I think [MENTION=7875]Rocketech[/MENTION] point is at this level you don't HAPPEN to be illegal...you are illegal and you KNOW you are illegal you just don't care because as Barnhill told you "I never get called for it".
More to the point if it was called they would correct it granted the leapers could make easier corrections than the replanters and the hard part is I don't think Barnhill could make any correction at this point if she got called for several IPs in a row she would have to get pulled, I think someone like Katlin Lee probably could make the change just think hard about dragging her foot or push out not up some kind of cue that would probably work short term.
Based on my experience [MENTION=7876]Rocketech1[/MENTION] is way off. I have a bit of experience with pitchers and even in the SEC they are not fully aware of every body movement. They may be unaware or even sloppy with their mechanics, but only a handful like Barnhill are doing it by design to gain a competitive advantage. To your point for all but a few the issue can be resolved with the application of a minimal amount of focus with zero adverse effect. If the rule was properly enforced those pitchers would make the adjustment in short order leaving only those who seek to deliberately work outside the rules.
