Chris Clegg breaking down a few players on Glendale’s Arizona Fall League team. Featured two Sox players.
Best Arm
Hagen Smith had a rough year on paper, especially in the walk column, putting 17.6 percent of batters he faced on base via walk. In his final regular-season start, we saw the epitome of what Smith looked like this season. He pitched four innings and allowed just one hit, while striking out six. But he walked six batters, which was the consistent issue all season.
Smith’s fastball lives in the 94-96 range, generating 14-15 inches of IVB from a 5’7” release height, getting 13 inches of horizontal movement. The pitch is highly effective, even when he does not hit his spots consistently.
Smith’s slider morphs into a cutter at times, with some having -5 inches of IVB, while others have shorter horizontal and 4 inches of IVB. You can see in the video below that some had longer sweeping action, and he used the pitch efficiently against lefties and righties. The slider sits in the lower 80s while the cutter was in the 85-87 mph range.
Smith will throw changeups on occasion, sitting around 90 mph. The pitch shows good carry, having 11 inches of IVB and playing pretty well off the fastball before diving off with 15 inches of fading action.
Reminder, being at Camelback Ranch in Glendale is the White Sox complex. He is sure to already be working on things, so his command and control will be something to watch closely in the Arizona Fall League.
Bat Who Could Increase Stock
Sam Antonnaci put together a highly impressive 2025 campaign after the White Sox selected him in the fifth round of the 2024 MLB Draft out of Coastal Carolina. Splitting the season between High-A and Double-A, Antonnaci slashed .291/.433/.409 with five home runs and 48 stolen bases. Sure, you want to see a little more home run power, but Antonnaci did add 32 extra-base hits to his ledger.
While the profile is built on contact, the exit velocity data is better than you might expect. Given the high OBP, it should not be surprising that Antonnaci has a strong approach. His chase rate around 16 percent is highly impressive, and Antonnaci shows respectable swing rates on pitches in the zone.
Antonnaci ended the year with an overall contact rate of around 87 percent, and the in-zone number was just shy of 90 percent. Ground balls limited Antonnaci in High-A as he posted a 48 percent ground ball rate, which dropped by five percentage points in Double-A. The exit velocities were respectable, as his 90th percentile exit velocity of 102 mph will play for someone with his contact and speed.
If Antonnaci can pop a few home runs in Arizona and run wild, he could have a Caleb Durbin-type buzz
