About Bill James
George William James is an American baseball writer, historian, and statistician whose work has been widely influential. Since 1977, James has written more than two dozen books about baseball history and statistics. His approach, which he named sabermetrics after the Society for American Baseball Research (SABR), scientifically analyzes and studies baseball, often through the use of statistical data, in an attempt to determine why teams win and lose. James's publisher agreed to distribute two annuals of essays and data—the 1987 and 1988 editions of Bill James Presents The Great American Baseball Statbook (though only the first of these featured writing by James). In 2003, James was hired as senior advisor on Baseball Operations for the Boston Red Sox and worked for the team for 17 years during which they won four World Series championships. The first three editions of the Baseball Abstract garnered respect for James's work, including a very favorable review by Daniel Okrent in Sports Illustrated. Among the statistical innovations attributable to James are: Runs created.
