The Blue Jays and right-hander Adam Kloffenstein have agreed to a minor league deal, reports Ari Alexander of KPRC 2. The righty will also be in big league camp with the Jays as a non-roster invitee.
Kloffenstein, 24, returns to his original club. The Jays selected him in the third round of the 2018 draft. For the next few years, he was a somewhat notable prospect in Toronto’s system. Baseball America ranked him in the middle parts of the Blue Jays’ top 30 from 2019 to 2022. At the 2023 deadline, the Jays flipped him to the Cardinals as part of the Jordan Hicks trade.
The Cards added Kloffenstein to their 40-man roster last offseason to keep him out of the Rule 5 draft. That allowed him to make his major league debut in 2024, though he tossed only one inning. His Triple-A numbers weren’t amazing on the year, as he allowed 4.74 earned runs per nine innings over his 17 starts. His 49% ground ball rate was strong but his 19.4% strikeout rate and 10.9% walk rate were both subpar.
After that uninspiring year, the Cards decided to move on. Kloffenstein was non-tendered in November, getting sent to free agency without being put on waivers. That allowed him to return to the Jays on this minor league pact.
From 2021 to 2023, Kloffenstein tossed 341 1/3 minor league innings, most of that with the Blue Jays. The results in that time were a bit better than in his 2024 season. His 4.85 ERA still wasn’t especially impressive but his 24% strikeout rate was significantly better than last year’s clip, with comparable amounts of walks and ground balls.
The Jays are plenty familiar with Kloffenstein from his time in the system, so perhaps they believe there’s a way to get him back on track after a challenging season. The Jays have Kevin Gausman, Chris Bassitt and José Berríos locked into three rotation spots. Bowden Francis will probably get a chance to build off his strong finish in 2024. Guys like Yariel Rodríguez, Jake Bloss and Adam Macko are candidates for another spot. The Jays have been looking to upgrade that group this offseason and could push everyone down a peg but Kloffenstein gives them some non-roster depth alongside Eric Lauer. If Kloffenstein eventually gets a roster spot, he still has options and just a single day of service time.
