From a Sports Illustrated Story: Though PitchCom comes with a standard collection of pre-set tracks (“four-seam fastball,” “curveball,” and so on, available in English, Spanish, Japanese and Korean), a number of clubs decided to record their own. Some are just basic calls done in a different voice. A few are highly specific to a given pitcher or scenario. Others are simply motivational. One reliever had his team program in the voice from the video game Mortal Kombat saying “Finish him.” (Who wants to hear “heater” when you can hear that?) One club has a far more profane version of “Throw it over the plate, you wimp.” And Guardians catcher Austin Hedges has become known for his “f— yeah” button."
