OBR Ambidexterous pitcher

[SAump]

(2) The batter may leave the batter’s box and the dirt area surrounding home plate when “Time” is called for the purpose of
(i) making a substitution; or
(ii) a conference by either team.

(2) (i) Batter may switch from one box to another during one at-bat. By rule, he must call time first and allow the defense fair notice. Defense may also acknowledge an unannounced substitution by allowing batter into other box and delivering a pitch. If defense complains about the switch, the UIC should determine whether to allow it or not. UIC, according to rules, customs and traditions; should not allow game delay or unsportmanship behavior to occur. Offense will be warned to "STAY in BOX" and a strike will be awarded after each occurence.
