When S played there were very strict rules about pitchers and use (2011). (E.g., 35 pitch inning and pitcher is done; over a certain number of pitches and he's done for multiple days, etc.) Current rules look the same. https://northwoodsleague.com/a...pitching-guidelines/
It is his college coach's job to coordinate with his Northwood's manager so that both are on the same pitching page.
Even a full season contract can be shortened once max innings are reached.
Umpires were inconsistent - especially if your magic pitch was a breaking ball (both the zone and checked swings were challenges).
Yes, it is a grind. It's the closest pro-ball experience a kid can have while playing in college; long bus rides, and motels, no days off. I've known guys to alter their baseball dreams because of that grind.
