View splits adjusted to be per 162 games or 650 PAs
First column (I) indicates when a split may be incomplete due to missing play-by-play data. For all seasons after 1968, the play-by-play data is 100% complete (year-by-year coverage). Prior to 1913 for AL and 1912 for NL, many games are missing earned runs since they were not an official stat at that time.
