I don't have enough autism to go through prior games and see if this is something that's been happening for a while.
Something Kirk is doing is the most likely tell bc if it was Belt or the pitcher or someone else in the field of play the batter could simply look to them directly instead of needing to get the signs from the dugout or 3rd base coach.
Judge's initial explanation was fine with me. He was obviously full of s*** but his explanation was so bad that it was basically a wink and a nod that he was caught. But now today he's acting all high and mighty about it which makes it seem like something fishier is at play.
Either way we need a total and complete shutdown of Aaron Judge playing baseball until we can figure out what the hell is going on. I'd put a provisional asterisk on his 7th place tie last year and then I'd take him off the field, at least for the next 3 days.
