Baseball reference dating

It’s got managers, birthdates, awards, all-star games, and other good stuff. It’s the result of a small army of volunteers, combing historical sources to try to re-create the play-by-play of every game in baseball history and digitizing it for download and analysis. Rice grounded out (shortstop to first); Presko popped to first in foul territory; Hemus popped to first in foul territory.) You can also see the entire career of any player, game by game.

The result of literally tens of thousands of hours of volunteer labor, Retrosheet is the greatest sabermetric resource ever.

There are two main sources of raw data: the Lahman Database and Retrosheet.

The Lahman Database can be obtained for free at seanlahman.com/baseball-archive/statistics, the website of its creator, Sean Lahman.

Not only do you get the regular Bill-Terry’s-batting-average data, but you also get a large selection of sabermetric stats, breakdowns by tens of different criteria (left/right, day/night, April/September, and so on), and the ability to manipulate the data in ways that other websites don’t allow. Want to know Joe Morgan’s longest consecutive streak of games where he came to the plate at least twice? (If you want the details, you have to subscribe, but the overwhelming majority of the information on the site can be had for free.) For those of us who want to do more complicated things, Baseball Reference, awesome as it is, just isn’t enough.

We need the raw data on our own computers, so we can manipulate it in ways that B-R never thought of.

If you’re familiar with Access and with SQL database queries, you know how convenient it is to use it to do powerful, specific data searches quickly.

(If you’re not familiar with SQL, there have been a few tutorials on sabermetric sites recently.) Anyway, the Lahman Database has every player’s standard batting and pitching line for every year.

But if you wanted more esoteric statistics, like Joe Morgan’s career performance with the bases loaded, you were out of luck.
