 So basically, for those that don't know, players can go in between their at-bats, and they can go down in the tunnel and basically pull up any pitcher and virtually face them and get a look at their pitches, their delivery, and the whole thing. I can't imagine pitchers love the idea of this being a legal technique. They don't, but who cares? I mean, it exists. And by the way, they're all trying to do everything they can to get hitters out, and this is just a new tool.
