The Colorado Rockies pulled off the unthinkable last night -- they won a game and are officially not the worst team of all time. The 2025 Rockies will instead be remembered for their historically bad run differential (unless of course they somehow start to just pummel opposing teams the rest of the season), as no team in the history of baseball has a run differential that's worse than Colorado's current mark of -403.
The 2025 Rockies are sitting pretty with their 42-112 record -- the 2024 Chicago White Sox are still the worst team in the modern era (from 1901-on) thanks to their 41-121 record.
