A visor has no bottom. It is simply a piece of fabric connected at both ends to form a circle. It cannot hold anything, especially not baseballs. And definitely not baseballs that are approaching at a high rate of speed. Don’t tell that to this Arkansas fan who attempted to catch a home run ball with his visor.
Seriously, you cannot make this stuff up. We can only hope he was under the influence of a few adult beverages and did not consider that a bottomless visor cannot hold a baseball.
