Hoffman 260 Batters Faced in 2025
Santander 209 PA
HR rate for pitchers takes like 1320 BF to be 50% stable
Just funny to compare stat reliability between a full season RP getting slammed (and now everyone thinks he sucks) and a position player who got hurt after 200 PA.
The only pitching stats stable in 260 BF or less would be things like K rate, BB rate, GB and FB rates. And of course more granular stuff like velo and stuff metrics which stabilize quickly. You (we) should be regressing Hoffman's HR/FB rate like 80% to the mean (whatever that is). All slash line stats are not nearly stable. LD rate and HR/FB not close to stable.
However, for hitters 209 PA is enough for 50%+ stability on all of: K rate, BB rate, HR rate, ISO, GB and FB
This means nothing because Santander was hurt so you can just throw out most of his 2025 sample, but if that caveat didn't exist you could say that Santander's 2025 numbers actually mean more than Hoffman's. As far as determining how good the player is.
That is to say, if you think Jeff Hoffman sucks than to be consistent you should not even want Santander to come back.
