Baseball Player Won-Lost Records



Games and Seasons for which Player Won-Lost Records are Calculated

Last updated 12/23/13

Player won-lost records are calculated using play-by-play data. The source of this play-by-play data is Retrosheet. At present, Player won-lost records are available for the following seasons. Seasons in bold are missing some games. Seasons in italics include games deduced by Retrosheet from box scores and partial play-by-play data.

1922, 1927, 1931
1938 - 1950
1951 - 1959
1960 - 1961
1962 - 1968
1969 - 1970
1971 - 1973

Most Recent Updates to Player Won-Lost records

A full update of all Player won-lost records was completed on December 23, 2013. This update incorporated all of the play-by-play data available with Retrosheet's fall release. This includes three new seasons: 2013, 1939, and 1922, the latter two of which are still missing some games, as well as the addition of play-by-play data for 340 new games for seasons for which Player won-lost records had already been calculated (1927, 1931, 1939, 1940 - 1950).

Player won-lost records were also updated for seasons for which full play-by-play data had already existed (1951 - 2012); changes to Player won-lost records for these seasons should generally be quite minor.

For seasons with missing data, teams are missing the following numbers of games. Team records in missing games are shown in parentheses (W-L-T).
