When was the last time each MLB team lost 100 games?

With the 2026 MLB season underway, here’s a look at the last time each team across the league reached the futile mark of 100 losses in a season.

As baseball is back in action with the first series of the year wrapping on Sunday across the league, fans of all 30 teams are holding on to some degree of hopefulness that this can indeed be the year.

Of course, there’s a decent range of outcomes teams can be faced with by the end of September at the conclusion of the 162-game season. A campaign with 90 or more wins is likely a postseason guarantee with the 12-team playoff format, while even finishing with a record above .500 gives a club a decent shot to find their way into October.

For clubs who entered the 2026 season with little expectation of an October berth, the benchmarks of a successful season are often different. While echelons away from a playoff berth, I don’t think you’d find any Colorado Rockies fans that would be upset with a 70-win season in 2026.

As the season progresses and teams get a better idea of what their true ceiling is for the year, teams closer to the bottom of the standings often simply try to escape whatever version of futility they’re being faced with. This can come in the form of a last-place finish in the division, which is exceptionally rare in recent memory for teams like the St. Louis Cardinals, or it could be simply trying to avoid the 100-loss mark.

For the aforementioned Rockies in 2025, it meant narrowly escaping the title of the worst team in modern MLB history, a mark set just a year earlier by the 2024 Chicago White Sox with a 41-121 season.

For clubs across the league, 100 losses in a season is meant to signify a true rock bottom for a franchise – a point where a team can only go up from, with steps often taken to start a rebuilding process by trading proven talent for young prospects.

While there’s typically only a small handful of, if any, 100-loss teams each year, it’s a fate most fanbases are familiar with confronting at least once. For the Los Angeles Angels however, a 99-loss season in 2024 remains their worst showing in franchise history – making them the only club to have never reached the mark in franchise history.

With all 30 teams looking to escape that fate this year, here’s a look at the last time each MLB team lost 100 games in a season, beginning with the most recent occurrences.
