Book excerpt: From the vaudeville gyrations of New York Giants star pitchers Rube Marquard and Christy Mathewson, to Gene Kelly and Frank Sinatra as hoofing infielders in Take Me Out to the Ball Game, to the stage and screen versions of Damn Yankees, the connection between baseball and dance is an intimate, perhaps surprising one. Covering more than a century of dancing ballplayers and baseball-inspired dance, this entertaining study examines the connection in film and television, in theatrical productions and in choreography created for some of the greatest dancers and dance companies in the world.
