Changing a "Foul" call ?

[johnnyg08]

then it wouldn't be a foul-tip once it hits the ground...right? or are you referring to an umpire or "the umpire" who calls a "fout-tip" a foul ball as the OP states?

I interpret it similar to the FED interp of the Infield Fly rule...where the players and coaches are responsible for knowing the rule...the umpire isn't even required to call IFF...while it's probably not a good idea nor look very good...it's not a requirement...unless PU or BU goes out of his way to call it foul and it stops play...well, then we eat it and it's foul. Which would be differnet from IFF.
