I felt like coming unglued but figured the obnoxious route would not go well and heckling a teenager trying to pitch isn’t a good idea. It is the blatant cheating part that is frustrating; at least hide it better!!
Relax and enjoy the game. I was told many years ago, when I cared about IP's, that I should only worry how our pitchers pitched, and stop worrying about how the opposing pitchers pitched.
