The Nationals have formally added a second veteran starter in free agency, announcing the addition of righty Zack Littell on a one-year deal with a mutual option for the 2027 season. Littell, a client of CAA, will reportedly be guaranteed $7MM with another $2.5MM available to him via innings-based incentives. Left-hander Richard Lovelady was designated for assignment to open roster space, per the team.

Littell’s deal reportedly pays him a $3MM salary but also includes a $4MM buyout on that mutual option. Since mutual options are never exercised, that amounts to little more than an accounting measure; the Nats are kicking $4MM of his $7MM commitment to the 2027 books rather than the 2026 books. The contract is also said to contain $100K bonuses for every tenth inning pitched from 100 through 140. Littell can earn $250K for reaching each of 150 and 160 innings, and the deal has $500K bonuses upon reaching 170, 180 and 190 innings.

Heading into the offseason, we ranked Littell 35th among the offseason’s top 50 free agents, predicting a two-year deal. He’ll have to settle for just a one-year pact, and the righty could be on the move again relatively soon if the rebuilding Nationals move him at the trade deadline.

The 30-year-old Littell is a veteran of eight big league seasons but spent most of that time in a bullpen role. In the first five seasons of his MLB career, Littell posted a 4.08 ERA (104 ERA+) with lackluster peripherals in 169 2/3 innings of work. After the 2022 campaign, Littell rode the DFA and waiver carousel throughout the 2022-23 offseason. He eventually wound up with the Red Sox to start the season, but he made just two appearances in the majors before being once again designated for assignment. That led him to the Rays, with whom he managed to transform himself from a fringe member of the 40-man roster into a solid rotation arm.

Upon arriving in Tampa, Littell moved into a swing role for the remainder of the 2023 campaign. He posted a 3.93 ERA with a nearly matching 3.99 FIP in 87 innings split between 14 starts and 12 relief appearances. Littell’s 19.8% strikeout rate in those outings was hardly exciting, but he made up for it with pinpoint command that allowed him to post a 2.5% walk rate and an 8.2% barrel rate.

That control and command style was enough to earn him a full-time rotation job headed into the Rays’ 2024 season, and he rewarded the team with a career year. In 29 starts for the Rays in 2024, Littell posted a 21.5% strikeout rate against a 4.7% walk rate while pitching to a 3.63 ERA (110 ERA+) with a 3.81 FIP. His 156 2/3 innings of work made him just one of just 71 pitchers to throw more than 150 innings that year, and only 15 of those pitchers surrendered fewer runs than Littell.

Littell remained generally effective in terms of run prevention last year, logging a 3.81 ERA (111 ERA+) in a career-high 186 2/3 innings across 32 starts for the Rays and Reds. The bottom-line results were similar, but Littell’s rate stats took worrying steps in the wrong direction. His strikeout rate plummeted to just 17.1%, while his barrel rate jumped to 9.8% as he allowed the second-most homers in all of baseball last season. Perhaps some of that can be explained by Littell pitching his home games at the hitter-friendly Steinbrenner Field and Great American Ballpark, but a 4.40 SIERA suggested that Littell was more of a back-end starter than his results may have indicated.

The result was a soft free agent market for Littell this offseason. A reunion with the Rays once seemed to be on the table, but Tampa Bay instead brought in Steven Matz and Nick Martinez. KSTP’s Darren Wolfson reports that the Twins at least checked in late in the offseason, but weren’t inclined to match the Nationals’ offer.

The Nationals were the ones to ultimately bring Littell into the fold, with some past connections possibly helped complete the deal.  New president of baseball operations Paul Toboni formerly worked in the Red Sox front office, new manager Blake Butera spent years managing in Tampa’s farm system, and new pitching coach Simon Matthews was the Reds’ assistant pitching coach in 2025, so all three have direct familiarity with Littell’s work.

D.C. is unlikely to compete for a playoff spot this year as they reboot their rebuilding efforts under Toboni. As such, the team has pursued just short-term and relatively inexpensive veteran signings like Littell and Miles Mikolas, and made another move for the future in trading MacKenzie Gore to the Rangers. The Gore trade diminished an already questionable Washington rotation, so Littell will reinforce a starting five that seems set to include Mikolas and another new signing in Foster Griffin. The last two spots in the rotation figure to go to some combination of Cade Cavalli, Brad Lord, Josiah Gray, Jake Irvin, and Mitchell Parker.

ESPN.com’s Kiley McDaniel and Jeff Passan were the first to report the agreement between the two sides. The Baltimore Banner’s Andy Kostka (multiple links) had the details about the one-year term and mutual option. The Banner’s Andrew Golden first reported the financial guarantee. Jon Heyman of The New York Post and Spencer Nusbaum of The Athletic added specifics about the breakdown and incentives.
