The White Sox didn’t just shop at the trade deadline - they took three swings that now look a lot less convincing in hindsight.
That’s the trap with deadline deals. You’re buying future performance with incomplete information, and every move comes with risk.
Chicago was trying to patch holes without gutting its recently built-up depth and prospect stash, which is a tricky balancing act. Still, even with that context, the returns on their biggest additions have been rough enough to make the alternatives feel pretty obvious.
The Sox came away with four central pieces: catcher Joey Bart, right-hander Luis Castillo, reliever Huascar Brazoban, and outfielder Brenton Doyle as a bench addition. Of that group, Castillo, Brazoban, and Bart have all disappointed, and Brazoban and Bart are now on the injured list.
One obvious place to look back is the rotation. Instead of Castillo, the White Sox could have chased left-hander Robbie Ray.
Chicago sent Nolan Jones, Boston Smith, and Seranthony Dominguez to the Seattle Mariners for Castillo. Dominguez is still a usable veteran arm despite getting hit hard this year, Jones was mostly extra outfield depth, and Smith was the real headliner in the deal - a 40 FV catcher with some pop, and that power has shown up with the Mariners.
Ray’s market wasn’t wildly out of reach. The Padres landed him from the Giants for Miguel Mendez and Joniel Hernandez, with Hernandez carrying a 40+ FV grade and Mendez listed at 45.
Mendez also brings value as a pitcher with strong swing-and-miss numbers and a good 2025. Smith stacks up reasonably well against Hernandez, and if the Sox wanted Ray, they likely would have needed to include one more piece better than the Dominguez/Jones combination, though not by a huge margin.
Maybe a package built around Dominguez and someone like Mathias LaCombe, Chicago’s No. 18 prospect and a 40-grade right-hander on MLB.com, would have done it.
The performance gap matters too. Castillo was sitting on a 5.06 ERA in 99.2 innings when the White Sox got him, and he has followed that with a 5.89 ERA in four starts covering 18.1 innings.
Ray had a 3.08 ERA in 122.2 innings before the deal and has posted a 3.98 ERA over four starts and 20.1 innings since. In other words, neither pitcher has suddenly become a different guy, but Ray has been the better version of this same bet all season.
He also would have given Chicago another left-handed arm behind Anthony Kay.
Catcher is the other spot where the White Sox may have overpaid in opportunity cost. They sent Duncan Davitt, a right-handed pitcher parked in Triple-A, to get Joey Bart.
On paper, that wasn’t an ugly move. Davitt had a 6.22 ERA in Charlotte, Bart had been serviceable, and Chicago badly needed help behind the plate.
Then Bart went hitless in three games and landed on the injured list, which is about as bad as that trade could have gone.
A different route would have led to Hunter Feduccia. Before the trade, Feduccia had a .646 OPS and an 80 OPS+, almost matching Bart’s .680 OPS and 86 OPS+.
Since going to the Dodgers, Feduccia has hit .774 OPS. That may not hold, but he has already appeared in 18 games, which makes him more useful right now than Bart.
Los Angeles got Feduccia by parting with bonus pool money and depth outfielder Jack Suwinski. Suwinski hasn’t appeared in the majors this season and posted only a .534 OPS for the Pirates last year. The White Sox wouldn’t have been dealing bonus pool money, but they likely could have built a similar structure around one of their own depth outfielders and a mid-level prospect.
Then there’s the bullpen move. Chicago acquired Huascar Brazoban from the Mets for Gabe Davis and Zach Franklin.
Brazoban had been excellent for New York, with a 2.56 ERA in 52.2 innings, and Davis and Franklin were not Top 20 prospects. Davis projects as a potential starter with a 35+ FV, while Franklin is a major league-ready reliever.
But Kirby Yates was there too. Before the Pirates dealt for him, he had thrown 27.1 innings with a 3.95 ERA.
That’s not flashy, but it works. Since the trade, he has logged 11.1 innings with a 2.38 ERA.
Brazoban, meanwhile, has thrown 10 innings to a 6.30 ERA and is now on the 15-day injured list. The White Sox probably could have made a Yates deal with either Franklin or Davis instead of both.
Yates is 39, Brazoban 36, so age was a factor either way.
Not every White Sox deadline move was doomed from the start, and in some cases the players they acquired looked better on paper than the names above. And there’s still time for Castillo, Bart, and Brazoban to turn things around, especially once the last two return from the injured list. But right now, it’s tough to shake the feeling that Chicago had better options sitting there.

White Sox Rebuild Faces A Farm System Question Fans Cant Ignore
ESPNs Kiley McDaniel slotted the White Sox farm system 20th in his latest MLB rankings, a reminder that the organizations rebuild is still being judged not just by whats happening in Chicago, but by the talent pipeline behind it. The ranking, built from a Future Value-based system informed by FanGraphs evaluations, comes after a wave of player graduations and additions has kept the system in motion, with the club continuing to rely on young arms and position players to shape the next wave.
For a fan base watching every layer of the rebuild, the number is less a verdict than a snapshot. The White Sox still have prospects drawing attention for their performances and long-term upside, and their affiliates are supplying fresh game action that can alter the picture quickly. The challenge now is the same one it has been for a while: turning encouraging individual seasons into enough depth and impact to push that farm ranking higher before the standings in Chicago start to matter again.

Caleb Bonemer Is Giving The White Sox A New Reason For Hope
Caleb Bonemer keeps giving the White Sox another reason to think bigger about their next wave of talent. The top prospect has started taking reps in center field, a move designed to add versatility to his profile and potentially speed up his climb toward the majors. He even made his professional debut start there in a recent game, another sign the organization is willing to stretch his responsibilities while working him closely with coaches on the adjustment.
For the White Sox, the appeal is obvious. If Bonemer can handle a premium defensive spot, he becomes even more useful as a future option, much like Sam Antonacci earlier this season when added flexibility helped shape his path forward. The move does not guarantee anything on its own, but it does show the club is thinking about ways to make Bonemers rise smoother, faster and more valuable when the time comes. [Read more 🡒]
Davis Martins Return Could Answer A Big White Sox Rotation Need
Davis Martins first step back went about as well as the White Sox could have hoped. In his minor league rehab outing after landing on the injured list with a blister issue, he worked five scoreless innings, gave up one hit and struck out five, giving the club a useful reminder of what he can offer when hes on the mound and right.
For a rotation that has been looking for stability, Martins progress matters beyond one clean rehab start. The White Sox are hoping he can keep building without any more blister trouble, with an early-September return still the target if all goes smoothly. If he gets there, it would give the staff a much-needed arm back at a time when every healthy starter counts. [Read more 🡒]
