I guess I really don't understand the balk rules, due mostly because I rarely ever see them. The third one, as it is explained in the video, is so slight... you'd have to wonder if the umpire is picking on the Sox.

They got less and less egregious, but all three looked legit to me.

I thought the second one was the most slight. That first one was pretty clear. Surprised Bob Davidson wasn't a part of this.
