about pitchers in baseball?

The Professional Baseball Umpire Corporation (PBUC) has realease a rule regarding ambidextrous pitchers.

The pitcher must visually indicate to the umpire, batter and runner(s) which way he will begin pitching to the batter.

The pitcher must throw one pitch to the batter before any “switch” by either player is allowed.

After one pitch is thrown, the pitcher and batter may each change positions one time per at-bat.

Any switch (by either the pitcher or the batter) must be clearly indicated to the umpire.

If an injury occurs the pitcher may change arms but not use that arm again during the remainder of the game.

Well, switch pitchers are Rare, but n the Yankees farm system they have a guy named Pat Venditte, and he is also a switch pitcher. Pat Venditte is the only known professional switch pitcher. The batter has to stay at the same side of the plate the whole at bat, unless there is a pitcher change. the batter has the first step in, and the pitcher has the last change, but the Pat venditte was pitching against a switch hitter, and both of them kept switching, until they found the rule on switching after the game.

There is actually a minor league pitcher named Pat Venditte pitching for the Staten Island Yankees. He has a glove with 6 finger slots so he can change pitching righty or lefty depending on who is coming up to bat. I don't think there is a rule as to how he has to pitch once the batter steps into the batter's box.

There is no rule debating if the pitcher can change throwing arms during batters. However, this would never happen. A batter cannot change sides though, after strike two.

Meaning If a batter starts lefty and after two strikes he cannot switch sides.
