The White Sox are dipping into the bargain bin early this offseason, and their latest move comes with a little upside if the health cooperates.
Chicago has signed right-hander Alec Marsh to a minor league deal with an invite to Spring Training, according to MLB.com’s Scott Merkin. Marsh, 28, hasn’t pitched for the Royals since 2024 and has been out because of shoulder problems. He is still rehabbing from labrum surgery in October 2025, so his availability for Spring Training 2027 remains very much up in the air.
Marsh entered pro ball as a second-round pick in the 2019 MLB Draft and climbed high enough in Kansas City’s system to reach No. 12 on MLB Pipeline’s prospect rankings in 2021. The appeal was obvious: a four-pitch mix built around a mid-90s fastball that could touch triple digits. But even as the stuff drew attention, hard contact and command issues kept following him up the ladder.
His big-league debut came on June 30, 2023, against the Dodgers, and it was a rough first look. Marsh allowed five runs on six hits in a little more than four innings in a 9-3 Royals loss.
He finished that rookie year 3-9 with a 5.69 ERA in 17 appearances, including eight starts. There were still flashes, though, including an 11-strikeout outing in just his third major league appearance against the Twins.
He took a step forward in 2024 and opened the season in Kansas City’s rotation. Over 26 appearances, 25 of them starts, Marsh went 9-9 with a 4.53 ERA and 123 strikeouts in 129 innings. The improvement was real, but consistency was still missing, and the Royals optioned him to Triple-A Omaha after the trade deadline before bringing him back to the majors in September.
Across his first two seasons, Marsh posted a 12-18 record with a 4.96 ERA, 208 strikeouts and 78 walks in 203.1 innings.
For the White Sox, this is the kind of low-cost move that can quietly matter if the arm bounces back. Marsh also has a built-in connection in Chicago, since pitching coach Zach Bove was on the Royals’ staff when Marsh first reached the majors. If the recovery goes well, the White Sox could end up with some extra rotation or bullpen depth.

White Sox Young Core Just Earned Another Chance To Prove It
The White Sox got another reminder that their young core is starting to draw real leaguewide notice, with four players landing among the American League finalists for the Louisville Slugger Silver Slugger Awards. Chase Meidroth, Miguel Vargas, Tristan Peters and Sam Antonacci all earned nominations at their respective spots, a nice snapshot of how much of Chicagos 2026 offense was driven by emerging talent rather than established names.
For a club still trying to turn promise into something more durable, the groups presence on the finalist list matters as much for what it says about the season as for the hardware itself. Meidroth, Vargas, Peters and Antonacci all put together enough production to get into the conversation at second base, third base, in the outfield and as a utility option, and now they get one more chance to turn strong years into an award when the winners are revealed on November 17.

White Sox Prospects Are Forcing A Bigger Timeline Question
The White Sox keep finding reasons to look a little farther down the road, and the Arizona Fall League is giving them more of them. Caleb Bonemar, the organizations No. 2 prospect, has put together strong offensive numbers this fall, while right-hander Jonathan Clark has been effective out of the bullpen, adding to a growing list of Chicago prospects who have earned notice in the showcase circuit.
For a club still sorting out its long-term picture, those kinds of honors matter because they hint at depth beyond the current roster. Bonemars bat has already made him one of the systems more closely watched names, and Clarks work in relief has only strengthened the sense that the White Sox have some legitimate pitching talent on the way. The bigger question now is how soon that next wave can start to influence the major-league conversation. [Read more 🡒]
White Sox Prospect Faces A Tough Path Despite One Valuable Skill
Mario Camilletti has kept himself on the White Sox radar the same way he did in college at Central Michigan, by controlling the strike zone and getting on base. Since being drafted in 2022, the third base prospect has climbed through High-A, Double-A and Triple-A while showing the kind of plate discipline that can make a player useful even when the bat is not carrying him every night.
The problem is that the path from useful prospect to big league opportunity is not always straight, and Camilletti has run into the usual detours along the way, including injury and some erosion in his on-base production. He has continued to develop at third base, but with the White Sox already stocked there, his best skill may not be enough to clear a clean lane to Chicago anytime soon. [Read more 🡒]
