During the 1969 season, Santo became known for performing a heel click after a game on June 22, 1969, against the Montreal Expos. Going into the bottom of the ninth inning, the Expos were leading 6���3. With one out, second baseman Paul Popovich hit a single, and moved up to second base after another single by left fielder Billy Williams. Although Santo grounded out for the second out, Popovich and Williams each moved up a base. Then a future Baseball Hall of Fame inductee, first baseman Ernie Banks, singled to bring home Williams and Popovich and bring the Cubs within a run. Rick Bladt substituted as a pinch-runner for Banks. That set it up for Cubs right fielder Jim Hickman, who hit a two-run walk-off home run to win the game, 7���6. When Hickman reached home plate, Santo was so excited that after congratulating him by bear hugging and pounding him on his head, Santo ran down the third base line and jumped three times, clicking his heels on each jump
