Zack Littell, 30, was placed on release waivers by the Diamondbacks after being designated for assignment earlier in the week. Littell had joined Arizona earlier in the month following a previous stint with the Washington Nationals. In his time with the Diamondbacks, he worked 12 innings and surrendered 10 earned runs, allowing 21 hits while recording three strikeouts.
Context on Littell’s MLB journey shows a nine-year career during which he has appeared in 211 games, including 93 starts. His overall numbers include a 4.11 ERA across 727 innings, with 569 strikeouts. In 2026, Littell appeared in 26 games (14 starts), posting a 5.21 ERA and compiling 124.1 innings pitched with 73 strikeouts and a WHIP of 1.408. While he had been a reliable starter from 2023 through 2025, his effectiveness declined in the current season, notably in his strikeout rate.
Following his designation for assignment, Littell became a free agent eligible to sign with any MLB club. The long-term question for him involves whether another team will carry him on its big-league roster or if he will pursue opportunities in the minor leagues as rosters adjust in September.
Looking ahead, Littell’s career arc could lead him to a new opportunity with another organization, should he be picked up as rosters expand or if a team seeks depth in its pitching staff. His veteran experience and prior major-league track record might appeal to clubs seeking pitching depth on a short-term or organizational level.
Key stats to know about Littell:
– MLB appearances: 211 (93 starts)
– Career ERA: 4.11
– career innings: 727
– Strikeouts: 569
Teams Littell has been associated with include several MLB clubs over a nine-year span, reflecting a journeyman profile that could still find a fit with a club in need of pitching depth as the season progresses.
As the league moves toward September rosters, it will be interesting to see if Littell signs with another club and how he fits into a bullpen or starting rotation role, depending on the needs of the team and the prorated salary terms available to a new signing.
