White Sox prospects highlight Chicago’s Arizona Fall League roster for Oct. 3-12 stretch

The Arizona Fall League has reached its Oct. 3 to 12 window, and the Chicago White Sox prospect pipeline is well represented in the desert. The Desert Dogs, Arizona Fall League’s offseason showcase team, are carrying a full group of nine Chicago prospects, a concentration that indicates the organization’s emphasis on development during the fall evaluation period.

At the center of the group is Caleb Bonemer, listed as a 3B/SS/OF profile and identified as the No. 2 prospect in Chicago’s system and the No. 27 prospect in MLB’s overall rankings by the report. His multi-position track record is part of what makes the Arizona Fall League especially relevant for teams like the White Sox, where organizational value often depends on both performance and athletic flexibility across roles.

Chicago’s infield presence goes beyond Bonemer with Anthony DePino, a 1B prospect, and Colby Shelton, an INF prospect. In the Arizona Fall League environment, that matters because the competition tends to be dense, with multiple clubs aligned on accelerated reps for players who need to refine swing decisions, defensive footwork, and game rhythm against advanced pitching and aggressive baserunning.

Pitching is another obvious emphasis in Chicago’s group. The reported roster includes Mathias LaCombe and Pierce George, both right-handers, along with Nick Altermatt, Jonathan Clark, and Garrett Wright. For prospects, having several arms in one organization’s contingent can also be a way to compare methods and adjustments in a common setting, even if each player’s role and development plan differ.

Rounding out the position group is Grant Magill, listed as the catcher on the Desert Dogs’ October 3-12 roster. In fall ball, catchers face a high workload of varied pitching profiles, and that workload can translate into an accelerated understanding of pitch tunneling, sequencing, and how to manage at-bats when hitters are trying to put extra emphasis on making contact and squaring up for higher-level reads.

The broader Arizona Fall League context is that the league runs as a concentrated proving ground in the offseason, blending prospects from multiple MLB organizations. Chicago’s decision to send nine players, including a top-tier infield talent and multiple pitching prospects, fits that model. It gives the White Sox a clearer view of which skills translate when the overall level of athleticism and pitching command rises quickly.

What to watch next in the Oct. 3 to 12 window is not just which individual names stand out, but how the group’s mix of positions and roles plays out. With multiple right-handers and a full infield-to-catcher set, Chicago will get reps that help separate players who can handle advanced hitters and pitch movement from those still working on consistency in the details.
