Worthy of the thumb?

I don't know what Greinke said, but it's pretty clear Holbrook judged Greinke was showing him up. Pro umpires don't generally toss people out of the blue, and IMO Holbrook is entitled to the benefit of the doubt.

If the EJ makes players think twice about throwing their little tantrums when something doesn't go their way instead of just sucking it up and getting back to work, IMO that's all to the good.
