Note: Daily data in early seasons can be incomplete and will differ from end of year results due to possible missing games, unknown allocation of unearned runs, scorekeeper changes/disputes, etc. The sum of all changes impact league wide averages that WAA calculations depend upon for all players. The end of year Rank/WAA record is correct.
