White Sox Claim Ron Marinaccio

Right-hander Ron Marinaccio, who was designated for assignment by the Yankees last week, has been claimed off waivers by the White Sox. Both clubs announced the move, with the Sox adding that Marinaccio has been assigned to Double-A Birmingham. The Double-A regular season is done but the Barons are playing in the Southern League championship this week, whereas the Triple-A Charlotte Knights are done for the year. The Sox had a 40-man roster vacancy after righty Chad Kuhl was designated for assignment recently and won’t need to make a corresponding move in that regard.

Marinaccio got nudged out of the Yankees’ plans but it’s unsurprising that he got picked up by the club with the top waiver priority. Now 29, he made his major league debut in 2022 and it was strong first impression. He logged 44 innings for the Yanks that season, only allowing 2.05 earned runs per nine. His 13.3% walk rate was definitely worrisome but he managed to work around that by striking out 30.9% of batters faced.

His results backed up a little bit from there. He had a 3.99 ERA in 47 1/3 innings last year. He still walked too many guys, a rate of 13.2%, with his strikeout rate slipping slightly to 27.3%. Here in 2024, the Yanks have frequently shuttled him back and forth between the majors and Triple-A. His 23 1/3 big league innings resulted in a 3.86 ERA with a reduced 10.1% walk rate but also a diminished 25.3% strikeout rate. At the Triple-A level, he has 39 2/3 innings with a 2.04 ERA, 25.8% strikeout rate and 8.8% walk rate.

Those are pretty decent numbers overall but he was getting squeezed from the roster in the Bronx. He had already been optioned five times this season, the maximum amount in an individual campaign. He’s also in his final option season and will be out of options next year.

It was therefore going to be challenging for him to continue hanging onto his roster spot on a competitive Yankee club going forward, so he got pushed out last week when Cody Poteet was ending his rehab assignment and needed to get added back to the 40-man.

But for the White Sox, he’s a sensible flier to take. As the worst club of the modern era, the Sox have plenty of room for guys who have shown promise elsewhere. Marinaccio has just over two years of service time and still won’t have qualified for arbitration this winter. He can be controlled for four seasons beyond the current campaign. If things click in Chicago next year, he can be a long-term part of their bullpen or perhaps become a valuable trade chip.
