Seattle Mariners 2019: A Baseball Companion

Baseball Prospectus is an organization that aims to democratize the knowledge often confined to major-league front offices through insightful analysis of every aspect of the game of baseball. As an editorial hub, BP's team of writers covers topics ranging from contemporary analyses of the game to historical assessments using modern understanding and statistics. These efforts are augmented by a prospect team comprised of evaluators who deliver reports and rankings based on in-person looks at minor league players and a fantasy team comprised of writers who regularly compete in and win major industry leagues each season. BP's industry-leading stats team launches proprietary statistics, updates and manages the PECOTA projection system, supports editorial needs, and even provides data consulting and management for many pro organizations. It's no surprise that Baseball Prospectus has served as a training ground for dozens of team employees, including several key decision makers in baseball operations. As a whole, Baseball Prospectus provides insight into the game for the common fan that is typically relegated to the top levels of the front office.
