Switch Hitter vs Switch Pitcher

When are the Yankees going to promote this sideshow??

Apparently, baseball invented a new rule because of him. It reads:

• The pitcher must visually indicate to the umpire, batter and runner(s) which way he will begin pitching to the batter. Engaging the rubber with the glove on a particular hand is considered a definitive commitment to which arm he will throw with. The batter will then choose which side of the plate he will bat from.

• 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. For example, if the pitcher changes from right-handed to left-handed and the batter then changes batter’s boxes, each player must remain that way for the duration of that at-bat (unless the offensive team substitutes a pinch hitter, and then each player may again “switch” one time).

• Any switch (by either the pitcher or the batter) must be clearly indicated to the umpire. There will be no warm-up pitches during the change of arms.

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