Over the course of 145 seasons (from 1876 to 2023, excluding 1981, 1994, and 2020), 119 teams have won 100 or more games in a single Major League Baseball season. While this makes the feat a relatively common occurrence, the 100-win threshold remains the hallmark of the best teams in a given season.
The franchise with the most 100-win seasons is the New York Yankees, who have done so 21 times, with the Los Angeles Dodgers being second with 11 occasions. Sixty different managers have led a team to a 100-win season, with only one occasion where a 100-win team was led by multiple managers. Twenty-four managers have led a franchise to two or more 100-win seasons; Sparky Anderson, Whitey Herzog, Tony La Russa, Dusty Baker and Buck Showalter are the only managers to have led multiple franchises to a 100-win season. Joe McCarthy and Bobby Cox have the most 100-win seasons by a manager with six. Seven of the 30 major league franchises have never recorded a season with 100 wins.[a] Among rookie managers, seven have accomplished 100 wins in their inaugural season, with the first being Mickey Cochrane in 1934 and the last being Rocco Baldelli in 2019.[1] 68 of the 116 100-win teams have advanced to the World Series (.586), with 38 of them going on to win the Series (for a percentage of .559), while 23 teams that have won 100 games have lost in the first round of the postseason, with 22 being in the Division Series and one being in the Wild Card Series (introduced in 2022 full-time).
Listed below are the Major League Baseball franchises that have had seasons with 100 or more wins.
