This path of continually asking less and less of pitchers is monumentally stupid. Self-defeating.
What is the point of pitchers who don't pitch?
They're not avoiding injuries. That's indisputable.
I don't think there is such a thing as a "disengagement" with no runners on base.

In this case, the bases were empty.
SWR initially appeared to claim an issue with his pitchcom. But he then stepped back on the rubber and pitched.
I'm not sure how this should have played out. I can't find an MLB rule explaing a pitcher/catcher's rights when claiming pitchcom issues. I don't know if the umpire is required to grant a time out.
I also think SWR effed up by stepping back on the mound. But I don't know if that's a rule violation either.
