After giving this careful thought, there are three likely scenarios/explanations for what is going on here.1. This old man is confused and doesn't even know where he is, let alone at some kind of Colorado Rockies fantasy camp and reacting poorly to a pitch at his face.2. This is a gag.3. This old man is charging the mound* to rearrange the face of the man who just came up and in, and had to be restrained by the umpire.Obviously, we all know it's option No. 3, we're just lucky the umpire was there to step in when he did. Old man did not look like he was going to drop that bat anytime soon.h/t Telly2Putts*We are using the term "charging the mound" as a term of art widely recognized in baseball. This gentleman is clearly not moving swiftly, but he is making his way toward the pitcher's mound, and thus charging it.
