Nate Silver, American journalist and statistician, developed PECOTA

Nathaniel Read Silver is an American statistician, political analyst, author, sports gambler, and poker player who analyzes baseball, basketball and elections. He is the founder of FiveThirtyEight and held the position of editor-in-chief there, along with being a special correspondent for ABC News until May 2023. Since departing FiveThirtyEight, Silver has been publishing in his online newsletter Silver Bulletin and serves as an advisor to Polymarket.

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. Beginning in Spring 2009, BP assumed responsibility for producing the annual forecasts, making 2010 the first baseball season for which Silver played no role in producing PECOTA projections.
