Nationals Secure Zack Littell on One-Year Deal with 2027 Mutual Option

Right-hander Zack Littell joins the Washington Nationals rotation following a 2025 season defined by 186.2 innings pitched and a 3.81 ERA.

Zack Littell signed a one-year Zack Littell contract with the Washington Nationals on Sunday, a deal that includes a mutual option for the 2027 season. The 30-year-old right-handed pitcher arrives in the District of Columbia following a 2025 campaign where he produced a 10-8 record and a 3.81 ERA. This agreement, confirmed by ESPN’s Jeff Passan and Kiley McDaniel, adds a durable arm to a rotation seeking stability after the veteran logged 32 starts last year.

During his 2025 tenure, Littell established a new career high by throwing 186.2 innings. A primary highlight of his season occurred on May 31, when he tossed his first career complete game while playing for the Tampa Bay Rays. In that specific outing, he dominated the Houston Astros in a 16-3 road victory, showcasing the efficiency that the Nationals hope to replicate in the National League East. His ability to maintain a sub-4.00 ERA over such a significant workload made him a primary target in the free-agent market this winter.

The pitcher’s journey to Washington follows a midseason trade on July 30, 2025, which sent him from the Tampa Bay Rays to the Cincinnati Reds. This transition forced the right-hander to adjust to National League hitters during the heat of a pennant race. Despite the change in scenery, he remained a consistent presence on the mound, finishing the year with double-digit wins for the first time in his professional career. The Nationals are banking on this recent trajectory of high-volume performance to anchor their starting five.

Statistically, Littell’s 2025 metrics were bolstered by his command and the ability to pitch deep into games. By reaching the 32-start threshold, he proved his physical durability, a trait that the Washington front office prioritized during negotiations. The mutual option for 2027 provides a layer of security for both the organization and the athlete, allowing for a potential extension of the partnership if the initial season proves successful. This structure reflects a strategic move to stabilize the pitching staff with a proven veteran who has experience in both the American and National Leagues.

Reporting from the Associated Press noted that the deal was finalized as the club looks to improve upon its previous standings. Littell’s arrival marks a shift toward acquiring players with recent histories of heavy workloads and reliable health. As the 2026 season approaches, the right-hander is expected to occupy a prominent slot in the rotation, bringing his 3.81 ERA to a ballpark known for being neutral to pitchers. The specifics of the financial terms were not immediately disclosed, but the commitment to a mutual option suggests a shared interest in a long-term fit within the organization’s rebuilding timeline.
