The 2025 Major League Baseball(MLB) season is leaving a bitter mark for the Colorado Rockies and Chicago White Sox. Both franchises, historically competitive at different times, now find themselves on the verge of breaking negative records that no one wants to reach. Colorado (4-21 record, .160 percentage) and Chicago (6-20, .231 percentage) are fighting not only to climb out of the bottom of their respective divisions, but to avoid going down in the MLB history books as two of the worst teams of all time.
While the White Sox face the Athletics in Sacramento, the Rockies struggle at home against the Cincinnati Reds. Both series clearly show the lack of consistency in both teams, with painful losses in the late innings reflecting their deep deficiencies.
The White Sox

In 2024, the White Sox had already set an all-time mark by closing the season with a dreadful 41-121.
Worst winning percentage (.253) in the modern era (since 1901).
They even surpassed the mythical 1962 New York Mets (40-120, .250).

Now, in 2025, the picture is not much different.
With its current performance, Chicago threatens to repeat a 100+ loss season.
It would be devastating for a franchise struggling to rebuild its competitive identity.
In their most recent series, they fell to Oakland after blowing a ninth-inning opportunity, proving that mental mistakes continue to cost them close games.
The Rockies

The Rockies’ situation is even more alarming than that of the White Sox.
With a winning percentage of just .160, they project to finish the season with less than 30 wins.
This is unprecedented in the modern MLB era.
The inevitable comparison is to the 1899 Cleveland Spiders, the worst team in league history, which closed with an infamous 20-134 (.130) record.
The Spiders, notorious for losing 24 consecutive games and winning just 11 away games, represent the standard of misery that now haunts Colorado.
With four straight losses and a 1-9 record in their last 10 games, the Rockies face an urgent need for changes to avoid falling into the record books in the worst way.
