College basketball once banned dunking because of Lew Alcindor (Kareem Abdul-Jabbar). What will baseball do with Pat Venditte?

For those not so familiar with baseball: Left-handed hitters generally hit better against right-handed pitchers, and right-handed hitters generally hit better against left-handed pitchers. Being able to throw with both arms gives the pitcher a distinct advantage by allowing him or make their decision about which arm to use after the batter steps into the box. Now, throw a switch-hitter into the mix, and you get the "Ring Around the Rosie" game shown above.

[UPDATE]: It turns out there is a rule that takes this scenario into account, and the umps ruled incorrectly. The pitcher has to declare which arm he's going to throw with and cannot change before the end of the at-bat. The batter can change in between pitches.
