Fastball spin rate around 2200-2300 is not considered good. Both higher and lower is what they are looking for.
The farther away from 2200-2300 the better, either lower or higher.
This year there is a HS pitcher that has a higher spin rate on his curveball than any recorded in the Big Leagues. He has done this several times in different places. Of course, in his case you don't need anything but eyesight to know his curveball is a doozy. Not often that you see a highest level prospect that has a curveball grade out 2 grades higher than his fastball.
