 Passage 3:On the mound, the Reds relied on left-handers Don Gullett and Fred Norman to pacify the Yankee hitters in Games 1 and 2, respectively. Gullett had come back from a mid-season injury to start Game 1 but had to leave the game in the eighth inning due to a twisted ankle while Norman out-pitched ace Hunter in Game 2. Game 3 in New York pitted effective 1976 NL Rookie of the Year Pat Zachry for the Reds against newly acquired Yankee, Dock Ellis. Ellis only lasted innings, exiting in the fourth after a home run by Driessen. Game 4 was delayed a day due to rain, but the Reds were ready for the sweep. Bench's two-run home run gave the Reds a 3–1 lead. In the bottom of the eighth, a frustrated Billy Martin threw a baseball from the dugout onto the field towards home plate umpire Bill Deegan, causing his ejection from the game. In the ninth, Bench's second home run followed by back-to-back doubles by César Gerónimo and Dave Concepción made the score 7–2 and essentially blew the game open. The Cincinnati Reds outscored the New York Yankees, 22–8, and became the first NL team to repeat as World Champions since the 1921–1922 New York Giants. The Reds did not make a single offensive or defensive substitution (save pitching changes) during the entire series. Bench would claim the MVP of the series hitting .533 with two home runs and six runs batted in. His catching counterpart, Thurman Munson, had nine hits, all singles, and a .529 batting average.
