The Tigers announced a pair of roster moves this morning. They’ve selected the contract of left-hander PJ Poulin to the 40-man roster and optioned him to Triple-A Toledo. Left-hander Sean Guenther was recalled from Triple-A and placed on the 60-day injured list to make room for Poulin on the 40-man roster. According to Evan Woodbery of MLive, Poulin had an upward mobility clause in his contract and the Tigers opted to add him to their 40-man roster in order to keep him in their organization.
Poulin, 29 later this month, was an 11th-round pick by the Rockies back in 2018. A two-way player in college, Poulin committed to pitching upon his move to affiliated ball. He looked quite good in the lower minors as a reliever in his first two years as a professional, but the canceled minor league season in 2020 lost him a year of development and he generally struggled with his effectiveness in the upper minors during his time with the Rockies organization.
He was dealt to the Tigers prior to the 2024 season and has looked quite good since then, as he posted a 2.10 ERA in 60 innings between Double- and Triple-A last year before posting a 3.72 ERA in 36 1/3 frames at Triple-A this season. That solid but unspectacular ERA comes with a much more impressive 33.8% strikeout rate, and that kind of strikeout stuff from the left side makes it easy to see why the Tigers decided it was worth it to add the lefty to their 40-man roster rather than risk losing him to another organization.
Making room for Poulin on the 40-man roster is Guenther, who has a 2.30 ERA and 2.73 FIP across 31 1/3 innings of work with the Tigers over the past two seasons. Guenther was on the shelf in the minors after undergoing hip surgery last week, meaning that the move to place him on the 60-day IL is largely a procedural one. With that being said, it does come with the side effect of allowing him to collect a big league salary and earn MLB service time until he’s activated and optioned back to the minor leagues.
