Derek Carty's THE BAT Projection System

Derek Carty has developed THE BAT over the past seven years and ten thousand hours, using skills and methods developed from his time in the sabermetric community working with some of the best baseball minds in the world, many of whom are now making decisions for Major League clubs. THE BAT incorporates all the necessary basics, like park factors and platoon splits, plus many lesser-considered factors like air pressure and umpires to give you an edge up on the competition. And it works with RotoGrinders’ Lineup Builder, helping you build your ideal lineups for both cash games and GPPs. Read more about what THE BAT incorporates here.
