Hitting and Baserunning
It is strongly encouraged with 2 outs that a pinch runner is allowed for catchers.
All Players while in route to home plate must slide or avoid contact if there is any reasonable chance that a play will be attempted at the plate. Failure to do so in the umpire’s judgment will be an out.
If in the umpire’s judgment, the batter throws the bat, the batter will be given a warning for the first offense and will be called out for any subsequent offenses, and the ball is dead. All runners will return to their previous bases.
Runners may lead off and steal bases, with the following exceptions: -During the 1st half of the season: 1. no stealing home -During the 2nd half of the season:
no stealing home on a pitch (unless on a wild pitch or passed ball); and
no stealing home on a throw from the catcher back to the pitcher (unless a wild or missed ball back to the pitcher). -----During the entire season: 1. if the catcher or pitcher otherwise throws the ball to 1st, 2nd or 3rd base, the runners can advance at their own risk.
Head-first slides are not allowed, except in the occasion of a player returning to a base to avoid a pickoff.

A pitcher must record 3 outs or face 3 batters to qualify as a pitching appearance.
If a pitcher comes in and faces only one batter or pitches only one pitch that is still considered an inning for that pitcher, although the pitcher must face at least 3 batters or record three outs for it to be considered an official appearance.
A minimum of 4 pitchers must be used in each game and each of the 4 pitchers must record three outs or face at least three batters.
