Detached Equip - Ball foul

[Whowefoolin]

Rita,

Most catchers, when not using their masks on their face, often fling it off out of the way. Very seldom do you see one carrying it around with them as they chase down base runners, pop-ups, wild pitches, etc...

So it is not just like a hat. And when is a ball a foul ball? When it is properly touched (or comes to rest) over foul territory. So if ball is still rolling, and over foul territory, it is theoretically still a fair ball. So if the catcher, touches it with his hat...err...mask, then he is touching it in a manner that is illegal.
