Chicago White Sox (-175): The Clear Favorite

The Chicago White Sox are overwhelming favorites to finish with MLB’s worst record in 2025, and for good reason. Looking at their projected roster and situation, it’s easy to see why oddsmakers have them at -175.

Their projected lineup lacks established MLB talent, with Chase Meidroth, Josh Rojas and Miguel Vargas filling key infield positions. Luis Robert Jr. remains their only true star, but even he continues to draw trade interest, meaning the team could get even weaker mid-season. Andrew Benintendi is already expected to miss Opening Day after suffering a fractured hand in spring training.

The rotation situation is equally concerning. Looking at their projected starting five (Jonathan Cannon, Davis Martin, Martín Pérez, Sean Burke, and Shane Smith), there’s a glaring lack of proven MLB production. Drew Thorpe, who might have provided some upside, is dealing with setbacks from elbow surgery and won’t be ready for the start of the season.

After consecutive disappointing seasons, the White Sox appear to be fully embracing a rebuild, making them the logical choice for this market.

Colorado Rockies (+200): Strong Value Contender

The Rockies offer excellent value at +200. According to the projections, they’re expected to go 63-99, which would put them among the worst teams in baseball. The analysis notes that “it can’t really get worse for the Rockies than it’s already been,” which is telling.

Their lineup still depends heavily on Kris Bryant, who has played fewer than 80 games in each season since signing his seven-year, $182 million deal in 2022. The analysis explicitly states the Rockies “have been among the bottom three teams in baseball for the past five years, and it’s hard to imagine they’re not close to that level again in 2025.”

Their projected rotation of Kyle Freeland, Ryan Feltner, Austin Gomber, Germán Márquez, and Antonio Senzatela doesn’t inspire confidence either, especially considering the challenges of pitching at Coors Field.

At +200, the Rockies offer better value than the White Sox while still having a strong chance of finishing with the fewest wins.

Miami Marlins (+425): Solid Dark Horse Pick

At +425, the Marlins present an intriguing option. The team analysis describes their offense as potentially “a cataclysm, a mudslide, a no-good-very-bad-day” with only the Chicago White Sox projected to have a “soggier lineup.”

Their projected record of 70-92, with just 1.8% odds of making the playoffs, indicates how low expectations are for this team. The Marlins are described as possibly finishing “with the worst record in the NL,” and their lineup appears to be in shambles after trading away key pieces at last year’s deadline.

The one bright spot is their pitching, particularly if Sandy Alcantara returns successfully from Tommy John surgery. However, this might not be enough to avoid a disastrous season, making the Marlins a solid value pick at these odds.

Longshot Value: Pittsburgh Pirates (+6600)

If you’re looking for a long shot with legitimate potential, the Pirates at +6600 offer intriguing value. While they’re projected to finish with a 78-84 record, there are several factors that could push them toward the bottom:

Their offense is described as “ill-equipped,” and there’s “not a clear path to build an above-average offense.”

Their closer, David Bednar, is coming off a season where “things went haywire” after previously being one of baseball’s best.

Despite having Paul Skenes as a potential ace, the analysis notes that if “some portion of the promising pitching staff either gets injured or regresses hard,” they could be in serious trouble.

They’ve finished in last place the past two seasons despite having similar expectations to this year.

At +6600, the Pirates represent a high-risk, high-reward option that has legitimate pathways to underperforming expectations dramatically.
