Few franchises in the deadball era won as consistently or as often as the New York Giants and Philadelphia Athletics. Between them, the teams claimed 12 pennants and finished second or higher 22 times. The steady success also earned managers John McGraw and Connie Mack their reputations. It was history in the making, then, when the two Hall of Famers led their clubs into the 1913 World Series, the third and final time they went head to head for the world championship. The author provides a carefully researched account of the season-long dominance of the Giants and A's, the narrative building toward a dramatic collision in the Fall Classic.
