The 2024 Chicago White Sox had the most losses, 121, of any Major League Baseball team in modern-day history finishing the season 80 games below .500 and 51.5 games out of first place.
They scored the fewest runs of any team in the past 50 years and their run differential was the third worst in MLB history. Plus they were lowest in the league in home runs, RBIs, and OPS, had the second worst batting average, and third worst ERA despite having a $133M payroll, 18th in the league. Their payroll exceeded 11 teams including several playoff teams: Royals, Brewers, Orioles, and Guardians. They had a 0-88 record when trailing after 8 innings as well as a MLB-high of 51 blown lead losses and 37 blown saves (a 35% save percentage compared to the MLB average of 63%).
They set a record for the quickest assurance of a losing season by losing 82 of their first 109 games, surpassing the 2003 Detroit Tigers, who lost 82 of their first 111 games. Meanwhile, starting pitcher Chris Flexen set the MLB record of 20 consecutive starts where his team went on to lose.
They lost at least four straight games 14 separate times this season, headlined by an American League-tying 21 game losing streak and a 14 game losing streak. They started the season with four consecutive losing streaks, each longer than the last. They lost the first four games of the season, then lost five straight, then six straight, then seven in a row. Each streak was separated by one victory.
