Two White Sox Prospects Named Arizona Fall League All-Stars

This time last year, it was Sam Antonacci, Braden Montgomery, and Hagen Smith representing the Chicago White Sox in the 19th annual Fall Stars Game, which showcases the top performers from the Arizona Fall League.

All three prospects had yet to make their Major League debuts, but each showed signs of becoming a future star during their time in the AFL. Now, here we are in 2026, with Antonacci, Montgomery, and Smith all contributing to a White Sox team that reached the postseason. Antonacci is even a finalist for an American League Silver Slugger Award.

And now, we have a new group of White Sox prospects being named Fall Stars.

After shining for the Glendale Desert Dogs this year, Caleb Bonemer and right-handed pitcher Jonathan Clark have both earned the honor.

What more can be said about Bonemer at this point? He's the No. 2-ranked prospect in the White Sox organization and the No. 27 prospect in all of baseball.

During his age 20 season, he hit 37 home runs, 29 doubles, and recorded 16 stolen bases while splitting time between High-A Winston-Salem and Double-A Birmingham.

Bonemer can drive the ball with authority to all fields, and he's an underrated athlete who has been using that athleticism to transition to the outfield over the final few weeks of the regular season and during Arizona Fall League games. Moving to the outfield should expedite Bonemer's path to playing time in Chicago.

There were plenty of positive reviews about how he looked defensively in the Arizona Fall League, and he never stopped hitting. In 13 games for the Desert Dogs, Bonemer hit four doubles, two triples, and three home runs while recording 12 RBIs and posting a .996 OPS.

That performance earned him a selection to the Fall Stars Game, but his time in the AFL has already come to an end, and he won't be participating in the game.

The White Sox will still be represented, though, by 26-year-old right-handed pitcher Jonathan Clark, a reliever who joined the organization in 2025 as an undrafted free agent.

Clark has productively worked his way through the minor leagues and made 50 total appearances between High-A Winston-Salem and Double-A Birmingham in 2026. He finished 9-3 with a 4.10 ERA and 70 strikeouts in 59.1 innings pitched.

He's 26 years old, and he's exclusively a relief pitcher, so you won't find Clark on any top prospect lists. The White Sox may have found a future bullpen contributor in Chicago, though, and with his production in the AFL, I expect Clark to start the 2027 season in Triple-A Charlotte knocking on the door of a big league debut.

He's pitched in seven games for the Desert Dogs, posting a 3.24 ERA with 13 strikeouts in 8.1 innings pitched. That's a K/9 of 14.0, the highest Clark has recorded since he played in the California Collegiate League back in 2023.

The last three White Sox prospects to be named Fall Stars came up and contributed to the big league team the following year. That's already somewhat of a given for Bonemer, but don't be surprised if we see Clark in Chicago next year, too.

His success is a testament to the organization's ability to find and develop talent, even when it comes in the form of an undrafted free agent playing in the Pioneer League.
