He also officiated in the National League Championship Series in 1971 and 1975, serving as crew chief in 1971, and in the three-game playoff to determine the NL champion in 1959. He also worked in the All-Star Game in 1954, 1958, 1960 (both games) and 1969, calling balls and strikes for the second half of the second 1960 game. During a game in the 1962 season, he discovered that the Giants (by now in San Francisco) were having their groundskeepers water down the Candlestick Park infield to slow down the Los Angeles Dodgers' Maury Wills; Gorman stopped the game for an hour and a half to allow the field to dry out.
