The Orioles announced this afternoon that left-hander has cleared waivers and been a signed outright to Triple-A. The 29-year-old was earlier this week amid a flurry of roster moves that saw recently-acquired southpaw optioned to the minor leagues. Zimmermann was selected by Tony Bradley Jersey the Braves in the fifth round of the 2017 draft but was traded to the Orioles during the summer of 2018 as part of the package that brought and to Atlanta. The lefty reached the Triple-A level the following year after dominating to the tune of a 2.58 ERA in 101 1/3 innings of work at Double-A earlier in the year, and that stint at the highest level of the minors teed him up for his big league debut with Baltimore during the pandemic-shortened 2020 season. That debut didnt go quite as well as Zimmermann and the Orioles were surely hoping for, however, as he struggled badly with a 7.71 ERA in his seven-inning cup of coffee that year. The lefty enjoyed a larger role with the Orioles over the next two seasons as he stepped into a rotation role with the club, though he was limited to about half of a full seasons workload in both years by injuries and occasional trips to Triple-A. Zimmermanns results were about what youd expect from a part-time starter for a club in the midst of a lengthy rebuild, as he struggled to a 5.54 ERA that was 25% worse than league average with a 5.74 FIP acro s a combined 138 innings of work in those years. Zimmermann was removed from the rotation entering the 2023 campaign and spent most of the campaign at the Triple-A level, although he did make a brief appearance in the big leagues as a multi-inning reliever that summer. He performed pa sably in the new role, with a below-average 4.73 ERA in his 13 1/3 innings of work but a solid 23% strikeout rate that stood as a considerable step up from his lackluster 17.4% strikeout rate during his time as a starter. The lefty has not yet appeared in the big leagues in 2024 after undergoing core muscle surgery last October, although he has made it back to the minor leagues where hes pitched to a middling 4.64 ERA in 66 innings of work at the Triple-A level with a somewhat concerning 8.5% walk rate thats quite a bit higher than the 5.2% clip hes posted in the big leagues to this point in his career. Now that Zimmermann is off the 40-man roster, he figures to remain with with Orioles as non-roster depth through the end of the season, at which point hell have the opportunity to elect free agency if he hasnt been added back to the 40-man by then. The lefty is currently in his final option year, meaning that Baltimore would have the opportunity to shuttle him between Triple-A and the majors as needed down the stretch if they were to add him back to the roster at some point.
