The Giants play at Candlestick Park, July 1971, with upper deck expansion in progress.
The Giants battled their arch rival, the Los Angeles Dodgers, throughout the season for the NL West Division lead. The Giants led by 8.5 games on September 1. In mid September the Dodgers won 8 in a row, including 5 over the Giants to narrow the gap to one game. On the final day of the season, rookie Dave Kingman homered, leading the Giants to a win over the San Diego Padres to take the division crown, allowing Juan Marichal, Willie Mays, and Willie McCovey to play in the post season for the last time together.
September 5, 1971: In a game against the Giants, J.R. Richard of the Houston Astros struck out 15 batters in his very first game, tying a Major League record first set by Karl Spooner.
