Curran's title summarizes the dramatic hitting surge of the 1920s, as swelling batting averages and skyrocketing home run totals changed baseball forever. Curran, author of Mitts: A Celebration of the Art of Fielding ( LJ 6/1/85), describes the influence of the livelier baseball and the emergence of Babe Ruth as a slugger, as the game shifted from tight defensive play to wide open offensive play. Recording the hitting achievements of Ruth, Ty Cobb, Lou Gehrig, Rogers Hornsby, and others, Curran recaps the decade's pennant chases and World Series. Somewhat paralleling William B. Mead's Two Spectacular Seasons ( LJ 2/1/90), this is worthwhile for popular sports collections.-- Morey Berger, Monmouth Cty . Lib., Manalapan, N.J.
