In 1910 auto magnate Hugh Chalmers offered an automobile to the baseball player with the highest batting average that season. What followed was a batting race unlike any before or since, between the greatest but most despised hitter, Detroit's Ty Cobb, and the American League's first superstar, Cleveland's popular Napoleon Lajoie. The Chalmers Race captures the excitement of this strange contest-one that has yet to be resolved.   The race came down to the last game of the season, igniting more interest among fans than the World Series and becoming a national obsession. Rick Huhn re-creates the drama that ensued when Cobb, thinking the prize safely his, skipped the last two games, and Lajoie suspiciously had eight hits in a doubleheader against the St. Louis Browns. Although initial counts favored Lajoie, American League president Ban Johnson, the sport's last word, announced Cobb the winner, and amid the controversy both players received cars. The Chalmers Race details a story of dubious scorekeeping and statistical systems, of performances and personalities in conflict, of accurate results coming in seventy years too late, and of a contest settled not by play on the field but by human foibles.
