* - Disclaimer & Completeness Note

* Many detailed statistics are based on play-by-play accounts accumulated by Retrosheet. These totals may be incomplete (3.6% of all plays from 1915 to 1972 are missing or have incomplete accounts, click link for year and team summary of data completeness) for some players prior to 1973 and even complete seasons may not match the official totals due to errors in both the official totals and the play-by-play accounts. Pre-1954 seasons have a substantial numbers of games missing play-by-play accounts and should be viewed as essentially incomplete.
