To assure uniformity in establishing the batting, pitching and fielding
championships of professional leagues, such champions shall meet the following
minimum performance standards:
(a) The individual batting, slugging or on-base percentage champion shall be the
player with the highest batting average, slugging percentage or on-base percentage,
as the case may be, provided the player is credited with as many or more total
appearances at the plate in league championship games as the number of games
scheduled for each club in his club’s league that season, multiplied by 3.1 in the
case of a Major League player and by 2.7 in the case of a National Association
player. Total appearances at the plate shall include official times at bat, plus bases
on balls, times hit by pitcher, sacrifice hits, sacrifice flies and times awarded first
base because of interference or obstruction.
Notwithstanding the foregoing
requirement of minimum appearances at the plate, any player with fewer than the
required number of plate appearances whose average would be the highest, if he
were charged with the required number of plate appearances shall be awarded the
batting, slugging or on-base percentage championship, as the case may be.
Rule 10.22(a) Comment: For example, if a Major League schedules 162 games for each
club, 502 plate appearances qualify (162 times 3.1 equals 502) a player for a batting, slugging or onbase
percentage championship. If a National Association league schedules 140 games for each club,
378 plate appearances qualify (140 times 2.7 equals 378) a player for a batting, slugging or on-base
percentage championship. Fractions of a plate appearance are to be rounded up or down to the closest
whole number. For example, 162 times 3.1 equals 502.2, which is rounded down to a requirement
