After posting the careers of top home grown St. Louis Cardinals I decided to present minor leagues differently and automate this more and hopefully make it easier to find and analyze top prospects. Players with the best WAA in a minor league season are not necessarily top prospects. They may be players who can excel in the minors and not higher. More code is required to try out and implement some more and different sorts.
In the meantime here’s a fun table generated from my data model showing top 15 players in post season play who gave up the most runs due to errors. These stats were derived from modified play by play event files curated and made available by retrosheet.org. The general rule of thumb average throughout history is that an unearned run is scored for every two errors. Individual results will vary. Conclusions shouldn’t be made from this data other than these players played a lot in post season.
This type of data is part of the way this data model ranks fielding.
