Every minor league game I go to, I always see one or two people (young guys and presumably not scouts) in the stands behind home plate charting the pitches.
Is this usually the next day pitcher, yesterday’s pitcher, or someone else?
How detailed are they in charting pitches? Are they simply recording pitching data, or making notes on their opinion on how to approach hitters, or observations about the pitcher?
Is this data the “official” data for the team, or simply a task to get them thinking and learning about pitching?
Any info on why the club has them do this would be appreciated.
