Thanks to the great folks at RetroSheet we are now able to launch box scores and game logs for 1916 and 1917 and additional play-by-play for 1945-1947 along with additional games found here and there for 1948-1973.
For a full list of our data coverage, check out our Data Coverage page.
I have yet to re-run the full site, so the 1916 A's and 1917 retirees will not yet have links to splits or gamelogs, but that should happen later today or tomorrow.
Box Score Directory (1916-2012)
Note: RetroSheet also has 1915 AL and NL box scores, but not yet Federal League boxes. Given our setup we require a full set to be available before we can publish a year's worth of box scores.
