THE BAT is the brainchild of Derek Carty, who spent years honing his statistical chops as the Fantasy Manager for Baseball Prospectus and The Hardball Times (now part of FanGraphs), working alongside and learning from some of the greatest sabermetric minds in the game, many of whom have gone on to work in MLB front offices.

THE BAT starts as a comprehensive projection system in the vein of PECOTA, Oliver, or ZiPS and then adds additional layers for daily players. It considers all of the factors relevant on a daily basis:

• Opposing Hitter/Pitcher
• Ballpark
• Weather
• Umpires
• Catchers
• Platoon Splits (Hitter/Pitcher/Park/Umpire/Catcher)
• Role
• Lineup Position
• Quality of Surrounding Lineup
• Bullpen
• League
• Home Field Advantage
• And more...

While already the most comprehensive daily model on the market, THE BAT is constantly being added to and upgraded with additional contextual factors and under-the-hood upgrades. Underscoring everything is meticulous methodology and statistical processes Carty learned and developed in his years working for the premier sabermetric destinations on the web.
