Introduction

As the MLB award season approaches, focus often shifts to the stellar performances of top pitchers. However, not every pitcher enjoys a successful season. In 2025, several pitchers struggled mightily, with some turning in truly dismal campaigns. In this article, we dive into the statistics of the worst pitchers of the 2025 season.

Notable Disappointments

This season's worst pitchers include both starters and relievers who had exceptionally rough outings, leaving their teams in tough positions. Only pitchers who logged at least 100 innings or 40 innings for relievers are considered.

Top of the List

Chivilli (2025 Stats: 7.06 ERA, 6.03 FIP, minus-0.7 WAR, 43 games, 58.2 IP) ranked among the lowest, demonstrating how poor performance can contribute to a team's back-to-back 119-loss season. Despite pitching at Coors Field—renowned for its hitting-friendly nature—Chivilli struggled significantly even in away games, and at just 23 years old, the Rockies might bring him back for another chance in 2026.

Rolison (2025 Stats: 7.19 ERA, 6.89 FIP, minus-0.7 WAR, 30 games, 42.1 IP) is another young pitcher whose numbers left fans wanting more. Over 42.1 innings, he surrendered 55 hits and walked 20 batters, leading to disappointing performances both at home and on the road. Being a first-round pick in 2018, he still has potential but has yet to live up to expectations.

Struggles Continue

Cabrera (2025 Stats: 6.54 ERA, 6.56 FIP, minus-0.9 WAR, 40 games, 42.2 IP) faced similar challenges, having pitched for four different teams in one season. While he had some effective outings earlier in his career, the 2025 season was a significant downturn. A minor league deal might be in Cabrera's future as he seeks to find stability in his career.

Senzatela (2025 Stats: 3-16, 6.70 ERA, 5.47 FIP, 0.3 WAR, 126.1 IP), also representing the Rockies, found himself among the bottom-tier pitchers this season, allowing an astounding 192 hits and suffering 15 losses. With a challenging season behind him, Colorado must strategize how to utilize him moving forward.

Looking Ahead

Márquez (2025 Stats: 3-11, 6.81 ERA, 6.05 FIP, minus-0.6 WAR, 111 IP) was once a promising All-Star but has seen a decline in performance since returning from Tommy John surgery. As he approaches free agency, his future in MLB could hinge on proving he's still capable of being effective.

Kochanowicz (2025 Stats: 6.81 ERA, 6.05 FIP, minus-0.6 WAR, 130 IP) had a year to forget, finishing dead last among starters. The 24-year-old will need to reflect on this season's challenges to secure his role moving forward.

Romano (2025 Stats: 8.23 ERA) faced perhaps the steepest decline, suffering substantial embarrassment as the Phillies avoided showcasing him during the playoffs. His nightmare season included an inside-the-park home run and a potential end to his time with Philadelphia due to ongoing injuries.

Conclusion

While some pitchers shine, others struggle in the competitive environment of Major League Baseball. The 2025 season showcased a handful of players who now have their work cut out for them if they wish to bounce back in upcoming seasons.
