Casey Blake, American baseball player
William Casey Blake (born August 23, 1973) is an American former professional baseball third baseman. He played in Major League Baseball (MLB) for the Toronto Blue Jays, Minnesota Twins, Baltimore Orioles, Cleveland Indians, and Los Angeles Dodgers. He had alternated between playing at third base and first base before becoming a full-time third baseman with the Indians. In 2005, Blake moved to right field to accommodate the Indians' signing of third baseman Aaron Boone, and stayed there for two seasons before moving back to third base.

Blake was drafted twice prior to signing with the Blue Jays: in 1992, he was selected during the 11th round by the Philadelphia Phillies and in 1995, he was taken by the New York Yankees during the 45th round.
