In the 1972 National League Championship Series, the defending World Series Champion Pittsburgh Pirates faced the Cincinnati Reds. In Game 5, with both teams tied at two games apiece, the Pirates led 3–2 in the bottom of the ninth inning and were three outs away from advancing to the World Series. But Pirates closer Dave Giusti unraveled. He surrendered a game-tying home run to Johnny Bench before allowing back-to-back singles to Tony Pérez and Denis Menke before being relieved by Bob Moose, who almost worked out of the jam by recording two outs. But with pinch-hitter Hal McRae at the plate, Moose lost his footing and uncorked a wild pitch sending George Foster, who was pinch running for Pérez, home with the pennant-clinching run and setting off a massive celebration at Riverfront Stadium.
