LBR - What's a Play?

[Texasbock]

My understanding of "making a play" within the context of LBR is anything that the pitcher does to cause the runner to react. To me, that leaves a lot of room to the umpire to decide whether or not the pitcher is indeed doing anything to cause the runner to react.

Simply eyeballing a runner does not seem to fit that definition. But if she were making any kind of head or shoulder movement simultaneously while eyeballing would be a different story.......
