I didn't ask if most did it, I said how many? 1 in 20? 1 in 30? What I will say is that if they called it every time on somebody as high profile as Bahl then that would certainly send a message. Doubt they have the gonads to do it though..
Like I said, I don't know if it gives a competitive advantage or not. Some say yes, some say no. If it doesn't then get of the rule so we can argue about something else on here...lol.
Yeah, no doubt there's trepidation amongst umpires over calling out one of the sports rising stars.
Check out Barnhill's career stats, which I just posted. She was still very effective, but batters got many more hits off her, once she was flagged for illegal pitching, i.e. enforcing the rules evened things out more between the defense and the offense.
