In our game, a batter walked. On the 4th ball, it got past the catcher. On his way to the plate, our on-deck hitter picked up the passed ball and flipped it to the catcher. The umpire called him out for interference.

How does this get scored? Does the guy who picked up the ball get charged w/an AB? Where may I read about the rule(s) that would cover this play?

Thanks.
