Not sure I have ever seen a 77 Stuff+
I think there must be a measurement mistake?
His velo is down 1.1 and 1.4 and 1.9 mph on his fastballs and cutter
Down 0.7 in his slurve and up 0.4 on his changeup.
This is all bad news but 94 stuff+ to 77 stuff+ kind of bad news???
He has a 70 Stuff+ since July 1st (11 games)
Interestingly, SEVEN of the worst EIGHT qualified Stuff+ seasons in recorded history (since 2020) are in 2025. So something has changed with the model this year.
Berrios' 2025 would be the second worst ever, behind 2025 Zack Littell. Here are the worst 30 qualified SP seasons ever:
