White Sox Begin Next Phase with Noah Schultz Debut as Sosa Trade Opens Door for More
The next phase of the White Sox rebuild arrives Tuesday night. Top pitching prospect Noah Schultz is set to make his Major League debut against the Tampa Bay Rays, giving Chicago its first look at the highest-upside arms in the organization.
The 22-year-old left-hander has overmatched Triple-A hitters to open the season and now gets his first shot at the highest level as the White Sox begin to lean more heavily on their upper-level talent.
Schultz is the headliner, but he may not be the only Charlotte name worth watching.
The White Sox have discussed the possibility of promoting infielder/outfielder Sam Antonacci this week, though nothing has been finalized.
The versatile left-handed hitter has continued to build momentum with his early production in Triple-A (154 wRC+), and Monday’s trade that sent Lenyn Sosa to Toronto created another opening on the roster as Chicago continues to shuffle pieces at the major league level.
For now, Tuesday belongs to Schultz. But with Antonacci in the conversation and more roster movement already underway, the White Sox appear to be moving into the next stage of evaluating what their next core could look like.
Noah Schultz Earns His Call to White Sox
Noah Schultz’s promotion comes with little left to prove at the Triple-A level.
Across three appearances with Charlotte, the 22-year-old left-hander overwhelmed hitters to the tune of a 1.29 ERA with 19 strikeouts over 14 innings, allowing just four hits and two walks.
Schultz has struck out over 40% of opposing hitters while holding them to a sub-.100 batting average, consistently working in the zone and avoiding the command issues that surfaced at times in 2025.
That version of Schultz looks much closer to the one the organization envisioned.
After battling patellar tendinitis last season, his delivery and stuff have both taken a step forward early in 2026. His fastball has ticked back up into the mid-to-upper 90s, touching 99 mph, while his trademark slider has regained its sharp, sweeping action.
The pitch remains one of the most effective swing-and-miss offerings in the minors, generating chase both in and out of the zone.
Just as important has been the overall development of his arsenal. The No.1 prospect on the FutureSox Preseason List is no longer relying on a two-pitch mix. He has incorporated a cutter more consistently, regained feel for his curveball, and shown increased confidence in his changeup, giving him a true five-pitch mix.
His velocity and pitch separation has made him especially difficult to pick up, with hitters often forced to commit early against a release point that creates deception from his 6-foot-10 frame.
Opponents have struggled to generate quality contact, with low expected damage across his pitch mix and limited hard-hit outcomes. Even when hitters do make contact, it has rarely been impactful.
Schultz’s promotion comes amid a stretch of heavy pitching staff churn. With Shane Smith optioned and both Duncan Davitt and Jonathan Cannon moving between Charlotte and Chicago, the White Sox have cycled through arms while searching for stability.
Unlike those recent depth moves, Schultz arrives as the highest-upside addition and a pitcher the organization believes can hold a meaningful role moving forward.
With a rotation spot now open and a growing emphasis on evaluating long-term pieces at the major league level, Schultz becomes the first significant pitching addition from the next wave. His early strike-throwing efficiency and improved pitch mix point to a pitcher prepared for the opportunity.
There will still be an adjustment period, and workload will remain a factor after a shortened 2025 season. But based on his early returns, Schultz has positioned himself to handle a meaningful role rather than a short-term appearance.
Tuesday marks his debut.
It may also mark the beginning of a longer stay in Chicago.
Sam Antonacci Emerging as Next in Line for White Sox
While Schultz’s promotion is set, Sam Antonacci remains a name firmly in the conversation.
The White Sox have discussed the possibility of bringing the 23-year-old up this week, though no move has been finalized. Multiple reports indicate the decision is still being weighed internally, making his timeline less certain even as momentum builds around his early-season performance.
Antonacci had eyes on him early in the year after his WBC performance with Team Italy and has done everything he can to force the issue.
Through his first stretch in Triple-A, the left-handed hitter has reached base at a high clip, continuing a trend that has defined his rise through the system.
That production is backed by strong underlying contact metrics, including over 85% overall contact and above-average zone contact rates, while maintaining a disciplined approach with a chase rate well below league average.
That approach is what separates him. The ninth-ranked player on the FutureSox Preseason Top 30 list doesn’t rely on power to impact the game.
Instead, he puts pressure on pitchers with consistent contact and an ability to get on base in multiple ways. His profile is built around controlling the strike zone and limiting swing-and-miss, and early data suggests that skill set has translated cleanly to Triple-A pitching.
There are also signs of growth within that profile. While not known for power, Antonacci has shown vast improvements in batted ball quality, particularly on balls in the air and against certain pitch types. His 90th-percentile EV is above 103 mph, and what was once a concern now seems like an area where he could surprise.
His ability to handle velocity and make consistent contact across the zone has allowed him to remain productive without needing to sell out for power.
The White Sox have also expanded his defensive role. Primarily an infielder throughout his career, Antonacci has seen increased time in left field this season. The added versatility gives the organization more flexibility if and when he is promoted, especially on a roster that has been searching for consistent production from multiple spots.
For now, his status remains unresolved.
But with his performance in Charlotte, the organization continues to evaluate its options. Antonacci has positioned himself as one of the next potential pieces to arrive.
Sosa Trade Opens the Door for White Sox
Monday’s trade involving Lenyn Sosa added another layer to the White Sox early-season roster reshuffling.
Chicago sent Sosa to Toronto in exchange for 2025 17th-round pick outfield prospect Jordan Rich and future considerations, moving on from one of the team’s more productive bats from a year ago.
Sosa led the club with 22 home runs in 2025, but his role had already started to shrink early this season. Defensive limitations and a lack of positional flexibility made it increasingly difficult to keep his bat in the lineup consistently, particularly as the White Sox have emphasized run prevention and versatility under Will Venable.
With Sosa out of options and limited to a reduced role, the White Sox chose to reallocate that roster spot rather than continue forcing an imperfect fit. In return, they add Rich, an 18-year-old Florida native with athletic upside, viewed more as a long-term developmental piece, and he’ll likely start in Arizona with the Complex Team.
With Noah Schultz set to be added ahead of his debut, Chicago needed space on both the active roster and the 40-man. Sosa’s departure helps facilitate that move while also opening a path for an additional position player if the organization decides to act.
While no decision has been finalized, the opening created by the trade gives the White Sox a clearer avenue to bring up a versatile bat if they determine the timing is right.
Antonacci fits that spot, offering on-base ability and defensive flexibility across multiple spots, traits the current roster has lacked at times early in the season. The structure is now in place for Antonacci, or another position player, to step into a role if the club chooses to make another move.
Everson Pereira has been reinstated from his rehab assignment, and a move such as optioning Tristan Peters could help balance the position player group.
On the pitching side, the situation remains fluid. The White Sox have already cycled through multiple arms in recent days, and that may continue, especially with Jonathan Cannon leaving his most recent outing with right hip irritation.
A potential injured list stint would create another avenue for roster flexibility, while bullpen arms like Bryan Hudson or Brandon Eisert could also be optioned depending on how the staff is aligned.
Stepping back, the deal also reflects the broader direction of the organization.
Rather than holding onto established roles from last season, the White Sox are actively turning over the roster in favor of younger, more adaptable pieces. Recent transactions across the pitching staff and bench have reflected short-term maneuvering, but this move carries more long-term implications.
It’s not just the talent being evaluated, but the semantics of how this roster is being built and reshaped in real time.
Schultz’s promotion represents a potential cornerstone on the pitching side, while the Sosa trade and the possibility of Sam Antonacci’s call-up behind it signals the same approach taking shape on the position player side as well.
