White Sox Designate Urquidy and Send Prospects to Fall League
The Chicago White Sox designated José Urquidy for assignment, reshaping their roster management following recent acquisition struggles. General manager Chris Getz previously faced scrutiny regarding the financial investment required to trade for Luis Castillo from the Seattle Mariners. Meanwhile, the organization plans to send nine players to the Arizona Fall League, which includes five top 30 prospects, matching the Los Angeles Dodgers for the highest total among Major League Baseball franchises. These moves follow a 10-1 victory over the Minnesota Twins as the team stays near the American League Central title race.
Why it matters
The franchise continues to navigate fluctuating roster decisions while evaluating recent acquisitions and high-upside players. Castillo remains a focal point of scrutiny for the front office due to the cost of bringing him from Seattle and his ongoing performance issues.

The Chicago White Sox are altering their pitching rotation by pushing back Luis Castillo to focus on mechanical work, keeping their roster decisions in flux. While the team recently secured a series win against the Minnesota Twins with a 10-1 victory and remains close to the American League Central title, deadline acquisitions like Castillo continue to struggle. General manager Chris Getz has faced scrutiny over the financial investment required to acquire Castillo from the Seattle Mariners, as the front office targets players with untapped upside.
Why it matters
The White Sox are balancing a strong push for the AL Central crown against the underwhelming performance of key acquisitions. The ongoing rotation adjustments highlight the team's reliance on internal depth and development as the regular season reaches its final weeks.
What is confirmed

White Sox maintain AL Central lead despite Luis Castillo struggles
The Chicago White Sox remain close to winning the AL Central title while their deadline acquisitions struggle to provide immediate impact. A recent 10-1 victory over the Minnesota Twins secured a series win and bolstered the team's standing. Despite the success of the broader roster, pitcher Luis Castillo continues to underperform after joining the team from the Seattle Mariners. General manager Chris Getz has faced criticism for the financial cost of the Castillo deal, though the team's current strategy focuses on players with untapped upside.
Why it matters
Chicago is locked in a tight race with the Cleveland Guardians for the division lead with less than a month left in the season. The team assumed $30 million of Castillo's contract to bolster the rotation. The current playoff push relies on a remodeled player acquisition process.
What is confirmed
- The White Sox defeated the Minnesota Twins 10-1 to win the series.
- Luis Castillo has a 7.52 ERA after surrendering six runs over six starts since joining Chicago.
- Chicago paid $30 million for the remainder of Castillo's contract in a trade with the Seattle Mariners.

White Sox Face Scrutiny Over Luis Castillo Trade And $30 Million Deal
The Chicago White Sox are fighting off the Cleveland Guardians to hold the AL Central division lead with under one month remaining in the regular season. Recent performance struggles from trade deadline acquisition Luis Castillo have escalated scrutiny surrounding general manager Chris Getz's roster additions. Castillo surrendered six runs over six starts since joining the team, driving his ERA to 7.52 following a 6-2 defeat against the Houston Astros. USA Today reporter Bob Nightengale highlighted that Chicago assumed $30 million for the rest of Castillo's contract in a deal with the Seattle Mariners, drawing heavy criticism.
Why it matters
The White Sox previously led the AL Central at the trade deadline and acquired pitching help to secure their playoff positioning. However, the heavy financial commitment to Castillo now threatens to saddle the organization with a declining player under a burdensome contract. Meanwhile, off the field, Justin Ishbia's company Canal Edge announced plans for a potential stadium move to the South Loop called The Railyards.
What is confirmed
- The Chicago White Sox acquired pitcher Luis Castillo from the Seattle Mariners, absorbing $30 million remaining on his contract.
- Luis Castillo owns a 7.52 ERA over six starts with the White Sox.
- Justin Ishbia's company Canal Edge announced plans to potentially carve out space for a new stadium named The Railyards in the South Loop.

The Chicago White Sox face a pitching crisis as Luis Castillo fails to consistently provide length in his starts. While the team leads its division, late-season slumps and injuries among trade deadline acquisitions have created doubt about their ability to anchor a postseason run.

White Sox Roster Shifts Follow Luis Castillo Trade
The Chicago White Sox are adjusting their roster following the acquisition of pitcher Luis Castillo from the Seattle Mariners. To create a spot for Hagen Smith, the team designated pitching prospect Wikelman Gonzalez for assignment.

Meanwhile, the Mariners continue to struggle with offensive consistency as they enter the final 45 games of the season.
