Come on man, it's not like Grich is some guy on the outskirts, grinding away for an opportunity for a job. If it's some rook or whatever, I'm sure the ump gives him the walk.
But look, I'm sorta just playing devils advocate here. I don't hold it against him for being pissed, I don't think there's a player alive who probably wouldn't at least shake their head to display their disapproval. But I notice a lot of the young Jays (Telez being the most glaring example) who are always protesting called strikes that are clearly obvious strikes, so as one of the more experienced players on the team, he should be cognizant of setting an example... Especially considering that there was no likely chance of a comeback.
