Diamondbacks catcher Andrew Knizner cleared waivers following his recent DFA and has been assigned outright to Triple-A Reno, reports Andrew Weiner of Arizona Sports. The D-backs designated Knizner for assignment over the weekend to open 40-man roster space for lefty Brandon Hughes.
While Knizner has the right to reject the assignment based on his four-plus years of major league service, he’ll likely accept it for a couple of reasons. Firstly, he’s four weeks shy of five years of big league service time, which is the threshold needed to reject an outright assignment and retain the remaining salary on a guaranteed contract. Rejecting would mean forfeiting the remainder of his $1.825MM salary this season.
Secondly, Knizner would be an option for a return to the big league roster in the event of an injury to one or more of the catchers ahead of him on the 40-man roster. There’s at least a path, albeit a narrow one, to him being brought back up during the postseason. He’d be ineligible for postseason consideration with a new team and would likely wait until the offseason to sign a new deal anyhow at this point. As a player with more than three years of MLB service who’s been outrighted off a 40-man roster, Knizner can become a free agent at season’s end if he is not added back to the 40-man roster.
Knizner, 29, was non-tendered by the Cardinals last offseason and signed a one-year deal with the Rangers. He appeared in 37 games with Texas, working as a backup to Jonah Heim and batting just .167/.183/.211 in 93 trips to the plate. That was far and away the least-productive run of his career, though Knizner entered the season as a lifetime .216/.290/.331 hitter in 794 plate appearances with the Cards, so he’s never exactly been known for his bat (at least in the major leagues). Texas designated Knizner for assignment last month, and the D-backs claimed him and optioned him to Reno. He did not appear in a big league game with Arizona but has batted .274/.357/.397 in 84 Triple-A plate appearances with the organization.
Heading into the 2024 campaign, Knizner had 4.021 years of big league service, leaving him 151 days shy of reaching five years of service. He’d have been eligible for arbitration with Texas had he spent the entire year on the roster and subsequently ticketed for free agency in the 2025-26 offseason. However, he only accrued 123 days of service in the majors this year and will thus finish out the season at 4.144 years. Because of this, whoever signs him this offseason — presumably on a minor league deal — will have the ability to control him through the 2026 season via arbitration, should he rebound at the plate and once again play his way into a steadier big league role.
