Nuance is lost here when it comes to pitching. When a Twins pitcher has thrown over 80 pitches by the end of the fourth, they don’t start the fifth. At around 85, they don’t start the sixth. The upper limit on pitches seems to be 100. Paddack seems limited to 80 so far. The bullpen might have a pattern of rest depending on how many pitches thrown over a given period of time for the higher leverage relievers. That would require actual work to follow that usage.
College now has very specific rules on number of pitches and days of rest. It is not unreasonable to think the Twins do not have the same.
