For those of you interested in what the answers are for the three rules for the post earlier today here they are. I am writing them exactly how they are written on the card.
Only one run counts. The ball is dead as soon as it lodges in the mask. The batter is awarded first base, and all runners advance one base. If this occurred with first base occupied, and less than two outs. The batter would be automatically out.
This is definitely unsportsmanlike conduct, and the second baseman should be ejected
This is a balk. The pitcher cannot stand on, or astride the rubber without having the ball.
