THE BAT Projection System by Derek Carty

Special Early Bird Season Pass price — only $199.99 for the entire season

Derek Carty has developed THE BAT over the past 10 years and 10,000+ 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 density and umpires to give you an edge on the competition. When tested, THE BAT proved even more accurate than Vegas and was the Most Accurate Season-Long Projection System of 2018! Plus, it works with RotoGrinders’ LineupHQ, helping you build your ideal lineups for both cash games and GPPs!
