The White Sox keep finding ways to push youth into the picture, and the next wave could be even more interesting. Chicago already leads the league with 15 MLB debuts this season, and that number could still climb if Tanner McDougal gets into a big league game before the year is over. Even with all that turnover, the Sox have stayed in the fight and are still chasing a playoff berth.
If the current 40-man roster is any indication, there may not be many more debuts left in 2026. But 2027 is shaping up as a year when several of the organization’s more notable prospects could start arriving.
Roch Cholowsky is the clearest name to circle first. The White Sox drafted him with the idea that he could move quickly, and their decision to send him to High-A backed that up.
In his first 22 professional at-bats, he’s already put together an .801 OPS with a home run and two doubles. If he keeps producing through the stretch, Chicago could have him open 2027 in Double-A and possibly push for a midseason debut.
His ceiling is considered as high as anyone in the system, and he’s likely to sit atop the updated midseason rankings. For White Sox fans, his path alone is worth watching.
Caleb Bonemer is another name with a fast track. He entered the year as the club’s top prospect, though Cholowsky may soon overtake him.
Bonemer won Carolina League MVP in his first season and then followed that with a 29-homer year in his second. The bat is the real selling point here: if he can keep blending the power and contact traits he’s flashed over the last two seasons, he has the tools to become one of the better hitters in the majors.
He’s expected to finish the season in Birmingham and could be just one stop away from Chicago in Charlotte when 2027 begins. The only real question is where he ends up defensively.
William Bergolla Jr. brings a very different profile. He’s one of the more unusual prospects in the system, with elite infield defense and top-tier bat-to-ball skills, but almost no power or impact contact.
Even so, those defensive chops and his ability to get on base should translate. He could end up as the kind of utility infielder the White Sox can actually trust.
Bergolla posted strong offensive numbers in 11 games in Charlotte before an injury knocked him out, and he likely won’t play again in 2026. The expectation is that he returns to Charlotte in 2027 and sits right on the edge of a major league call-up.
Pierce George is the arm in the group. Chicago took him in the 13th round in 2024 knowing full well they were getting a reliever with real stuff and real control problems.
The walks were an issue in 2025, when he put up a 6.42 ERA in 47.2 innings at Kannapolis, though he opened this season by dominating in 10 games at that same level. After 15 solid outings at High-A, the White Sox moved him aggressively to Double-A.
He’s had a rough time there, posting a 7.64 ERA in 15 games for Birmingham, but the fastball is touching triple digits and he’s throwing more strikes with his cutter and curveball. If he steadies himself, George could be in Triple-A early in 2027 and in the mix for the White Sox bullpen before that season ends.

White Sox Make Another Catching Move That Raises A Bigger Question
The White Sox made another quick-catching adjustment this week, releasing Eric Haase from his minor league contract just after bringing him in. Haase got into seven games with Triple-A Charlotte, but his time in the organization ended before he ever surfaced as a real option for the big league club.
The move comes with the catching picture already looking a little tighter than expected. Chicago has been leaning on Drew Romo and Edgar Quero behind the plate, with Korey Lee next in line for depth, and the handling of Haase only adds to the sense that the club is sorting through its catching mix one piece at a time.

Drew Thorpe Just Gave White Sox Fans A Reason To Watch Closely
Drew Thorpes first outing for Charlotte on Aug. 13 was the kind of return the White Sox had to be encouraged by after a long recovery from Tommy John surgery and earlier elbow trouble. The right-hander looked in control from the start, working through five innings with a pitch mix that showed the same kind of feel and consistency that made him such an intriguing arm in the first place.
The part that will matter most to Chicago is how sharp the changeup looked, because that pitch has always been central to Thorpes profile and it was getting real swing-and-miss in his debut. If he can keep pairing that weapon with steady fastball life and the kind of command he showed in Charlotte, the next question is less about whether hes healthy and more about how quickly he can force his way back onto the White Soxs radar.

Luis Castillo May Be Giving The White Sox Rotation What It Needed
Luis Castillo has started to look more like the pitcher the White Sox were hoping they were getting when they brought him over from Seattle in the trade that sent Seranthony Dominguez, Nolan Jones and Boston Smith the other way. After a shaky stretch earlier in the season, Castillo has put together a run of better outings, and his most recent start against Cincinnati stood out for the kind of length and swing-and-miss stuff Chicago has been missing in its rotation.
A closer look at the adjustment points to a pitch mix change that could matter going forward. Castillo has leaned more heavily on his changeup, especially against left-handed hitters, and thats given him another weapon to keep lineups from sitting on his fastball and breaking stuff. For a White Sox staff that has needed stability and more reliable innings, the encouraging part is not just that Castillo has been better lately, but that the reason behind it may be something the club can count on.
