Standing out for his durability and adaptability, Littell has transitioned between bullpen and rotation roles throughout his career. Through the early portion of the 2026 season, his cumulative major league line stands at a 40-35 win-loss record, a 4.05 earned run average (ERA), and 537 strikeouts.

Early Life and Background
Zachary Stuart Littell was born on October 5, 1995, in Mebane, North Carolina. He grew up in the Piedmont region of the state and attended Eastern Alamance High School in his hometown. As a young athlete in a region with a deep baseball tradition, Littell developed his pitching mechanics in local amateur circuits before catching the attention of professional scouts.
Coming out of high school, Littell had committed to play college baseball at Appalachian State University, but that path changed when the Seattle Mariners selected him in the 11th round of the 2013 MLB draft. He signed with Seattle and chose to begin his professional career immediately, forgoing his collegiate opportunity to pursue the long road through the minor leagues.
Path to Baseball
Littell made his professional debut in 2013 with the Rookie-level Arizona League Mariners, working through the inevitable growing pains of a first-year pitcher. He went 0-6 with a 5.94 ERA in 33 and one-third innings that summer, an early indication of the adjustments required at the professional level. The following year, he advanced to the Advanced Rookie League Pulaski Mariners and posted a 5-5 record with a 4.52 ERA in 13 starts, showing incremental progress.
In 2015, Littell spent the season with the Single-A Clinton LumberKings, where he recorded a 3-6 mark and a 3.91 ERA across 21 starts. His breakout minor league campaign came in 2016, when he split time between Clinton and the Bakersfield Blaze, combining for a 13-6 record and a 2.66 ERA in 28 total appearances. That performance placed him firmly on the radar of organizations seeking young arms for their upper-level systems.
Zack Littell Career
Early Career (2013-2017)
After his strong 2016 showing in the Seattle system, the Mariners traded Littell to the New York Yankees on November 18, 2016, in exchange for pitcher James Pazos. He began 2017 with the Tampa Yankees before earning a promotion to the Double-A Trenton Thunder in late June. His development continued rapidly, and on July 30, 2017, the Yankees dealt him and pitcher Dietrich Enns to the Minnesota Twins for Jaime García and cash considerations, with the Twins assigning him to the Chattanooga Lookouts.
Across all three minor league stops in 2017, Littell compiled a 19-1 record with a 2.12 ERA, a mark that demonstrated both consistency and the ability to handle a workload. The Twins recognized his progress by adding him to their 40-man roster on November 20, 2017, to protect him from the upcoming Rule 5 draft, signaling that his major league debut was close at hand.
Minnesota Twins Era (2018-2020)
Littell made his MLB debut on June 5, 2018, fulfilling years of minor league preparation. In eight appearances for the Twins that season, he went 0-2 with a 6.20 ERA across 20 and one-third innings, learning on the job against major league hitters. He split the rest of the year between the majors and the minors, where he posted a 6-9 record with a 3.98 ERA.
The 2019 season saw Littell move to the bullpen full time, a transition that suited his arsenal. He went 6-0 with a 2.68 ERA, 32 strikeouts, and only nine walks in 29 games covering 37 innings, marking his most effective major league stretch to that point. In 2020, however, he struggled in limited opportunities, allowing five home runs and posting a 9.95 ERA in just six and one-third innings. The Twins outrighted him off the 40-man roster on September 17, 2020, and he elected free agency on November 2.
San Francisco Giants Era (2021-2022)
Littell signed a minor league deal with the San Francisco Giants on February 3, 2021, and received an invitation to spring training. The Giants promoted him to the major leagues on April 30, and he rewarded that decision by going 4-0 with a 2.92 ERA in 63 appearances covering 62 and two-thirds innings, striking out 63 batters. His 2021 season re-established him as a reliable relief option in a contending bullpen.
The 2022 season was more turbulent. On September 13, 2022, after yielding two earned runs on three hits and a walk on only 15 pitches, Littell was removed by manager Gabe Kapler, an encounter that included a heated exchange when Littell slammed the ball into Kapler’s hand. The following day, the Giants demoted him to the Triple-A Sacramento River Cats, and he finished the year 3-3 with a 5.08 ERA in the majors. The Giants outrighted him in November 2022, and he elected free agency once again.
Boston Red Sox and Tampa Bay Rays Eras (2023-2025)
After a brief stint with the Texas Rangers organization in early 2023, Littell was traded to the Boston Red Sox on May 5, 2023, only to be designated for assignment five days later after surrendering three runs in three innings. The Tampa Bay Rays claimed him off waivers on May 12, 2023, and the organization converted him back into a starting pitcher. On August 4, 2023, he delivered a career-high six scoreless innings to earn a win against the Detroit Tigers, finishing the year 3-6 with a 4.10 ERA across multiple clubs.
His most consistent major league work came with the Rays in 2024, when he made 29 starts and posted an 8-10 record with a 3.63 ERA and 141 strikeouts, leading the team in innings pitched. On May 31, 2025, he threw a complete game against the Houston Astros, scattering 10 hits and three earned runs over 117 pitches. He made 22 starts for Tampa Bay in 2025, going 8-8 with a 3.58 ERA and 89 strikeouts across 133 and one-third innings.
Cincinnati Reds Era (2025)
On July 30, 2025, the Rays traded Littell to the Cincinnati Reds in exchange for Brian Van Belle and Adam Serwinowski, shifting him to a National League contender. In his short stint with Cincinnati, he made 10 starts and compiled a 2-0 record with a 4.39 ERA and 41 strikeouts across 53 and one-third innings, offering steady innings for a rotation that needed length.
Washington Nationals Era (2026-Present)
On March 10, 2026, Littell signed a one-year, $7 million contract with the Washington Nationals, a deal that included performance incentives and a mutual option for the 2027 season. He joined a young Washington club looking to add veteran stability to its pitching staff, and through the early portion of the 2026 schedule, his cumulative MLB line included a 40-35 record, a 4.05 ERA, and 537 strikeouts. The contract reflected both his durability as a starter and his track record of eating innings in competitive lineups.
Driving Style and Strengths
Littell has built his career on command, durability, and the ability to adapt between roles, succeeding as a multi-inning reliever before transitioning into a back-of-the-rotation starter. His consistency in throwing strikes and logging innings made him a reliable innings-eater for the Rays in 2024 and 2025, while his bullpen background gives managers a quick path to call on him in leverage spots when needed.
Notable Events and Milestones
Among his signature moments, Littell recorded a career-high six scoreless innings against the Detroit Tigers on August 4, 2023, and later threw a complete game against the Houston Astros on May 31, 2025. His heated exchange with Giants manager Gabe Kapler on September 13, 2022, remains one of the most discussed episodes of his career and led directly to his demotion to Triple-A Sacramento the following day.

2025 Season Performance
The 2025 season split into two distinct chapters for Littell, beginning with a strong first half in Tampa Bay. He made 22 starts for the Rays, going 8-8 with a 3.58 ERA and 89 strikeouts across 133 and one-third innings, anchoring the rotation while logging a complete game against the Houston Astros on May 31, 2025.

Looking beyond 2025, Littell’s market value was reinforced when the Washington Nationals signed him to a one-year, $7 million contract on March 10, 2026, with performance incentives and a mutual option for 2027. The deal signaled confidence in his durability and his ability to handle a starter’s workload, setting the stage for a continued major league role into 2026 and potentially beyond.
