The Arizona Fall League is underway, and Chicago has seven prospects in the Grand Canyon State. The crew includes Mathias LaCombe, RHP (No. 17); Colby Shelton, INF (No. 23); Nick Altermatt, RHP; Jonathan Clark, RHP; Grant Magill, C; Tommy Vail, LHP and Garrett Wright, RHP.
The team added Vail after Pierce George, RHP (No. 18), suffered an olecranon fracture in his pitching elbow. While it sounds like an awful injury, he is expected to participate in 2027 Spring Training. Anthony DePino, INF (No. 21),
was also originally on the Dogs roster, but instead underwent shoulder surgery. He should also be ready for spring.
Caleb Bonemer, 3B/SS/OF (No. 2/MLB No. 27), concluded his fall stint on Oct. 24 after slashing .286/.364/.633 with a .996 OPS in 13 games. Over his 49 at-bats, he hit four doubles, two triples and three homers, with six walks, 12 RBIs and an equal number of Ks. Shelton also appears done for the season, as he’s no longer listed on the Dogs’ roster. He finished hitting .277/.379/.511, with an .890 OPS in 15 games.
The White Sox prospects are suiting up for the Glendale Desert Dogs (9-17), sharing the dugout with hopefuls from the Atlanta Braves, Los Angeles Dodgers, Miami Marlins, and Pittsburgh Pirates.
Glendale Desert Dogs 10, Mesa Solar Sox 5 (11/3/26)
Vail was the only Chicago prospect to participate in the win. He tossed a hitless, scoreless seventh, retiring the side in order.
Glendale Desert Dogs 2, Surprise Saguaros 0 (11/4/26)
Magill’s struggles at the plate continue, as he went 0-for-3 with two Ks. Clark earned his first save despite loading the bases in the top of the ninth. Fortunately, he pitched around the traffic and secured the final out.
Mesa Solar Sox 6, Glendale Desert Dogs 3 (11/5/26)
It’s been a messy fall for LaCombe, and this outing didn’t help. He entered in the top of the seventh and got a ground out before loading the bases on a single and back-to-back walks. A strikeout put him one out from escaping the jam, but a two-run single ended his afternoon. Altermatt took over and got the final out, then returned for the eighth. After retiring the leadoff hitter, he had to work around an error by the second baseman. A single, ground out and double brought home two unearned runs, and a free pass put runners on first and second with two gone. Altermatt finally shut the door on the inning with a grounder.
Scottsdale Scorpions 1, Glendale Desert Dogs 0 (11/6/26)
Wright did his part to keep this one close, tossing a scoreless frame in the third and surrendering just a hit.
NL Fall Stars 7, AL Fall Stars 4 (11/8/26)
Both Bonemer and Clark earned spots on the AL Fall Stars squad, but only Clark saw action in the NL’s win. Bonemer wrapped up his fall stint on Oct. 24, while Clark faced three batters in relief. The righthander stopped the bleeding in the bottom of the eighth, entering with two outs, a runner on second and three runs already across. He struck out Wyatt Sanford to end the inning, then returned for the ninth and needed just one pitch to get a fly out before surrendering a single and getting the hook. His runner eventually scored after a walk, single and throwing error, leaving Clark with an unearned run on one hit over two-thirds of an inning, with no walks and one K.
