The Braves were a .500 team in their first few years in Atlanta – 85–77 in 1966, 77–85 in 1967, and 81–81 in 1968. The 1967 season was the club's first losing campaign since 1952, its last year in Boston. In 1969, with the onset of divisional play, the Braves won the first-ever National League West pennant, but were swept in three games by the "Miracle Mets" in the inaugural National League Championship Series. Atlanta would not be a factor in the division in the next decade, posting only two winning seasons between 1970 and 1981 – in some cases fielding squads as bad as the worst Boston teams.
