The White Sox announced that right-hander Ron Marinaccio has been designated for assignment. That’s the corresponding move for left-hander Martín Pérez, whose one-year deal has now been officially announced.
Marinaccio, 29, hasn’t appeared in a big league game for the Sox. He was claimed off waivers from the Yankees with about a week remaining in the 2024 season, but was kept on optional assignment. He has held onto his roster spot for the past four months but has now been nudged off.
The righty was generally a high-strikeout and low-control guy for the Yanks. He tossed 91 1/3 innings over the 2022 and 2023 seasons, allowing 3.05 earned runs per nine. He struck out 29% of batters faced but also gave out walks at a 13.2% clip. In 2024, he got his walk rate down to 10.1% but his strikeout rate also fell to 25.3% as he posted a 3.86 ERA.
Overall, Marinaccio has a 3.22 ERA in 114 2/3 innings, with a 28.2% strikeout rate and 12.6% walk rate. It’s generally been fairly similar in the minors. Over the past four years, Marinaccio has thrown 132 innings on the farm with a 2.86 ERA, 33.5% strikeout rate and 11.5% walk rate.
The control is clearly an issue but Marinaccio is likely to draw interest based on the strikeouts. He also still has an option remaining and barely two years of service time, meaning he still hasn’t qualified for arbitration and can be sent to the minors fairly freely for another year. The Sox will have a week of DFA limbo to figure out what’s next for the righty, though the waiver process takes 48 hours, meaning any trade talks would need to come together in the next five days.
