When he’s on the mound, Clemson left-hander Ryan Ammons will feel a little tingle on his right arm.
No, nothing’s wrong. It’s not a tweak or twinge.

It’s being replaced by a coach in the dugout pressing numbers into a keypad corresponding to different pitch types and transmitting the information to the mound.
