With pick No. 251 in the
2022 MLB draft, the White Sox snagged Camilletti, then a second baseman, out of Central Michigan.
A high OBP player with great plate discipline, Camilletti amassed a very impressive 207 walks over five college seasons. He was a first team All-Region and All-American selection back in 2020, carried mostly on the back of an absurd .502 OBP and a walk rate that was double that of his strikeout rate (22% vs 11%) for Central Michigan.
His small frame doesn’t project much for power, but with a god-given gift to get on base, Camilletti is an interesting prospect coming into the White Sox system. Add in some plus baserunning and manageable defense in his career, and there are more than a few things to make Camilletti and intriguing name to watch rise up through the Sox system.
Like several other draftees, Camilletti merely dipped his toe into pro play in the ACL late in 2022, getting into two games and, what new, walking twice.
He made a swift move (necessary, as he is significantly older than even A-ball competition) up to High-A during the course of 2023, following his usual pattern of selectivity at the plate and sharp but modest contact when swinging. Following a bit of a pattern established even back at college, Camilletti also saw time at third base; not much, but enough to earn additional playing time in a middle infield-heavy low minors.
Toward the end of 2023, we ran a direct piece on Camilletti via this great Q&A.
In 2024, Camilletti got off to a late start, with an injury out of the gate that pretty well killed off his April. From there, he split time between High-A and Double-A, landing in Birmingham in time to aid the Barons’ run to the Southern League title. His power game waned, but frankly it pales worse for a positive reason — Camilletti’s astronomical on-base rate.
Come 2025, things were looking more dire for Camilletti despite him seeing his first Triple-A action. Two factors stand out, most so his dwindling OBP. What was Mario’s calling card into pro ball turned pedestrian, and without a power or speed game, getting on base was crucial if he hoped for a South Side look-see. Second was, on the face of it, a positive: Camilletti moving to third base as a primary position, given that third base depth was nonexistent in 2025 for the Sox — but that wasn’t a product of his ability there, but rather a case of gotta-put-him-somewhere prioritizing other middle infielders over him. Camilletti could have turned that move into a positive, as other players have, but he’s pretty much just backed into the hot corner.
The 2026 season was more positive for Camilletti, benefiting from a full season in the pinball machine that is Charlotte’s ballpark and punching up his offensive numbers across the board (the exception being stolen base efficiency, a tool/stat that seems to matter not to the White Sox these days). There really isn’t a universe where Camilletti plays himself to the South Side, and third base is not a position of weakness any longer for the White Sox, with Miguel Vargas, Colson Montgomery, Chase Meidroth minimally able to be stationed there. But stranger things have happened.
Camilletti will ship back to Triple-A for 2027, if not occupying on-deck for a call-up, at least helping a Knights push toward the International League postseason.
