With the recent "dirty hand" episode we need to take a pulse from the HSBBW experts. I'm sure that the feeling here will weigh heavily with the MLB rules comittee.
Personally, I look at it as an appeal play and it is up to the coach to raise the issue. To many times we see that certain pitchers have been given a "grey area" in regard to the strike zone, balks, and many pitchers in the league have varying levels of relationships with umpire crews from "favorite son" to "hate that guy". I can see where this mentality could be carried over to this issue also. Leave it up to the teams to choose their battles.
