Hagen Smith Dazzles with 97 MPH Heat, Five Strikeouts in Three Innings

The No. 68 overall prospect Hagen Smith made the most compelling case yet for a White Sox promotion, striking out five over three innings without issuing a walk and touching 97.4 mph with seven swing-and-misses against Nashville on Friday night. Unfortunately, Charlotte still fell 4-0 to the Sounds, but the box score attached to Smith's line was almost beside the point.

The velocity number alone warrants attention. By the end of 2025, Smith's four-seam fastball velocity was back to the 95 mph average he displayed in his draft year after a rocky stretch that included elbow soreness and a mechanics overhaul. His four-seamer has dropped 2 mph at points, sitting at 92-95 mph and topping out at 97 in 2025, making Friday's 97.4 mph peak a meaningful signal: the stuff isn't just back, it may be trending past its previous ceiling. For context, Smith was averaging 96 mph every single outing at Arkansas before the pro ball grind trimmed those numbers. He appears to be reclaiming that version of himself.

Smith features a funky delivery off a four-seam fastball that sits around 94-97 mph, but his best pitch is a devastating 83-87 mph slider that paralyzes lefties with its horizontal and vertical action. Those two pitches, both graded as 65-grade offerings by evaluators, did the damage Friday. Seven swing-and-misses in three innings against Triple-A hitters is not accidental; it's what happens when a deceptive crossfire arm adds velocity to a slider that already plays as the best secondary pitch in the Charlotte rotation.

The walk-free performance deserves equal billing. Smith walked 56 batters in 75.2 innings at Double-A Birmingham in 2025, posting a 17.6 percent walk rate that represented the clearest obstacle between him and an MLB rotation. His short, quick, and forceful arm action drove a 40 percent miss rate at Double-A last season despite sitting 94 mph, meaning the strikeout ability was never in doubt. The command was. Zero walks in each of his first two Triple-A starts is a small sample, but it is exactly the pattern the White Sox need to see.

Charlotte manager Janish confirmed Smith would be limited to three innings for his first few outings, so the innings cap itself is not yet informative. What happens when that cap lifts is. Smith, Noah Schultz, and Tanner McDougal could all make their big league debuts in 2026, with their development starting at Truist Field.

The next genuine checkpoint on Smith's promotion clock is not his velocity or his slider. It is his changeup strike rate. He's still working on a split-grip changeup that averages 86 mph and reaches the low 90s with some sink, a pitch that played as below-average in 2025 but would enhance his repertoire if he improves it to fringe-average. Right now, Triple-A lineups can sit dead-red or hunt the slider with minimal threat from a third offering. The moment Smith starts throwing that changeup for strikes at a consistent rate, the calculus for Chicago changes entirely. That is the pitch that converts a two-weapon arm into a frontline starter, and it is the one development signal that will determine whether Smith's next big milepost is a June debut in Chicago or another month refining his third pitch in Charlotte.
