The Dodgers lost 10 of their final 13 games from September 16 to 30, while the Giants lost just 6 over the same span. While the schedule says the Dodgers lost the pennant in late September/early October, it was probably lost on July 17 in Cincinnati. That is when star left-hander Sandy Koufax left his start against the Reds in the first inning with a bruised tendon on his finger. Koufax would miss 58 games and approximately 13 starts due to the injury. At the time, Koufax was 14-5 with a league-best 2.15 ERA. The desperate Dodgers brought Koufax back on Sept. 21 when he was clearly not ready. He started three games, but lasted a total of 6 2/3 innings and gave up nine runs and went 0-2 along with a no-decision. However, with seven games remaining the Dodgers were still ahead in the league by four games, and later held a two-game lead with three left to play. They entered their final game with a one-game lead over the Giants, but fell 1–0 to the St. Louis Cardinals. Meanwhile, the Giants won 2–1 over the Houston Colt .45's, after an eighth-inning home run by Willie Mays. These results left the Dodgers and Giants tied in the league at 101–61, necessitating a tie-breaker to decide the NL pennant. The three-game tiebreaker series was considered part of the regular season for statistical purposes. The Giants won game one, while the Dodgers took game two. The Giants then took game three to capture the NL pennant.
