The league president shall appoint an official scorer for each league. The scorer shall have sole authority to make all decisions involving judgment, such as whether a batter's advance to first base is the result of a hit or an error. The scorer shall communicate such decisions to the press by hand signals or over the loudspeaker system and shall advise the announcer of such decisions if requested. In the event of a question of eligibility of a pitcher the record of the Official Scorer shall be deemed official.
