Stealing Home

[Danny R]

Here is what it says in LL "The Right Call" for Rule 6.06
---
"A batter is out for illegal action when:
(c) interfering with the catcher's fielding or throwing by stepping out of the batter's box or making any other movement that hinders the catcher's play at home base..."
"Comment: Notice in (c) there is no mention of intentional. Again, umpire's judgement is key."

This doesn't answer the question because this speaks of the batter making "any other movement" and it sounds like your batter didn't move at all. But like it says, umpire's judgement is key.
