he was explaining why Nathan Eovaldi has the velo but isn't elite.
- just now in this post.
Is there something to the spin or revolutions on the fastball?
I'll go find the chat and copy and paste what he said about Eovaldi.
