The White Sox went looking for a bargain at the deadline, but the Luis Castillo deal has only looked worse with each passing week.
Castillo arrived in Chicago with the kind of profile that can tempt a front office into believing it found a Guardians-style fix: a proven veteran, still under contract, available because this season had gone sideways. The White Sox paid for that gamble with prospect Boston Smith and former Guardians outfielder Nolan Jones, and at the time the move at least had the shape of a shrewd buy-low swing.
That version of the story hasn’t held up.
Castillo has been hammered for a 7.76 ERA across his first seven starts with the White Sox, and the organization finally pulled the plug on his rotation spot over the weekend. He has since made two appearances out of the bullpen, including a rough first outing in relief when he gave up three runs in 2 2/3 innings in a loss to the Cardinals. Yesterday, he tossed a scoreless inning in relief in Chicago’s big win over the White Sox.
That kind of deployment is more fitting for a Rule 5 pick than a deadline centerpiece, but that’s where Castillo is now after a season that has gone off the rails.
Last week, general manager Chris Getz said the quality of Castillo’s pitches had “ definitely gone in the wrong direction, ” and there’s not much reason to expect a dramatic turnaround in the final week of the season. Castillo is 33, and the price attached to him is not small. He is making $24.1 million this season and will make the same amount next year, which has turned what once looked like a manageable contract into a burden.
The White Sox’s rotation problems have only made the situation uglier. Since the start of August, Chicago starters have posted a 5.41 ERA, a stretch that has helped open the door for the Guardians to move ahead in the American League Central. Castillo’s turn was handed to David Sandlin, who had an okay first outing before getting shelled by the Tigers on Friday.
The Guardians have built a reputation for helping veteran pitchers rediscover themselves, but they usually do it with cheaper bets from the bargain bin. Chicago tried to copy the formula without the same safety net, and now the trade looks like a misfire that could carry real financial consequences next season.

Guardians Could Have A Few Surprise Arms Waiting For October
The Guardians have opened a stay hot camp at Triple-A Columbus for players on the 40-man roster who are not on the major league club, giving them a place to keep sharp as October approaches. The group also includes a few other minor leaguers, with the idea being straightforward enough: stay ready, stay available, and be prepared in case Cleveland needs to make a postseason move.
Several of the names in camp are pitchers, along with some hitters, and a few are still working back from injuries. With the postseason roster still a moving target, the biggest area of flexibility may end up coming on the mound, where the Guardians are weighing different ways to cover any late needs without disrupting what has already carried them this far.

Guardians Fans Now Know What This Clase Trial Really Hinges On
Federal prosecutors have now put a sharper frame on the case against Emmanuel Clase, identifying 18 specific pitches they say the Guardians closer allegedly threw intentionally to help bettors who had paid him bribes. The new court filing lands ahead of Clases November trial and gives Cleveland fans a clearer sense of how the government plans to present its case, with former teammate Luis Ortiz also charged in the same alleged scheme.
Both players have pleaded not guilty and remain suspended by Major League Baseball as the legal process moves forward. The case centers on accusations of wire fraud conspiracy and money laundering tied to a betting operation that reportedly netted more than $460,000, and the latest filing suggests the trial may turn on those pitch-by-pitch allegations rather than the broader outlines of the scheme alone.

Guardians May Be Sending Tanner Bibee A Tough October Message
Tanner Bibee looked like a foundational piece for Cleveland when he signed a five-year extension in March 2025, coming off two strong seasons that had established him as one of the organizations most important young arms. Since then, his year has been far more uneven, with his ERA climbing and an American League-leading loss total underscoring how difficult things have been at times.
Now the Guardians are reshuffling their postseason rotation, and Bibee may be staring at a very different October assignment than the one he expected when the year began. A move into the bullpen would not erase the promise that made Cleveland commit to him, but it would be a clear sign that the club is prioritizing roles and matchups over status as the games get bigger.
