what's the worst record in major league history
List of worst Major League Baseball season records The 1899 Cleveland Spiders own the worst single-season record of all time (minimum 120 games) and for all eras, finishing at 20–134 (.130 percentage) in the final year of the National League's 12-team era in the 1890s; for comparison, this projects to 21–141 under the current 162-game schedule, and Pythagorean expectation based on the Spiders' results and the current 162-game schedule predicts a record of 25–137.
List of Major League Baseball longest winning streaks The 1916 New York Giants hold the record for the longest unbeaten streak in MLB history at 26, with a tie in-between the 14th and 15th win. The record for the longest winning streak by an American League team is held by the 2017 Cleveland Indians at 22. The Chicago Cubs franchise has won 21 games twice, once in 1880 when they were the Chicago White Stockings and once in 1935.
