1991 Atlanta Braves Season
In 1991, the Atlanta Braves became the first team in the National League to go from last place one year to first place the next. This feat was also accomplished by the 1991 Minnesota Twins. The last Major League Baseball team to accomplish this was the 1890 Louisville Colonels of the American Association.
The Braves had a last place finish in 1990 but managed to overtake the Los Angeles Dodgers for first place in the National League West clinching the division on the next to the last day of the regular season.
