Former Guardians right-hander files for free agency

Right-hander Zach Plesac recently filed for free agency, according to his player profile on MLB.com. Plesac, 28, struggled to a 7.59 ERA and 4.47 FIP across five starts with the Guardians this season before being designated for assignment back in June. His struggles continued at the Triple-A level after he accepted an outright assignment, with the righty posting a 6.08 ERA in 19 appearances for the club’s affiliate in Columbus.

Plesac made his major league debut in 2019 and had the look of a solid mid-rotation starter, with a 3.81 ERA (126 ERA+) across 21 starts in his rookie season, though his 4.94 FIP and lackluster 18.4% strikeout rate both left much to be desired. During the shortened 2020 season, Plesac took a significant leap forward, with an incredible 2.28 ERA that was 96% better than league average by measure of ERA+ and a strong 3.39 FIP. In the shortened season, Plesac’s peripherals caught up to his performance as he struck out 27.7% of batters faced while walking just 2.9%.

Headed into the 2021 campaign, Plesac looked like he’d be a stalwart of Cleveland’s rotation for years to come. That did not come to pass, however, as Plesac reverted to his previous, low-strikeout rate form in 2021 and beyond. Unlike 2019, however, his results fell back down to Earth alongside his peripherals, leaving him with a 4.49 ERA (90 ERA+) and a 4.59 FIP across 274 1/3 innings between 2021 and 2022. During that time, he struck out a measly 17.2% of batters faced, the fifth-worst punchout rate among starters with at least 250 innings pitched between the two seasons.

Now that Plesac has elected free agency, he’ll be able to look for the chance to continue his career with any of the 30 big league clubs. Given his brutal results both in the majors and at Triple-A this year, it’s hard to imagine him finding anything better than a minor league offer with a contender. That said, it’s at least feasible that a team without hope of contending next season could offer Plesac a spot in the Opening Day rotation given the upside he flashed early in his career, his relative youth, and the fact that he could be controlled beyond the 2024 campaign.

If such an offer doesn’t materialize, Plesac could be one of the more interesting depth starters to be had on a minors pact this winter. After all, even his considerably diminished performance in 2021 and 2022 was just below league average for a starting pitcher, and even a contending club could do far worse than Plesac if looking for a stopgap option to cover for a midseason rotation injury. Further adding to his value on the open market is the fact that Plesac has minor league options remaining, meaning an interested club could shuttle him from the majors to Triple-A throughout next season without exposing him to waivers.
