The White Sox will call up at least one of their top prospects for Tuesday’s series opener against the Rays. Noah Schultz will start the game against Shane McClanahan in a promotion that will officially be announced tomorrow morning.
Does Chicago have another promotion looming for a highly-regarded young player? Ken Rosenthal of The Athletic and Mitchell Armentrout of The Chicago Sun-Times each write that the Sox front office is weighing whether to promote utility player Sam Antonacci. Noah Phelan of Southside Showdown reported on Saturday that Antonacci would be promoted alongside Schultz for the opener with Tampa Bay. The reports from The Athletic and Sun-Times suggest that the team has not made a final decision but that a promotion might be imminent.
It’s probably not a coincidence that the Sox traded infielder Lenyn Sosa to the Blue Jays this afternoon. Sosa led the team with 22 home runs a season ago, yet his defensive shortcomings and .293 on-base percentage made him a limited player. Chase Meidroth and Munetaka Murakami are playing almost every day on the right side of the infield. Sosa is out of options and had been in a bench role without much multi-positional versatility.
The Sox need to bring up a position player to replace Sosa on the active roster (while also dropping a pitcher from the 26-man to accommodate the Schultz promotion). Sosa’s 40-man roster spot will go to the 6’10” southpaw. Calling up Antonacci would require a second 40-man move. Drew Thorpe and Prelander Berroa each underwent Tommy John surgery early in 2025 and are candidates to move to the 60-day injured list.
The 23-year-old Antonacci is out to a quick start to the season with Triple-A Charlotte. He has reached base 30 times in 13 games, tallying 13 hits while drawing 15 walks and getting plunked twice. Antonacci’s polished plate discipline and hit tool have been his calling card as a prospect. The left-handed batter posted a .291/.433/.409 line while stealing 48 bases between High-A and Double-A last year.
Antonacci, whom Baseball America ranked the #9 prospect in the Sox’s system over the winter, has played mostly second or third base over his minor league career. That hasn’t been the case in 2026. He has started two games at second and 10 in left field, his first career outfield work. He’s not viewed as a great defender anywhere but could rotate between second base, left field and designated hitter. Meidroth hits right-handed, as do bench pieces Derek Hill and Tanner Murray.
