Lou Gehrig also saw Ruth point. In 1992, a Cub fan unearthed a home video taken by his father at the 1932 World Series. The video showed Ruth pointing 4 times, including two distinct gestures prior to the pitch. The Sporting News ran these pictures in an issue later that year. Ruth may or may not have pointed.
Nobody really knows.
Golenbock too easily dismisses one of baseball's most interesting tales. Since Gabby Hartnett cracked his famous Homer in the Gloamin' in 1938, the Cubs had only won one other National league pennant. They won that in 1945, on the shoulders of Philli-Buck Cavaretta and Hank Borowy. Most able-bodied ballplayers were finishing their military obligations when the Cubs won their last pennant. The Cubs had such a long string of failures after Phil Wrigley died.
