In the 1975 season, Cincinnati clinched the NL West with 108 victories, then swept the Pittsburgh Pirates in three games to win the NL pennant. In the World Series, the Boston Red Sox were the opponents. After splitting the first four games, the Reds took Game 5. After a three-day rain delay, the two teams met in Game 6, one of the most memorable baseball games ever played and considered by many to be the best World Series game ever. The Reds were ahead 6–3 with 5 outs left, when the Red Sox tied the game on former Red Bernie Carbo's three-run home run. It was Carbo's second pinch-hit three-run homer in the series. After a few close-calls either way, Carlton Fisk hit a dramatic 12th inning home run off the foul pole in left field to give the Red Sox a 7–6 win and force a deciding Game 7. Cincinnati prevailed the next day when Morgan's RBI single won Game 7 and gave the Reds their first championship in 35 years. The Reds have not lost a World Series game since Carlton Fisk's home run, a span of 9 straight wins.
