I honestly can't believe I even have to explain this but there are so many reasons that this is as stupid a 'controversy' as I've ever seen.
1) You can't steal signs illegally anymore, it's fucking Pitchcom. If the catcher or first baseman or whatever are moving early, that's on them (I don't think this really happened).
2) The terrible reliever threw five sliders in a row, the one Judge homered on was dead center of the zone. It was as bad a pitch as you will ever see.
3) Boone got tossed a pitch or two earlier after a horrendous strike call, nowhere near the zone.
4) Judge was named captain this past winter, and since then, he has really taken the job seriously. His story that guys were still yelling at the ump in the middle of his AB and he wanted to see who so he could yell at them later makes complete sense to me, especially since he was asked right after the game.
5) If NY was cheating somehow (in an away game, mind you), why was it only in an AB in a 6-0 game against a scrub reliever? Why was it just Judge, no one else, no other ABs, none of Judge's earlier ABs?
I'm sure there's more but that is enough, damn.
