The 1977 postseason schedule started on Tuesday after starting on Saturday from 1969 to 1976. Major League Baseball began a pattern where one League Championship Series started on Tuesday and contained an off-day while the other LCS started on Wednesday with no off-day. NBC used three different announcer crews (Joe Garagiola and Tony Kubek, Jim Simpson and Maury Wills, and Dick Enberg and Don Drysdale) on the 1977 LCS.
