Seems like a whole lot of whining. Were they REALLY out of the box, or did they just cause problems and frustration for you team, trying to get them out, so in your mind they must have been "constantly" out of the box? Slappers are the most exciting part of the game, they can be very difficult to stop, but try and stop them yourselves by pitching better and playing tighter defense instead of hoping the umpires stop them.
