Youkilis was at home at third base when playing the field, but it was his plate discipline that made him famous within the baseball world. In the book "Moneyball," written by Michael Lewis in 2003, Oakland general manager Billy Beane referred to Youkilis as the "Greek god of walks." The book ushered in a new era in baseball statistics that helped make players like Youkilis, who weren't traditional stars, more valuable because of their patience at the plate. Despite the promise of future success, Youkilis stayed in the dugout during the 2004 World Series. His departure leaves only David Ortiz as an active Red Sox from that historic squad.
