Baseball game rules.

The batsman and the glove-wearing team are not on the same team. The batter is the attacking team and the glove-wearing team is the defending team.

The batter must run four bases counterclockwise at a time (called a run) from the time the batter hits the ball to the time he picks up the ball, then returns to home plate for 1 run.

If it's in the middle of the run and not on base and the ball is returned, you're out. The batter conceded 3 outs and threw 4 bad pitches, sending the batter straight to first base.

Prohibited conduct:

1. Attacking opposing players, referees or spectators with inappropriate language.

2. Calling "time out" or interfering with the pitcher with other language or certain actions during defensive activities in an attempt to cause the pitcher to commit a foul.

3. The fielder shall not stand in a position that obstructs the batsman's sight, and shall not intentionally interfere with the batsman in an unsportsmanlike manner.

4. Touching the referee's body, talking to the referee or showing intimacy.

5. Acts that incite the audience.
