High Quality Content by WIKIPEDIA articles! PECOTA, an acronym for Player Empirical Comparison and Optimization Test Algorithm, is a sabermetric system for forecasting Major League Baseball player performance. The word is a backronym based on the name of journeyman major league player Bill Pecota, who with a lifetime batting average of .249 is perhaps representative of the typical PECOTA entry. PECOTA was developed by Nate Silver in 2002-2003 and introduced to the public in the book Baseball Prospectus 2003.Baseball Prospectus (BP) has owned PECOTA since 2003; Silver managed PECOTA from 2003 to 2009. He was responsible for the PECOTA projections for the 2003—2009 baseball seasons. Beginning in Spring 2009, BP assumed responsibility for producing the annual forecasts. The first baseball season for which Silver played no role in producing the PECOTA projections was 2010.
