Retrosheet's Second Semi-Annual Release of 2025

Retrosheet is pleased to announce its second semi-annual update of 2025. Major thanks go out to Joe Callahan for generating the "Games/People/Parks" portion of the website and to Rob Wood for his significant efforts in helping to prepare the data presented here.

What's New in This Release

• 2025 season The 2025 season is now available. Thanks to MLB for providing the data here and thanks to Ted Turocy for doing the heavy lifting in converting it to Retrosheet's event-file format. Event and box-score files are available for download for all 2025 regular-season and postseason games as well as the 2025 All-star game.


• 1910 Event files, including some deduced files, are now available for all of the 1910 American and National League seasons. Special thanks to Rob Wood for leading this effort and thanks to our team of deducers: Cliff Blau, Jim Herdman, Dave Smith, and Rob Wood.


• 1898 Box-score files are now available for the 1898 National League season. Thanks to Dick Cramer, Cliff Blau, and Pete Palmer for their help with 19th-century seasons.


• Negro Leagues This release includes the 1935 Negro League season. Retrosheet has identified 342 Negro League games played in the 1935 season and has play-by-play accounts for 96 of these games (91 of which are deduced). This brings the total number of Negro League games in Retrosheet's collection to 7,681. Retrosheet has line scores and batteries for 6,052 of these games, box-score level detail for 4,248 of these games, and (mostly deduced) play-by-play accounts for 1,877 of these games. Thanks to Tom Barnett, Alan Cohen, Dean Esgrow, Laura Peebles, and Wes Tervo for their help compiling these games.


• 1911 - 1920 seasons Since our last update, Rob Wood undertook a careful review of previously-released seasons to incorporate additional information from newspapers that are newly available online since these seasons were originally compiled. Starting with the 1911 season and moving forward, Rob has completed significant updates to the 1911 - 1920 seasons. In addition, home run data were updated to identify inside-the-park home runs hit during the 1911 - 1922 seasons. Thanks to Bill Way for compiling these data. The 1911 season has also been updated to more accurately identify unearned runs. Thanks to Rob Wood for initiating this project.


• Individual game updates In addition to all of the above updates, Retrosheet has updated our event files for 230 games across other seasons (1921 - 2024) through the discovery of new scorecards, new newspaper sources, and a growing number of radio and television accounts that are being made available online. In some cases, edits to games are quite small: an added attendance figure, a clarification of one or two plays. But these improvements include the promotion of 21 deduced files to full event files, the removal of 47 games from our 'most wanted' lists, and the addition of pitch data for 30 games. Special thanks to Mike Cantor, Bill Ivimey, Bill Way, Jay Wigley, Rob Wood, Bob Yahr, and others for their help in this work. A detailed description of most of these improvements can be found here (this list does not include detailed updates for the 1910 - 1920 and 2025 seasons, or Negro League games, and may be incomplete).


• Download all of Retrosheet's traditional data (event files, box-score files, game logs, etc.) here. (326Mb zip file)


• Download a set of .csv files providing daily logs for teams and players as well as fully parsed play-by-play data here (710Mb zip file).

• Parsed Play-by-Play Data. Several additional fields have been added to the parsed play-by-play files available for download based on user feedback. The contents of these files are described here.


• Event-file parsing tools: Retrosheet has updated its parsing tools, BEVENT.EXE and BGAME.EXE. These tools are described and can be downloaded from here. The latest updates to BEVENT and BGAME will be necessary to handle a couple of unusual plays that happened during the 2025 season.


• Using Retrosheet Data: Retrosheet continues to add sources to its page listings, Resources for Using Retrosheet Data and Websites Using Retrosheet Data, as we become aware of them. If you have or know of a website that you think should be added to either of these pages, please reach out to me at tthress@retrosheet.org.


• Research Papers: Retrosheet posts original research using our data. In 2025, Retrosheet has added six new research articles by five authors: Tom Conlon, Brien Kocsis, Herm Krabbenhoft, Mike O'Brien, and Steve Scott. If you have original research that you would like to publish on our website, please reach out to me at tthress@retrosheet.org. Our only requirement is that the research use Retrosheet data.


• Charlie Pavitt has compiled an extensive bibliography of sabermetric papers which use Retrosheet data. The most recent version of Charlie's research was updated on October 31, 2025, and can be found here.


• Finally, Retrosheet has added several entries on additional pages since our last major release to add and update historical and 2025 data. These include various Outstanding Feats, Milestones, and Noteworthy Events. Thanks to Cliff Blau, Bruce Fleming, Dave Smith, Rob Wood, and others for helping to update these lists.

If anyone knows of any additions to any of our pages, please reach out to me at tthress@retrosheet.org.
