The Nationals have signed right-hander Zack Littell to a one-year, Major League contract that includes a mutual option for the 2027 season. Financial teams of the contract aren’t yet known. The deal will become official when Littell passes a physical, and when Washington makes a corresponding move for the CAA Sports client to create space on the 40-man roster.
Littell ranked 35th on MLB Trade Rumors’ list of the offseason’s top 50 free agents, and was predicted to earn a two-year, $24MM 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.
Littell, 30, 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 claim 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 mid to back of the 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 as he posted a 3.81 ERA (111 ERA+) in a career-high 186 2/3 innings of work across 32 starts for the Rays and Reds. Unfortunately, those solid results were not paired with similar peripherals. A look under the hood reveals Littell’s 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 4.88 FIP with 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, with minimal interest in his services being reported. A reunion with the Rays once seemed to be on the table, but Tampa Bay instead brought in Steven Matz and Nick Martinez. No other clubs were publicly connected to the right-hander’s services for most of the winter, though plenty of pitching-needy teams like the Braves and Athletics emerged as speculative fits.
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, with Joel Sherman of the New York Post reporting that Littell had signed a guaranteed contract. The Baltimore Banner’s Andy Kostka (multiple links) had the details about the one-year term and mutual option, and Littell needing to pass a physical.
