Introduction

As the 2025 Major League Baseball season approaches its end, expectations have been dramatically shattered across the league. While several players and teams were positioned for breakout performances, many have instead fallen well short of the mark. In this article, we delve into the ten most disappointing players and teams of the season.

Major Disappointments

Heading into the season, Dylan Cease and Zac Gallen were touted as premier candidates for the NL Cy Young, particularly with free agency on the horizon. However, their performances have left much to be desired. The Dodgers' bullpen was anticipated to be an unstoppable force, while the Yankees were banking on Devin Williams to become a game-changing closer. Yet, both scenarios have turned out drastically different than expected.

Honorable Mentions

The following players have also seen their stock plummet this season:

• Sandy Alcantara, Miami Marlins: Once a top contender, Alcantara has a 3.16 ERA over his last six starts but struggles could see him drop from elite status.
• Jac Caglianone, Kansas City Royals: Caglianone's transition to the majors hasn’t gone as planned, posting a mere .485 OPS.
• Jordan Hicks, San Francisco Giants/Boston Red Sox: Acquired in a trade, Hicks has underperformed significantly with a 6.47 ERA for the Giants and 6.60 for the Red Sox.
• Shane McClanahan, Tampa Bay Rays: After recovering from Tommy John surgery, McClanahan has faced further setbacks, undergoing another season-ending operation.
• Aaron Nola, Philadelphia Phillies: Despite a solid track record, Nola’s 6.92 ERA and injury struggles have cast a shadow on his season.
• Yordan Alvarez and Christian Walker, Houston Astros: Both sluggers are currently in negative bWAR territory, raising questions about their ability to reclaim former glory.

Team Disappointments

The Baltimore Orioles faced monumental expectations with pre-season World Series odds, yet found themselves at a staggering 10 games below .500 early in the season. Conversely, the New York Mets experienced a drastic turnaround last year but find themselves burdened by disappointing performers like Mark Vientos, who has seen his value plummet this season.

The Pittsburgh Pirates, without high expectations, are still failing to meet even minimal offensive thresholds, ranking last in home runs and runs scored. Meanwhile, confidence in the Texas Rangers has been shaken as they also grapple with disappointing production, particularly from high-profile signings like Joc Pederson.

Conclusion

While these disappointments are a part of the game, they can significantly impact franchises and players alike. As we continue to follow the conclusion of the 2025 MLB season, eyes will be on these key underperformers to see if they can turn it around before the postseason begins.
