You could see, in the video, that Watkins said something to him and Cave took it as an "oh crap, my bad" moment. He even patted himself on the chest to signal that. I think Watkins told him what had happened, why the Rangers may be pissed, and what may happen to Kepler. Still, stupid. A guy shouldn't have to worry about swinging 3-0 no matter the score. These unwritten rules are so outlandish and stupid. Down with them.
