Penalty - Balk or Ball if no runners.
There you go - update an existing rule in less than 50 words and you don't need a line on the field. The home Plate and 2B umpire's are in easy position to call it. Hope it never happens.
I'm picturing the baseball version of a hockey face-off where the ump is yelling to the CF to take a step right, and he moves an inch... then moves back left as the pitcher winds up.
