Offseason Retrosheet Update
Thanks to our friends at Retrosheet, Baseball Reference has added Play-by-Play for 2,493 AL/NL and Federal League games from 1913 through 1968. You'll notice no mention of 1969 through 2024, because we already have Play-by-Plays for all of those games (again, thanks to Retrosheet). Via our Play-by-Play coverage map here you can see that we have Play-by-Plays for over 99% of games in every season since 1957, over 95% of games in every season since 1953, and over 75% of games since 1914. The only season since 1912 with less than 75% coverage is 1913 (68.2%). The only other AL/NL seasons under 90% since 1912 are 1944 (75.8%, 1945 (83.4%), 1943 (84.2%), 1946 (87.6%), 1949 (89.2%), 1948 (89.4%) and 1941 (89.7%).
These updates are heavily concentrated in 1914 (1,001 games) and 1915 (963 games), and we now have Play-by-Play coverage for 96% of Federal League games (the league existed for those two seasons). 1916 also has a lot of new play-by-plays (388), while 1913 (23), 1943 (21), 1945 (20) and 1944 (16) are the only other seasons in double digits.
