The Chicago White Sox head into the 2026 season with cautious optimism and a roster that feels far more promising than it did a year ago.
After improving by 19 wins in 2025, the organization is beginning to see progress from its developing core. Young talent has started to take hold across the roster, giving the team hope that a more competitive era may not be far away.
But with that optimism comes pressure.
As Chicago continues to stockpile prospects and build toward future contention, several current players will need to prove they deserve to remain part of the long-term picture. With young talent approaching the majors, the margin for error is shrinking.
Three players in particular enter the 2026 season with their roles far from guaranteed.
Miguel Vargas — 3B
Miguel Vargas' turnaround last season became one of the more encouraging storylines for the White Sox.
Acquired from the Los Angeles Dodgers at the 2024 trade deadline, Vargas initially struggled badly after arriving in Chicago. His difficulties carried into the early part of the 2025 season before a midseason swing adjustment changed the trajectory of his year.
The results were solid but not spectacular. Vargas finished the season with a league-average OPS+ of 100 while hitting 16 home runs. It was a significant improvement from his early struggles, but it still left questions about his long-term role.
Defensively, Vargas has yet to settle into a clear position. He split time between third base and first base but didn't establish himself as a standout defender at either spot.
For now, he enters 2026 as the team's primary third baseman. However, the White Sox pipeline is loaded with infield talent, and more help could arrive sooner than expected. Highly regarded prospect Roch Cholowsky is widely projected to join the organization's major league picture around midseason.
If Vargas fails to take another step forward offensively, the competition behind him could quickly become a serious threat to his playing time.
Davis Martin — RHP
Davis Martin quietly delivered a respectable season in 2025 while returning from Tommy John surgery.
The right-hander provided stability at the back end of Chicago's rotation, relying heavily on strong command rather than overpowering velocity. While his results were solid overall, some of the underlying metrics suggested that a bit of luck may have played a role in his performance.
That doesn't necessarily diminish Martin's value. Reliable innings from the back of a rotation are always useful, especially for a developing team.
The challenge for Martin is timing.
Chicago's pitching pipeline is quickly becoming one of the organization's greatest strengths. Highly regarded arms such as Noah Schultz, Tanner McDougal, and Hagen Smith are progressing toward the major leagues and could begin pushing for roster spots in the near future.
If Martin remains steady — or improves — he could secure a longer-term place in the rotation. But if his results remain average, the White Sox could explore trade options for the 29-year-old as they make room for younger, higher-upside pitchers.
Luisangel Acuña — OF
Luisangel Acuña arrives in Chicago with plenty of intrigue but still something to prove.
The White Sox acquired the former top-100 prospect from the New York Mets in the trade that sent Luis Robert Jr. out of Chicago. Despite his prospect pedigree, Acuña has yet to receive consistent opportunities at the major league level.
Now 24 years old, he appears set to receive exactly that chance in 2026.
Acuña is expected to see significant playing time in center field, bringing elite speed and dependable defense. However, his offense remains the biggest question mark.
He struggled at the plate last season, finishing with a .567 OPS. Still, the White Sox believe there may be untapped offensive potential in his profile. A strong showing in the Venezuelan Winter League offered some encouraging signs heading into the new season.
Early results in spring training have also been positive, with Acuña consistently making hard contact.
Even so, the opportunity in Chicago likely won't last forever. If the offensive struggles continue, the White Sox could eventually look outside the organization for help as they try to accelerate their climb back toward contention.
For Vargas, Martin, and Acuña, the 2026 season represents more than just another year on the roster.
It could determine whether they remain part of the White Sox's future — or become casualties of the team's rapidly developing rebuild.
