Ejections are a common feature of baseball with some confrontations being especially memorable. The first systematic compilation
of ejection details was that of Doug Pappas. David Vincent wrote a brief history of ejections in a paper that is on the research page
of the Retrosheet website: (Ejection History). The ejection database is now maintained by Retrosheet.

David noted that umpires only gained the authority to remove unruly players, coaches, and managers in 1889. Prior to that time,
the only penalties for misbehavior were monetary fines and possibly suspensions. David Smith analyzed patterns of ejections
for SABR50. That presentation is also on the Retrosheet research page (Ejection Patterns).

As a prelude to the SABR50 paper, the Retrosheet compilation of ejections was expanded, put into standard format and proofed
for accuracy. Rob Wood was instrumental in these enhancements.

Retrosheet now has detailed information on nearly 18,000 ejections and our full data base is available for download here: Ejection Data,.
This chronologiclal list is a standard text file suitable for import into spreadsheets or database programs or for use in programs
written by interested individuals.

Each record in this file has the following fields.
