Munson batted .308 with 100 RBI in 1977, giving him three consecutive seasons batting .300 or better with 100 or more RBI each year. He was the first catcher to accomplish the feat in three consecutive years since Yankee Hall of Famer Bill Dickey's four straight seasons from 1936-1939, matched only by Mike Piazza since (1996–1998). The Yankees repeated as American League Champions, and faced the Los Angeles Dodgers in the World Series. Munson batted .320 with a home run and three RBI in the Yankees four games to two victory over the Dodgers. The Dodgers had stolen 114 bases during the regular season, yet Munson caught four of six potential base stealers in the first four games of the series to keep the speedy Dodgers grounded in the final two.
Munson's World Series championships in 1977 and 1978 made him only the second catcher in baseball history, at the time, to win a Rookie of the Year Award, an MVP Award, a Gold Glove Award, and a World Series title during his career. Johnny Bench had become the first catcher to win all four of these awards when he won his own World Series titles with the Reds in 1975 and 1976. Subsequently, and more recently, when Buster Posey won his first Gold Glove Award in 2016 he also joined this list of three catchers in all of baseball history to win all four awards. But as a further point on unique contributions to the game, since Posey and Munson both were named as College Baseball All-Americans based upon their collegiate baseball careers, they now share the additional distinction of being the only two Catchers in history named to an All-American Team who also own a ROY, MVP, GG, and World Series Title.
