Don't know much about him but here is a blurb I found from Baseball America
"Stanley is just 6 feet, 190 pounds, but he's run his fastball up to 97 mph this spring—which was eye-opening for someone with his command—and sits in the 90-93 mph range."
In a Great Lakes game in April, he was sitting 91 with some 92,93 per the stadium speed gun (which maybe low - Bimbo says don't trust those guns). At the end of the game, he was throwing a few 94s but mixed in a lot of offspeed stuff.
And, if you look at his splits in our 4 games in Lake County (for a college pitcher to get placed there in spring is a good compliment from FO), in 38 PA he had .114/.299 BA/OPS (lefties stats weren't as good). Yet, 19 Ks in 13-2/3 inn with 5 walks and 9 hits ain't too bad for a guy who hasn't pitched since April.
So with limited 2022 data, who know what he can be next year but with a lot of 21 draftees ... it is interesting what the Guardians can pull out of him.
