Detached equipment (OBR)

[David Emerling]

I need an OBR ruling on this:

Nobody on, nobody out. The batter swings at a pitch in the dirt for strike three. The ball squirts away from the catcher by only a couple feet and he is having a difficult time finding it. The batter begins to sprint to 1st. The catcher removes his mask and eventually finds the ball at his feet. Using his mask, he scoops the ball into his glove and then throws the runner out at 1st.

Again, using OBR - would the batter-runner get a 1 or 2 base award?

Thanks!
