The Arizona Fall League is still giving White Sox prospects a chance to get work in before the calendar flips toward winter, and Chicago has five players in the mix with the Glendale Desert Dogs. But with the Desert Dogs sitting at 5-12 and effectively out of the playoff race, the bigger story is how each Sox arm and bat has handled the extra run of games.
Caleb Bonemer has been the clear standout. The White Sox’s No. 2 prospect and No. 27 overall will leave the Fall League early after 13 games, according to MLB.com’s Sam Dykstra, but he made the most of his time in Arizona.
Bonemer followed up a strong regular season in which he hit .251/.380/.550 with 37 home runs and 92 runs driven in across 132 games between High-A and Double-A by producing even more loud contact in the Fall League. In 13 games, he hit .286/.364/.633 with three home runs and nine total extra-base hits.
He also got a good dose of center field work, playing the outfield in 12 games. It wasn’t spotless, but the reps were part of the point, and he’s leaving with that box checked.
The early exit makes sense, too. Bonemer has played 145 total games this year, so even with the strong health update, the workload has clearly piled up.
After Bonemer, the production drops off quickly. Colby Shelton, the White Sox’s No. 23 prospect, has hit .206/.310/.294 with one home run in 12 Fall League games. That comes on the heels of a regular season where he slashed .244/.338/.488 with 24 home runs.
Anthony DePino, Chicago’s No. 21 prospect, has yet to take an at-bat in Arizona despite putting together a strong year in the system. He hit .262/.363/.481 with 25 home runs.
On the pitching side, Pierce George has barely been used. The White Sox’s No. 18 prospect has appeared in one game, allowing one run in 0.2 innings while issuing three walks and striking out one batter.
Mathias LaCombe, the top-ranked Sox prospect in this Fall League group behind Bonemer at No. 17, hasn’t matched the stretch he put together down the line in 2026. In five games and six innings, the French-born right-hander has allowed four runs on five hits and five walks. The expectation in Arizona was higher, but the results haven’t followed.
One unranked name has quietly put together a better showing than some of the more notable prospects. Nick Altermatt has allowed just one run on three hits and three walks while striking out seven in six Fall League appearances, covering 4.2 innings. If he keeps pitching like this into 2027, he could force his way onto the watch list.

Colson Montgomery Gave The White Sox Hope And One Huge Concern
Colson Montgomerys 2026 season gave the White Sox plenty to build on at shortstop. He played in 153 games, led American League shortstops with 31 home runs and 87 RBIs, and finished with a 2.8 WAR, the kind of everyday production Chicago has been waiting for from the position. Even with the offensive value, his defensive metrics stayed strong enough to suggest theres a real long-term piece here, not just a power surge.
The concern, though, is how narrow the path to that production appears to be. Montgomerys contact quality dipped from his 2025 debut, his chase rate climbed, and the swing-and-miss issues were impossible to ignore over the course of the year. The White Sox can live with some strikeouts from a power-hitting shortstop, but if the swing decisions and fastball handling do not improve, the ceiling comes with a fairly obvious catch.

Caleb Bonemer Is Giving White Sox Fans A Prospect To Watch
Caleb Bonemer has been one of the more eye-catching White Sox prospects in the Arizona Fall League, where his tools have shown up in a way that gives the organization something tangible to point to this fall. He has been standing out with his blend of raw power and speed, the sort of athletic package that tends to get noticed quickly when prospects are trying to make their case in a showcase setting.
Bonemer also turned in a big game for Glendale, adding extra-base hits in a convincing win over Mesa and reinforcing why he has become a name to keep circling on the White Sox prospect map. Within the organization, some in player development are even looking at his frame and athleticism and seeing a familiar kind of upside, which only adds to the intrigue as he continues to build momentum in front of evaluators.

White Sox Still Have Two Costly Obstacles This Offseason
After a 2026 season that pushed the White Sox into the ALDS and finally got them back into the win column in October, the front office now has a different kind of offseason problem to solve. Chicago has momentum to build on, but it also has to decide how to handle a pair of pricey veterans who no longer fit neatly into a long-term plan.
Andrew Benintendi and Luis Castillo sit near the center of that discussion because both carry meaningful money and limited margin for error. Benintendi is down to one year on his deal, while Castillos contract stretches into the next couple of seasons and has been complicated by his performance and injury history, leaving the White Sox to weigh whether there is any real market for either player or whether they are better off holding on and hoping for a bounce-back.
