Baseball Think Factory

Baseball Think Factory, abbreviated as BTF or BBTF, is a sabermetrically-oriented baseball web site that features the day's prominent news stories in baseball, with original content contributed by SABR members such as Dan Szymborski. The site was previously branded as Baseball Primer, and was created in 2001 by the founders of Baseball-Reference. A number of contributors have gone on to work for Major League Baseball front offices, including Voros McCracken, Carlos Gomez, and Tom Tango. Bill James' Baseball Abstract books published in the 1980s are widely considered to be the modern predecessor to websites using sabermetrics such as baseballthinkfactory and baseballprospectus.
