Ball rotation

[okla21fan]

I follow standard ball rotation procedures in NFHS and ASA Championship play but rarely follow it in league play and 'local' ASA tournaments (mainly because the UIC tells us not to)

My question is, what are the pros and con of ball rotation and why do we still use it? (I remember back in the 80s in some men's fastpitch where each team supplied their own balls, there was a need for ball rotation, but today with most tournaments and high school home team supplying balls usually the same brand and such, I am not understanding the reasoning behind it)

When I do enforce ball rotation even at the HS level, I receive much push back from teams and even some partners saying 'that the pitchers should be able to throw what ever ball they want to'.

discuss?
