Mario Camilletti’s climb through the White Sox system has been a study in one skill carrying the whole profile: getting on base.
The 27-year-old third baseman checks in at No. 95 on South Side Sox’s 2027 Top Prospect list after a 2026 season at Charlotte that gave him his best statistical line yet. In 113 games, Camilletti hit 9 home runs, drove in 53, and posted a .263/.383/.387 slash line with 70 walks against 102 strikeouts. He also went 7-for-12 on stolen bases, finished with a .960 fielding percentage, and produced 2.4 WAR.
That season came at the high level, where he was 0.9 years older than the competition. Among third basemen in the system, he ranked fifth overall.
Camilletti entered the organization when the White Sox took him with pick No. 251 in the 2022 MLB draft out of Central Michigan, where he was a second baseman. His college track record was built around patience and traffic on the bases.
Over five seasons, he drew 207 walks, earned first team All-Region and All-American honors in 2020, and put together a ridiculous .502 OBP. His walk rate that year was double his strikeout rate, 22% to 11%.
The appeal was obvious even if the physical projection wasn’t. At 5´7´´ and 195 pounds, Camilletti was never going to be sold as a big power bat. But the combination of plate discipline, baserunning, and workable defense made him worth following once he entered the system.
His pro debut was tiny - just two games in the Arizona Complex League late in 2022 - and, naturally, he walked twice.
From there, he moved quickly to High-A in 2023 because he was already well beyond that level in age. The approach stayed the same: selective at the plate, modest contact when he did swing, and enough time at third base to give him another path to playing time in a system that leaned heavily on middle infielders. By the end of that year, South Side Sox had already put together a direct Q&A on him.
The 2024 season started with an injury that wiped out most of April, but he still split time between High-A and Double-A and reached Birmingham in time to help the Barons win the Southern League title. His power dipped, but the bigger story was still the same old one - a huge on-base rate doing the heavy lifting.
By 2025, the picture looked less encouraging. Camilletti got his first Triple-A run, but his OBP slipped, and that was a problem for a player without much power or speed to fall back on.
He also began spending more time at third base, but that move was more about roster necessity than a real positional breakthrough. The White Sox needed bodies at the hot corner, and Camilletti was one of the players who got pushed there.
The 2026 season brought a rebound of sorts. Charlotte’s park helped, and his offense ticked up across the board.
The one area that didn’t improve was stolen-base efficiency, which apparently doesn’t carry much weight in the White Sox universe. Still, the bigger picture remains pretty clear: there isn’t really a path where Camilletti bats or runs his way onto the South Side, and third base is no longer a glaring opening with Miguel Vargas, Colson Montgomery, and Chase Meidroth all able to be used there.
But stranger things have happened.

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 Take A Chance On Pitching Depth With Big Uncertainty
The White Sox have added another arm to the mix, signing right-hander Alec Marsh to a minor league contract with an invitation to Spring Training. It is the kind of low-risk move teams make when they are trying to build out pitching depth without tying up much in the way of resources, and Marsh brings at least some recent big-league experience after last pitching for the Royals in 2024.
Marsh also gives Chicago a familiar name for its pitching staff to evaluate up close once camp opens. The real question is how much he can offer right away as he works his way back, but the White Sox are clearly willing to take a look and see whether there is something worth uncovering before the season begins.

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 🡒]
