Ball hits bat on ground

[UmpJM]

blueump,

While you have posed a reasonable "train of logic" regarding the "foreign object", it is not correct.

While contact with a "foreign object" over foul territory does determine a batted ball's foul/fair status, the only "foreign objects" in fair territory where contact determines a batted ball's foul/fair status are the bases/bags (with the exception of home plate).
