MLB Worst Record Odds: Who Will Finish With Fewest Wins in 2026?

Coming off their worst season in franchise history, the Colorado Rockies are the betting favorites to finish with MLB’s worst record during the 2026 campaign.

The Rockies went 43-119 in 2025, finishing 13 games behind the Chicago White Sox. It marked the third straight year of triple-digit defeats for the Rockies, but the first time they’ve lost more than 103 games since becoming a franchise in 1993.

While it makes sense that Colorado has the best odds to post the fewest wins again, this market hasn’t gone according to plan in recent seasons.

Which MLB Team Will Record the Fewest Wins in 2026?

Per the updated MLB betting odds, the Rockies are huge favorites to post the worst regular-season record in 2026. At -400, they have an implied probability of 80%.

Although the Rockies are the worst team in baseball, I’m not sure these odds are completely fair given the recent volatility of this market. It’s difficult to be historically bad for multiple years in a row, which has been demonstrated of late.

Entering the 2025 season, the White Sox were -200 favorites to post the worst record after finishing with a 121-loss season the prior year. The Rockies came through instead at +200.

In 2024, the Athletics opened as a +150 favorite to finish with the worst record after losing 112 games in 2023. They went on to win 19 more games in 2024, while the White Sox delivered in this market at +400.

Despite all that, the Rockies deserve to be the favorites to post the worst record. They might have a worse team on paper as they transition to a new era under Paul DePodesta, who returned to baseball after 10 years away to become the Rockies’ president of baseball operations.

However, if the Rockies return to being a typical bad team, that could make the worst-record race more competitive.

PECOTA’s projections are calling for that, forecasting 60.8 wins for the Rockies. Those same projections have four other teams finishing with fewer than 70 wins.

If that happens, I see there being plenty of value in taking shots elsewhere in this market. With that in mind, my favorite options are the Washington Nationals (+600) and the Los Angeles Angels (+1600).

PECOTA projects 65.7 wins for the Angels and 67 victories for the Nationals. They both project as bottom feeders in their respective divisions. They both could be motivated to sell off key pieces at the trade deadline.

The Nationals haven’t lost more than 107 games since moving from Montreal in 2005, but they have averaged 96.4 defeats over the last five years and leaned further into the rebuild this past offseason.

The Angels, meanwhile, might be better off by finally choosing to bottom out, as they haven’t made the playoffs since 2014.

Either team would be a surprise compared to Colorado, but this market hasn’t been very chalky of late.
